1 Creating Weapons in Minutes (Unity3d & WeaponControl) Video Lecture | How to make Video Games: Game Editor Tutorial - Game Development

in this little series of videos I'll
show you how to create new weapons from
your 3d modeling application into unity
until they are functional weapons inside
of FPS control absolutely without
writing any line of code because we have
already done that hard work for you so
this going to be pretty exciting let's
get started if I go to the FS control
assets folder and then enter the art
packs that we've supplied for you and I
need to shellshock des guns which it
holds all the guns that we've supplied
then you'll see that there are two
weapons in here one of them is the hands
with the beretta and the other one is
the m16 now these are FBX files they're
exported outside of 3d studio max and
you know they had the animation done an
all in one timeline so what we had to do
here at the animations tab is split all
the animations up sort of unity knows
what the difference is now you may not
have to do that for example you can also
save the animations under the same name
but then in the file name and an add
symbol and then the name of the
animation so that you have one for each
one file for each animation and then
unity will automatically already assign
it if you don't want to do things in one
timeline but in this case the file was
set up that way now you don't
necessarily have to use FBX files it is
probably the best thing to do though but
if you're for example will use my our
blender or 3d studio max you can just
move those files in here just by
dragging and dropping them together with
their textures when unity will run my or
Max or what have you in the background
and export it to FBX for you however if
you then share your entire project with
somebody else on your team and they
don't have that software installed it
won't it won't import it right so you
may as well export this FBX and use that
convention at least that's what we do
okay so if I open this up here with
little triangle and if you don't see the
assets this way you may be in one column
layout so I'm going to go to the two
column layout here and if I hit a little
triangle it opens up and shows us all
the assets that has imported from this
fps or I'm sorry FBX model so there are
a couple
and there are a couple animations so
here are all the animations that I need
however when it imports it it says these
are the animations that come with the
file so you cannot change them they are
read-only not right and we have to do
some writing to these animations in a
little while so we may have to come up
with a little fix here so I'm going to
right-click and create a new folder and
call that m16 names for animations then
I'm going to select all of these and
then go edit duplicate and that will
create a copy of these animations and
those are writable so I'm going to drag
those into the m16 animation folder now
if I go into that folder you can see
that all your animations start there
let's go back up let's grab this m16
here and drag it into the scene of
course we need this parent object we
don't need all the the subs because we
don't want to separate them from each
other
however the animations that are defined
in here are still the ones that come in
by default so I'm going to go to my m16
folder and replace them so activate here
and change my idols so the reason I'm
doing this is because we need to add
some magic to it eventually so we're not
going to do that in this video yet
because we have some other things to do
first but it is very important because
we need to specify in the engine when
the particles start when the gun fires
for example those type of things
so we need to know and we need to define
that inside of the animation itself and
that is why they need to be writable
where's my run here's my run and sprint
excellent and then deactivate finally
all right cool
so that replaced everything in the
animations so if I go to my animation
tab here and if you don't have it you
can switch to it by coming down here and
choosing add tab animation and I can I
can see that I have forgotten just one
to activate one because it's read-only
so I need to go fix that and that's
probably the stop on here that's the one
that I forgot okay so there's the double
check I've done it right now you can see
that all the animations are not
read-only so I could write to them okay
that's cool next we need to make sure
that our player recognizes this mash and
animation as a weapon so this will be
the perfect time to explain how the
weapons system is organized inside of
FPS control if I go over here to the
right into the player and I open it up I
go to its upper body then I go into the
main camera and then I see a little
empty placeholder here that's called
weapons and underneath weapons we will
have all the weapons now in this case
there's only one app weapon added and
that's the beretta but we want to add
multiples there so that's what we need
to do however we cannot add this 3d mesh
all at once we need to do a little bit
of work first so first go up and say
game object and create an empty one so
this creates an empty game object in the
scene I can move it around you know and
it doesn't have anything other than a
position what I'm going to do is going
to drag that game object underneath
weapons and so now it is officially a
weapon although it's empty
however it's not positioned right so go
up to the right here toggle this button
and click reset and that resets it and
moves it exactly on the position that
the player is or its parent object which
in this case is the weapons so then I'm
going to rename it and call it m16
excellent this object is still empty of
course so we're going to grab our m16
model that we've rigged up all
diligently with our animations and drag
that on top of the m16 then we're going
to select it and reset the position of
that one as well and there you have it
now it's part of the player if I go to
game view you can see it's kind of
blocking our view so we could change
that by you know moving it up or down
just a little bit see no no it's really
not helping so maybe it down a little
bit more excellent so this this arm here
was already there for two for the
Beretta you could do the same for that
but first now let's get a good overview
of what's gonna happen next okay so
that's working now I'm going to grab the
m16 and I'm going to do something you
probably not expect let's go to our
project let's go back out of the art
assets and go into the prefabs folder
and then the weapons folder then I'm
going to drag this m16 in there so that
it becomes a prefab so that we can reuse
it later and you can see that it turned
blue into the editor which means it's a
prefab now but now we're going to do
something crazy we're going to select it
and delete it command backspace or
command delete on Mac or delete key on
Windows you're asking why are we
deleting it we spend all this time you
know rigging it up well that was only
for the positioning the rest of it is
done by the magic of FPS control and it
adds all kinds of cool stuff to it so
that is what we'll do next in the next
video so it's really going to be fun
from here on now we've done the prep
work but next we're going to just assign
it as a functional weapon it's going to
recognize automatically all the
animations and we're gonna add particle
effects and sounds and all that good
stuff so see you in the next video
