C# Monogame RPG Made Easy Tutorial 3 - Xml Serialization Video Lecture | Monogame Tutorial: Design your own Game - Game Development

caught up babe so what's up everybody
and welcome to your third c-sharp mano
game RPG tutorial and then this tutorial
we are going to be doing some XML
serialization and if you guys have never
done XML serialization before this is
pretty cool and if you have done it
before then it's still pretty cool I
don't know but uh yeah let's just get
started
so in this tutorial I'm gonna be just
getting the code done and in the next
tutorial I'm going to be getting in
depth into some XML serialization topics
since I've never taught it in any one of
my tutorials so anyways let's get
started oh I'm gonna name this class XML
Manager I don't really care what you
want to call it but this is where we're
going to be doing this serialization now
the class is going to be a generic class
type meaning that we can define the type
of it once we declare it add those two
namespaces that we want to include
there's an XML serialization namespace
and there's the input/output namespace
so firstly we want to have a variable
called type that will have a public get
and that private set and we are going to
have a load method that's going to
return type a generic type
and we're going to make a we're going to
use a text reader to open up a stream
reader and we're going to pass in the
past now within this scope we're going
to make an instance variable of whatever
type that we have and then we are going
to make a XML serialization else
utilizar variable and we're going to
pass in our type okay and last but not
least we're going to make a call - we're
going to say instance is equal to xml
deserialize and our stream is the reader
last but not least we will return the
instance and we are done so doesn't
really look like we're done so this has
to go outside and either I'm missing
something or I'm missing something
uh so Oh
exactly so we got to convert it to a
type T - whatever generic type that
we've had so we're also going to use
this save method we're not going to be
using this anytime soon but might as
well implement it now and in this save
method we're going to be using the text
writer this time color right into a file
I will call this writer and we're going
to do it to a stream writer and we're
going to pass in the past
okay so in here we're gonna make a XML
serializer instance I would before and
we're going to pass in a type and we are
going to call the XML serialize and
we're going to serialize the writer
there and we're going to pass in the
object so we got to take in one more
parameter call object and we'll call it
okay okay so that's simple enough and
what this is really gonna do is that
what with the load we're gonna take this
stuff from our XML file we're going to
load it in and for the save we're going
to save our classes or whatever back
into an XML file so with that being said
let us see it in action
now I stated in the last tutorial that
this has significance and we're going to
see it in action right now so we're
going to make it public so we're going
to change this to an upper case and we
don't need this anymore so what we're
gonna do is we're gonna load we're
actually going to load the path from an
XML file so what what I'm going to do is
I'm going to create a new folder and I'm
gonna call this load and I'm going to
add a none brand new XML file so scroll
all the way down to XML file and let's
call this XML file splash screen splash
screen okay so in here we're gonna put
splash screen and we're going to put
path and the path is going to be splash
screen dot slash image 1 and if you guys
have no idea of what XML serialization
is about don't worry it's all going to
be explained in the next tutorial so
what you want to do is that lishus get
the code done so I it'll be easier to
explain in the next tutorial so now I've
gotten that done we're gonna pass the
path into here and
we're going to draw like so so to start
things off what we have to do in our
screen manager is for current screen we
have to actually load it load in some
stuff so what we're going to do is make
a call to XML manager I'm gonna pass in
game screen I'm gonna call I'm gonna
name it
XML game screen manager and inch in here
I will say ah the type is going to be
equal to our current screens tight so in
order to get that what we're going to do
is we're going to go to our game screen
and we're going to create a constructor
and we're going to have a type variable
public type and let's just put XML
ignore there
so we gotta include the serialization
namespace so we've gotten that done and
we're going to say type is equal to this
get tight okay so that's simple enough
so what that's going to do is that
whatever class we have is going to pass
in that type to it so that's pretty much
self-explanatory so what we have to do
now is go back to the screen manager so
what our current screens type is of is a
splash screen type so what we're going
to do is we're going to say XML game
screen managers equals new and we'll say
the type is equal to current screen dot
type so it's going to be set to that and
we're going to say current screen is
equal to XML manager load and we're
going to load our splash screen XML so
that is setup and oh yeah we never put a
set accessor so what we're gonna do is
we'll just make it get set or just make
a public okay so now that we've gotten
that setup we're going to load XML
contents Lotus's current screen and we
should see the exact same images as we
saw last tutorial but sadly we don't and
the reason being is that our output pass
is different than our regular path and
what we want to do is go to our project
and properties we want to go to build
and just make our output path the same
as our regular path so we can get rid of
that and we can run this again and voila
we got the same thing so the difference
is that instead of us having to place a
path we loaded the path from the XML
file now I'm not sure if you've got to
gather the gist of XML serialization but
there's still other things that I have
to explain to you which I will explain
the next
toriel if you are a newbie to XML
civilization XML serialization is fairly
simple you should be able to get a firm
grasp on it with just one tutorial so
I'm looking forward to the next tutorial
to really show you guys it just a bit I
hope you guys really enjoyed this
tutorial I hope you guys I just took a
little something from it and after the
next tutorial everything will be
clarified and then we'll get on to newer
and better things in the next few
tutorials so that's it for now hope you
enjoyed it don't forget to comment rate

and bye for now
