Game Maker Studio: Inventory Tutorial Video Lecture | Game Maker Tutorial: Build Games from Scratch - Game Development

alright guys welcome back so today we're
gonna be taking a look at how to build
an inventory system in game maker now I
fought about this topic for a long time
and I thought about how I might do it
from various different genre contexts
like how you might do an inventory for
an RPG or platformer or for a
point-and-click adventure game and
various different things but what I've
decided to do for this video is try and
do a Natori system with essentially no
context to show you the bare basics of
just setting up a system and setting up
an object that will track your inventory
and the objects in your inventory as
well as how to use code to add items to
your inventory and remove items from
your inventory and to check if an item
is in your inventory and then hopefully
with those tools at your disposal you'll
be able to kind of adjust this very
simple but pretty versatile system to
fit into pretty much whatever type of
game you're working on now because I'm
doing this tutorial independently of any
specific game context I'm not going to
be showing the absolute specifics of how
like you would start on the inventory to
be displayed and interacted with and how
you could click on a sword on the ground
and pick that up and put it in your
inventory because all that stuff is
gonna be specific to the game you're
making like all the stuff like how how
you click on one item in your inventory
and like move it to another place and
stuff or all that kind of stuff it
really depends on what it is you're
making but what I will show you is the
basics of how to interact with this
inventory in general so that you'll be
able to hopefully adjust and expand the
system to fit into whatever specific
type of game you're making should be
very clear how this works lay it wrong
so let's quickly walk through all the
resources that we've added to the
project so far there isn't really very
much I've got two sprites up here one
called SPR in-school border it's just a
little
little white box with transparency in it
I'm just using as a very simple thing
it's going to show we're just going to
draw to represent the slots of our
inventory on the screen I'm just doing
that really really at a basic level just
so that you can see the inventory
working more than anything we're not
really gonna be covering too much of how
to present the inventory level be more
up to you guys but uh that's there for
that and SPRs got items now this sprite
is important and it contains the
contains essentially the icons that
every item we want to have in the game
now I've stored essentially every item
in the game in one sprite called SP
underscore items as individual frames of
that sprite now normally you would use
frames of a sprite to store like an
animation right but here we're using
that same system differently and we're
just going to use every single frame of
this one sprite to store a different
item icon and the only other thing we
need in here is um RM underscore one or
just have a room nothing in it yet
so that's all I have right now and the
very first thing I'm going to do is
create our inventory object the object
that we're going to use to track our
inventory and to essentially manage
everything to do with our inventory so I
had an object on a create object call
this obj underscore inventory doesn't
need a sprite so it doesn't be visible
either but I am going to mark it as
persistent so that uh it carries over
between rooms so if we change runes
change levels like this object is going
to stick around and I'm just going to
reduce the depth to a generic - value
it's not going to max we're not going to
have any other objects in the game but
um the reason I'm doing that would be so
that if in theory we had a player object
or something like that or wow it's in
theory when we have the rest of the game
in the game we would want the
inventories probably draw over the top
of everything else because it's like a
an element of the UI so by sending it or
really really load that to that ensures
that it's drawing when it draws the
inventory on the screen it's going to
draw in front of everything else so the
first thing we want to do in here it's
what we're probably all used to by now
is going to advance add event and add
the create event our favorite then go to
control and drag in our favorite action
execute code and here we are back at our
lovely code editor the first thing I'm
going to do is just make a comment block
to remind myself um which item is which
number as you remember we have our
sprite each different frame represents a
different item so we need to know which
one of those images represents wine I'm
just going to create a comment block by
doing slash and then asterisk and then
down here asterisk slash and then you'll
notice anything I type in the middle of
here turns green and I've just created a
block comment sewing everything outside
of this is regular code and everything
in here is just a comment on one get
interpret by the game's code so here I'm
just going to type in the query items
you don't need to do this by the way
this is just as a thing to help out 0
was our sword 1 was our red potion 2 is
a blue potion and 3 was the yellow key
so those are our items now the next
thing I'm going to do is just establish
a couple of global variables for
inventory object and now you may have
seen the established global variables
before by typing in global and then
whatever the name of that variable is um
which works what I'm going to do this
time for these specific global variables
is actually going to use global var
instead now this does essentially
exactly the same thing only um I don't
have to specify a value to initialize it
to right away um
my create a global variable called show
in which is going to be a variable we
just used to control whether or not
we're currently showing the inventory on
the screen I can even call them at night
so we know what that does and I'm just
going to set it to true now the reason
I've used that this time mostly was just
to demonstrate the difference in this
tutorial is that now as you'll see when
I signed it underneath this is a global
variable and works just like previous
global variables and the it's very easy
for objects that other objects and other
code to interact with this variable um
as opposed to local variables where only
the specific object knows that that
variable exists but usually when I do
something like if I did global show an
equals sin church whenever I wanted to
refer to that variable again I would
have to type global dot Rho and every
time whereas having established this as
a global values ingush all I have to do
is write show and and it knows and it
will work in any object or in any script
after this has been initialized the game
knows that this is a global variable at
that point and will be able to reach and
access it from anywhere which really the
other day just saves you right in global
dot over and over anyway all that
variable is there for us to just track
whether or not we're showing the
inventory at the screen at any point in
time the next one global var max items
is just going to control the number of
slots the total is ones that we have for
our inventory um depending how your game
works I guess I figured my change over
time but it's just important for us to
track though the maximum number of items
that we want to store and I'm just going
to keep it really low just to be simple
I'm just going to set it to on Eve now
that we know how many items we want to
store we're going to do is create a
essentially a number of variables to
store which item is in which
not any one point in time now we're not
going to do what you might imagine and
say like item slop one equals two I mean
slop 2 equals item slot 3 equals
whatever and so on so forth that would
be like really unmanageable like it's
really hard to then know to refer to
specific items laws you've got to recall
the specific name of I am slot and so on
what we're going to do is use an array
to store what item is in which slot of
our inventory an array you can think of
it as multiple variables inside one
variable or a sequence of variables
stored inside essentially one word and
how that works is we write the name of
our variable and then put a number in
square brackets after that variable so I
could write inventory square brackets 0
to represent the very first entry of the
array equals 1 and then I could also
write inventory 1 equals 1 and so on so
forth inventory 2 equals 1 and so on
deport and now these are all essentially
variables in their own right like the
like 3 3 different variables the only
one because it I can change that or
whatever but the main difference here
between doing this and as I said doing
say item slot 1 equals 2 I'm still on
what 2 equals 4 etc the main difference
between doing this and doing this what
I've got set up here is that when I'm
referring through this array later I can
control much easily much more easily
control which slot I'm referring to so
if I have a variable is that slot equals
4 for example I could do an if statement
after that I said if inventory and then
in square brackets wrote slot equals
equals of
ten or whatever and then then write some
code after that and that would it would
take slot which equals four and it would
find the fourth entry in array which we
we did instead to say that one was for
for example I'm check to see if it
equals ten which is much much easier
like if we're choosing a specific slot
than having to say oh if slot equals
four and our and the name for our fourth
inventory slot was item swap for it
wouldn't help us because like we can say
it'd be much much harder to find
which variable we want to check so this
is why we're using an array to store our
items in specific slots now in order to
set up that array what I could do is I
could just say inventory as I did um
inventory zero the minus one we're going
to use minus one to store the idea of
having no item in a specific slot so
when there's no want and then a slot the
variable is going to be minus one
because otherwise we want it to be
either zero one two or three one of this
it's going to be either sword
red Persian blue potion or yellow key if
there is an item if there's no I am
minus one will be a figure now we could
establish our inventory of five items
like this one two three four so the
length is from zero to force those five
items there and we set them all to be
blank that would work but that's kind of
again makes things much harder to manage
burr is like what if we want to change
this later to fifty say they're not
awesomely then we've got to add like
fifty more of this line saying needs to
be all minus one that's a lot of hard
work so what we're going to do is I'm
going to use a for loop to set up our
inventory for us and so I'm going to
write for I equals zero let me go along
I less than manse items semi go on I
plus equal one close bracket open a
curly brace and close the curly
raise now what for loop does is it's
going to loop any code that's in here
a certain number of times now given that
it's setting a arbitrary variable here I
to be zero it's going to continue based
on I being zero to loop any code inside
these square brackets until this
condition is no longer true so at the
moment the condition is I this arbitrary
variable that we set to 0 is less than
max items max items being funny right
now
um so while I is less than 5 which it is
it's zero
so while I is less than 5 loop this code
but every single time it loops this code
is going to perform this thing on the
end here which is I plus equals 1 so
it's going to add 1 to I every single
time it loops this code until I is
bigger than max items at which point the
loop will stop so if you followed all
that you should understand that this for
loop is going to loop exactly 5 times
it's going to loop once with I equals 0
then with I equals 1 then with I equals
2 then with I equals 3 then with I
equals 4 and then after it's finished
with I equals 4 it'll do I plus I plus
equals 1 I will become 5 and I will now
be equal to max items therefore I less
than max items will no longer be true
and the for loop will stop if you want
to learn more about for loops like want
a more detailed explanation just middle
click on 4 or just go to for the full
statement and the the index and there's
a good explanation of it there so the
next piece of code I'm going to put in
here is I'm just going to say as we're
doing before our inventory open square
bracket I equals minus 1 so now instead
of having to write inventory 0 equals
minus 1 inventory 1 equals 9 1 and so on
so forth and just write inventory I
inside of this for loop
and because we know I is going to
increment all the way from zero to four
it's going to do inventory zero equals
minus one that's going to do inventory
one equals minus one inventory two
because minus one and so on so forth
the only other change I'm going to make
to this is I'm going to put global dot
in front of this so that we establishes
is a global global array therefore it
makes it easier for us because we can
access it from anywhere in the game and
that's it so we've essentially with this
code here like really really short
amount of code it's like eight lines um
we've set up our object and we've got
created five blank item slots and we can
usually change like if I just set that
eight or whatever we would have eight
blank line slots but we're just going to
stick with fine for now um now that we
have those iton slots available uh the
next thing I'm going to do is just set
it up so our inventory can draw the
contents of our inventory to the screen
even though we haven't actually added
anything to the inventory yet so I'm
going to add the drawer event dragon
code and first of all and here I'm just
going to say if show um this is what
allows that variable to work you
remember the global variable show in
that we set up in the create event
that's set to true um it means we can
set that to false any time and the game
will skip over our draw even entirely
and not rendering it at the screen and
then we get to turn it back on when we
do want to draw the inventory and so on
really simple now in here I'm going to
do I'm just going to do some very simple
kind of drawing stuff to just draw a
black rectangle at the top of the screen
which is where we're going to draw all
are in the Dorian stuff so the first
thing I'm going to do is I'm going to
type in VAR x1 x2 y1 and y2 now what I'm
doing here is I'm going to set up for a
coordinates that will eventually combine
to give us a rectangle of space so we
want
the left-hand side of that rectangle on
the right-hand side of that rectangle
the top and the bottom and we're just
going to store them in local variables
just to make things easy X 1 to the left
side is going to be a wherever our
camera is right now
Oh view X view right is 0 I could have
just set that to 0 to be like the
top-left corner of the room
but the reason I'm using this view and
the score X view 0 instead is so it
ranks where the camera happens to be if
you're using a camera moving around the
room otherwise by default if using if
you have in settled views um vo XP will
be still the top left corner of your
screen it's on X 2 is going to be the
right-hand side of the screen so it's
going to be the same as X 1 so wherever
our camera is now plus however wide our
viewport is so view W view for width 0
because it's camera number 0 Y 1 so the
top of our rectangle is just going to
beware of the camera is a view we're
going to score one view 0 y 2 is going
to be same as Y 1 to the top of the
screen
Plus like however tall we want this
rectangle to be I'm just going to say 64
community arbitrarily this stuff here
isn't that really important the
inventory system itself is just because
it'll change depending on how you want
to draw it this is just a simple way of
getting it on the screen it's going to
say draw set color to be black just
saying our drawing color to be black and
then set the transparency of our drawing
tool to be a not 0.82 like a little bit
spam I'm just going to draw rectangle x1
y1
yes y1 x2 and y2 for the next corners
you can see at the bottom those are the
ones that's asking for and then outline
it wants to know whether or not
filled rectangle or just an outline of a
rectangle we want a full rectangle so
that was not an outline so put zero in
there for outline and then set my
transparency back to lap so I mean I can
show that rectangle just working now if
I just pop into the room that I made and
just stick inventory in the middle it's
going to establish all those blank slots
for our inventory and I just going to
draw a blank rectangle top of the screen
or it's not because the inventory object
is marked as not visible I did tell you
guys tomorrow's invisible to start
I apologize go ahead and set that back
to visible it does need to be I close on
out run that again
and there you go black rectangle top of
the screen not much to look at yet but
we're getting there
so now that we're drawing this black
rectangle where we want our inventory to
be the next thing I'm going to do is use
a for-loop to draw the actual slots of
our inventory and draw any items that
happen to be in our inventory so I'm
going to say for again I equals 0 I less
than next items again so we're just
going to cycle from 0 up until the
maximum number of items can carry I plus
equal 1 the exact same cell for this
folding as we had before now in here the
first thing I'm going to do is for each
item I'm going to draw a border the
border sprite so draw a sprite sbr
underscore border and now for the
x-coordinate one I'm going to well
actually the sub image is going to be 0
um yeah there's only one frame of that
sprite
if the X&Y coordinate uh what I'm going
to do is I'm going to say uh use first
of all x1 I'm just going to use these
coordinates up here which determine
where the box is Plus 24 arbitrarily
just to space it out a little bit and
then what I'm going to do is add I x
Watty now what I've done there is I take
on whichever slot we're drawing so far
I'm using that x 40 to add to the
x-coordinate of where we're drawing each
one of these borders because this this
line of code here is going to be
repeated five times we're going to draw
this border in five times and we're
going to draw it in five different
places and the only thing that's
different every time this loop happens
is I increases by one so we can use that
multiplied by another value in this case
42 space out our borders along by
however much we put in here so these are
all going to be about 40 pixels apart
from one another the first one is going
to be placed at x1 plus 24 plus 0 times
40 so just x1 plus 24 then the next
one's going to put x1 plus 24 plus 1
times 40 then plus 2 times 4 8 then plus
3 and so on so forth and you can see how
it's going to space them out
horizontally over this blank box and
then vertically they can all be lined up
we're just drawing one row here so I'm
going to y2 minus 24 again
arbitrary value there's specific to this
rectangle but I've got up here it'll be
different depending on what you're doing
then the next thing I'm going to do is
check to see whether or not the I value
we're at is a slot in the inventory
where we have an item that Lee's drawing
because I'm gonna say if global dot
inventory and square brackets I so if
this specific slot of the inventory does
not equal minus 1 because as you know
before we set all of those slots to be
minus 1 when we made the object which
means that those slots are empty so if
they don't equal minus 1 it means they
have an item in them and we need to draw
it and then they draw sprite STR
underscore items and this is where the
sprite comes really n handy where each
frame of the sprite corresponds to a
different item of the game because now
all we have to do for the sub image or
frame that we want to draw the sprite is
just refer to
ever type of item is in this slot so in
sub image I'm just going right global
dot inventory and square bracket all
right so if it's not minus 1 that means
it's the value between like noir and 3
opal II so it's just going to take that
value and use that value to decide which
frame of SBR underscore items to draw in
the specific spot and then as for the
spot itself I can go ahead and copy the
the X&Y coordinate from where we drew
the border because it's going to be
exactly the same and then just close the
bracket on the end there
and that's that and that will draw that
will draw any items in our inventory
it's really that simple
there aren't any items in our inventory
yet but I can very quickly add one just
by going into our create event here and
after we sell all our inventory slots to
be blank in fact let me just show you
that like what it looks like when
they're all blank so you see now is
going to that for loop and is drawing 5
empty boxes here now if I go in and say
global dot in the pre um let's modify
slot 2 which will be the third one
technically because it starts at 0
let's take slot number 2 and set that to
equal what item should we use
we'll use the yellow key which is image
number 3 so I know as it says at the top
here so global dot inventory 2 equals 3
and that's so that means the third slot
of our inventory should have a ello key
in now if I run the game you can see
there it is little yellow key is
appeared in our inventory this is a
simple time you could use that to sort
of directly manipulate the inventory at
any time if you want to manipulate this
very specific slot or the inventory to
in be a specific thing all you need to
do at any point in the game is do global
dot inventory whatever slot number you
want to modify equals whatever item you
want it to be and that fundamentally
already gives you the power to
manipulate and control is in the drawing
but we're going to make things a little
bit easier to manage than that long run
so what we're going to do now is create
the tools necessary to add remove and
check for items in this inventory object
because this object by itself is
essentially done like that's all you
need to be to manage and control a very
basic inventory it's not honestly that
complex so the task
we've just created a list of variables
that will contain a number that
represents what type of item it is and
that's that's it you really and we're
just using that array of variables to
drawer items to the screen or and so on
so anyway the next thing we want to do
is going to create a series of scripts
but can add an item remove an item and
check for a night and as I said the
first time I'm going to create is going
to be SCR underscore item pickup
now what this script is going to do is
we're going to make it so that we can
write anywhere in the game or in any
object any code anywhere SCR underscore
item pickup and as you can see it's
turned yellow because it's recognize the
name of the script and then in brackets
whatever type of item we want to pick up
so if it was the yellow key for example
I'm three we can just write that
anywhere in code and it will add the
yellow key to our inventory that's what
we're going to do by creating the script
that's the OnStar and pickup so how the
scripts is going to work we're just
going to create another for loop using
exactly the same setup we used before
we'll use this one a lot throughout this
this tutorial for I equals 0 I less than
max items I plus equal 1
so in this for loop I'm going to see if
global dot inventory square brackets I
so if the specific slop is minus one
meaning this inventory slot is empty now
there's a comment it's what I is empty
right close bracket then global dot
inventory I going to take that slot and
say to be equal to argument zero now
argument zero
it represents the number that we put in
brackets whenever we call this script
when you create a script essentially
you're creating a custom command in game
maker that you can call from anywhere
else so if I go back to our inventory
object and if I was to type somewhere in
here at the top SCR on the sky and pick
up you see it turns yellow and then I
can open brackets and send variables
across to that script like at send over
for and I can put commas in and sound
like multiple variables across and then
after doing that when the script is
running it refers to those variables is
arguments 0 through like about 9 so if I
wrote argument 1 it would represent the
second number a fight wrote one bracket
comma 5 if I were argument 1 there it
would represent the number the second
number I wrote when calling the script
but we just want the first one there's
only one argument to the script just
argument 0 so we're going to set that
specific slot of the inventory to equal
whatever we sent the script then after
doing that script has succeeded at what
it needs to do is found the first
available slot because it's cycling from
0 all the way to 5 or all the way to 4
sorry so the very first free slot that
it comes across is going to set that um
that slot to be that item
then we don't want it to carry on the
loop otherwise it will fill up the whole
inventory of the signs and they say rip
turn one I'll buy return towels when you
might return in a script it ends to
script at at that point so if this
happens to be true that the slot is
three we add the item to the slot and
then we finish with the script now by
putting one in here uh it means the
script sends back a one to wherever it
came from so if I were to do um it means
we can set a variable to equal the
script and then the script will send
that one back to that variable so we
could say a test equal SCR underscore
item pick up a one for example o2 or you
know any any of the the item type so we
have in SP underscore ends and then as
assuming that works and it finds an open
slot puts the item in it the test is
going to be set to equal one because
it's going to the script is going to
return one and put that into who this
variable then if we cycle through all of
the slots in our inventory and we didn't
find any empty slots so our inventory is
full it means we're going to cycle all
the way through the for loop and come
after the for loop and say return zero
which will end the script after having
not put any items in any slots and we're
going to send a zero back now that just
the benefit of doing this returning one
returning zero means that when we add an
item we can say like add potion equals
SCR and Scott line pick up a two and
then say our if add potion equals zero
show a message saying the inventory is
full because if a potion is zero it
means that tried to run the script I
didn't find any available inventory
slots and therefore return to zero if it
equals one it means that it did find an
inventory slot and it did fill that slot
with inventory so then you can use that
to do other things in your game and say
like all the inventories for we couldn't
hide the items and so on so forth and
allow you to do things like that and
that's that for that script so that's
ser underscoring pickup now we can test
that out real quickly so at the moment
all our inventory items are blank I got
rid of the stuff we did earlier with the
key yep they're all blank but if in the
create event I'll object inventory now
at the bomb I stay SC arms for iron
pickup let's add the sword so I am 0 and
if I copy and paste that like 2 times so
like do that three times we should end
up with three swords in our inventory
yeah there they are three swords all
lined up in our inventory and now you
can use that script anywhere in your
game any game object or anything like
that um so that like or you could have a
sword on the floor for example and like
in the click event for that sword you
could just write ser and it's got item
pick up 0 and then instance destroy or
whatever and then that will add the
sword to your inventory simple as that
and and so on that's why we made the
script so that you can start actually do
things with this inventory the next
script I'm going to do is very very
similar STR underscore item drop uh this
script is going to say it's going to
start off with the exact same code as
before in fact I'm just going to write
copy and paste it from this
so this is the exact same code as the
item pick up script but instead of
checking to see if each slot is empty
and then adding the adding the argument
to that a slot I'm going to check to see
if the slot of the inventory contains
the item that we're looking for which is
argument 0 so we're going to look for a
specific type of item in the very first
one we come across we're going to remove
it from the inventory by setting that
slot to be minus 1 again and then if it
successfully does that return 1 if it
wasn't able to find the I in the
inventory return 0 really is as simple
as that it's not a slice empty anymore
if slot I
contains 1 0 so that's that one arm so
now we can see that one working if I go
back into object inventory if I add that
script again till I see our item pick up
um we'll do the blue potion I'm to will
do that like three times again so I'll
just run that so you can see three blue
potions in the inventory and then I'm
going to say ser I can drop to second
I'm is going to find the very first slot
with a blue potion app which will be
slot number 1 or 0 rather and it will
remove it from the image reset it back
to minus 1 so yeah we have like an empty
space here and then to blue potions
simple as that removing items from
inventory and then you can use that at
any point just as I explained with iron
pickup
now the last one we're going to do is
again almost the same SCR underscore
item Shack
now the script is going to check to see
if there is an item of the specific type
in the inventory so again same
thanks again I'm just going to copy it
again because it's almost identical I'm
going to go back tonight and pick up and
copy this paste it into this now we're
going to check every slot the inventory
just as before and say if that specific
slot equals the item we're we're looking
for just as we did with the item drop so
I can just say this again contains
argument 0 we're really this coat is the
identical to item drop both only instead
of removing the item from the inventory
we're just going to do nothing because
we don't want actually change the image
or in any way we're just looking to see
if this line in this there and if we do
find one of these items then we can
return one we found it returned one to
say that we found that and it will exit
the script at that point otherwise it'll
loop through each one the if statement
will never be true and it'll get all the
way out and we'll return 0 because it
couldn't find one and then all you would
have to do like if you were looking for
that item it's a potion rather sword
check our equals Ser underscore item
check 0 because sword a sword equals 0
and then if sword check equals 1 that
means we have sword so you can check
your inventory to see if you have a
sword by just doing sword check equals
Ser underscore item check 0 and if that
comes back 1 you do have a sword if it
comes back 0 it means you don't have a
sword in the inventory
simple as that so yeah with those three
basic scripts and the super simple
object and now I can um so yeah sorry 3
basic script super simple object you now
basically have everything you need to
create a simple versatile inventory
system you can hopefully modify and
expand upon to fit more or less any kind
of game with
inventory the Uni afore I'll cover some
more stuff for the inventory um a little
bit later involving like how to stack
items and how to make items contain
certain properties um like how to store
an items name description sprite and so
on rather than just just storing like a
number to represent the item but there's
a lot you can do that that really I'll
cover that a little bit later um but for
now there should be more than enough to
get you going with basic inventory
systems one last thing just to show off
the I have the system kind of working in
real time as opposed to just doing it on
the create event is I'm just going to
add the keyboard like the P the P key so
one of the P key is pressed in fact I
won't keep press with this letter P so
whenever I press the P key I'm going to
add a potion to the inventory just to
demonstrate how this would work now what
I could do is just do I see our item
pick up two and that will work so now if
I run the game now press P I can fill up
the inventory oceans super simple but I
want to add something just to check to
see whether or not um the inventory is
full when I try to add the potion so
that I might you know know not to
destroy the potion I clicked on on the
floor or etc so I'm gonna say var and
potions temporary variable add potion
equals SCR underscore iron pick up - so
I'm setting this variable to equal the
result of this script which is going to
be 1 or 0 depending on if it works or
not if add ocean equals zero then we
know that the inventory
is full and so whatever you would want
to do in here maybe you'd want to show a
message on the screen or you just avoid
destroy maybe you want to check to see
if it did work and if it did work Oh
destroy potion item that you just
clicked on on the floor so on so forth
but yeah that is that at the end of the
day that to two simple events and one
object and three scripts to help you
manage it that is the basics of how you
do an inventory system and also just how
you use arrays at a basic level hope you
guys enjoyed that more coming on this
little stuff soon and I'll catch you
guys next time thanks for watching see
you next time guys
you
