C# Monogame RPG Made Easy Tutorial 1 - Introduction Video Lecture | Monogame Tutorial: Design your own Game - Game Development

baby what's up everybody and welcome to
a brand new tutorial series so let's go
so in this tutorial series we are going
to be developing an RPG from ground up
using c-sharp and monnel game so what
what this means is that we're going to
be using X in a four-point-oh to develop
the code and when it comes out a
workable state what we're gonna do is
we're gonna pour it from XNA to mono
games so we can port it to Linux Windows
8 Windows Phone booyah
Android whatever console you wanna
distribute it to that menu is that mono
game supports even iOS so to tortures is
gonna be really fun we're gonna develop
a town map editor from ground up I've
never developed a town map editor in
years so it's a learning experience for
me as well but I hope you guys really
enjoyed this tutorial series I hope you
gained a lot from it and I'm gonna be
trying to explain everything as simple
as I can now note that this is I'm gonna
try and make it as beginner friendly as
possible but there is a level of
knowledge of see sure that you should
know you should have a good working
knowledge of c-sharp and you should have
a good working knowledge of XNA if you
don't have a working knowledge of
either/or then you can always watch my
tutorial series and if you want if you
want to learn about XNA then you can
always watch my tutorial series on X
name so now let us get right into it
enough talking let us finally start iron
our first RPG project and I hope you
guys are excited cuz gonna be really fun
okay so what we want to do is remember
we're gonna be using an ex named project
so we want to select Windows game and
I'm just gonna call this YouTube RPG so
you can say no there okay so we already
know what this stuff does so we're gonna
forget about that and we're gonna be
adding in three or actually one class
right now just not to confuse us and
we're gonna be adding in a few
namespaces so we're gonna add the
default namespace we're gonna add in the
content name face and last but not least
we're gonna add in the graphics
namespace so what the screen manager is
going to do the screen manager is gonna
be used to manage all our screens so
it's gonna load everything we need on
our screen current screen it's gonna
unload everything on the current screen
it's gonna update everything on our
current screen and it's gonna draw
everything now for some people you guys
are like what is the screen manager what
does it do what is its ultimate purpose
and I'm gonna explain to you its
ultimate purpose so be ready to be
mesmerised or wherever anyways so the
screen manager everything is gonna be
divided up into screens if you notice
whenever you play a game and you insert
a game let's say Call of Duty or
whatever you'll see a splash screen of
different companies that it helped like
you'll see like Treyarch or I don't know
if Activision does anything or you see a
some Activision or something else so I
don't know all the game companies out
there I'm sorry but basically you will
see of all the companies or whatever who
had a part in it and that is called a
splash screen and after that you'll go
to an like the title screen and then
after that you'll go into the game play
screen if you have options you have an
option screen if you have dev credits it
shows the credits screen and there's a
bunch of different screens that make up
this one huge game and so what we're
gonna do is we're gonna divide up our
game into a bunch of different screens
and that is ultimately gonna give us the
perfect all after
oriented programming experience I
shouldn't say perfect
there's alternate ways to go about it
there might be better ways maybe worse
ways but this is a very efficient
effective way to go about it so now
we're gonna do is we're gonna start off
by creating a load content method now as
you can probably guess the low content
method loads and content simple enough
so what this method is gonna be used for
so loading game content from DQ from the
content section such as sprites such as
images certain things like that and
we'll get more depth into that later
secondly we'll have a unload content
method this will unload everything when
we don't need it okay simple enough the
reason why we have a ton low content is
that we don't wanna if we want a current
screen let's say we're on the title
screen and we're done with the splash
screen why do we still need the splash
screen elements in memory it makes no
sense whatsoever it's using up space on
the hardware which it doesn't need to
use up so we can free it on our own
even though c-sharp is the object
oriented language sometimes sometimes we
have to free stuff on our own and what
we're gonna do is we're gonna create a
update method which is I'm gonna update
game elements I'm pretty sure that's
self-explanatory and we are going to
make a draw method and this draw method
is going to draw everything to the
screen again this is self explanatory
now before I end this tutorial we want
the screen manager class to be what is
known as a singleton class now a
singleton class is called a singleton
because we want to have a single
instance of the class so a singleton is
sort of like a static class but it is
more efficient now if you search of
singleton classes on Google you will see
a lot of people bashing it now singleton
can have a lot of negatives if you don't
know how to use it properly but if you
use it in the correct fashion it can
have a lot of advantages and you'll see
a lot of advantages in just a moment so
what we're gonna do is we're gonna make
a public static screen manager instance
and we're gonna make a property called
screen manager we're gonna call it
instant sorry and it's gonna have a get
accessor a no set accessor and in here
we're gonna see that if instance is
equal to no then instance is equal to a
screen manager instance else or there's
no out sorry otherwise we will return
the instance so what is go sorry this
should be new sorry so what's gonna
happen is we're gonna access all of
these methods through this instance
property so what we're gonna do is we're
gonna call the instance property if
there's no if nothing is created for
this yet then it's gonna create a new
schema and for instance otherwise it's
still just gonna return the instance and
therefore we can do various things and
this might confuse you so I'm gonna show
you this in action right now so what
we're gonna do is we're gonna make a
vector two called dimensions and I want
to make it we'll make it a private set
and a public get okay and what we're
gonna do is we're gonna go to our game
one CS so we have a load content unload
content update and draw just like these
methods here so what we're gonna do is
gonna make a call to screen manager dot
instance dot load content packs in the
Content Manager now you see how easy it
is it's kind of like as global it's kind
of like a static class but it has its
uses so you were gonna say screen
manager instance don't unload content
and we're good we're calling screen
manager instance
update and last but not least we're
calling screen manager dot instance dot
draw so what's what's is doing when we
call screen manager dot instance
remember that our instance our instance
property is static so we can call it
like that so what we call screen manager
dot instance it's gonna return this
right and what instance is is a instance
of our screen manager so we're gonna do
is we're gonna be able to call load
content load content basically anything
that is public so that is essentially
how it's working now before the tutorial
ends we're gonna make a call to screen
manager no actually yeah what we're
gonna do is we're going to make our our
constructor and in our constructor we
are going to set dimensions equal to
whatever screen size you want it now I
believe by default it is 640 by 480 but
we still want to set it like this
because there's other things later on in
our code which is gonna depend on the
width and height of the screen itself so
what we're gonna do is we're gonna say
graphics in the initialize method we're
gonna say graphics top preferred
backward for width is equal to int green
manager dot instance the dimensions dot
X graphics top preferred backwards
buffer height it's gonna be equal to
scream energy dot instance dimensions
dot y and then we're going to take
graphics don't apply changes so since we
change the screens width and height I'm
not sure if we changed it or not but
just to be on the safe side this is
gonna change the screen width in the
height to whatever width and height that
we specify so that is it for this
tutorial nothing is gonna change in the
game window but I hope you enjoyed this
thanks for watching in the next tutorial
we're gonna
get something up and running so don't
forget to count rate subscribe and bye
for now
