C# Monogame RPG Made Easy Tutorial 23 - Loading Our Map Video Lecture | Monogame Tutorial: Design your own Game - Game Development

caught up babe yo what's up everybody
and welcome to your next c-sharp Margie
Margie tutorial and this tutorial we are
going to be learning how to load our map
and I said the last tutorial was
supposed to be short but it was longer
than expected just because of unexpected
simple errors um but uh we will get to
that later
um I said that we were gonna have like
three or four more tutorials but maybe
be a bit long a bit more
I just want to split them up into
shorter tutorials because the long
tutorials end up getting a bit boring
after a while
so I'll try and make these tutorials as
short as possible and hopefully you your
grasp it a lot better so what we want to
do is you want to go to our designer and
we want to double click load lap so we
actually want to load it now and so we
have something called open file dialog
and will say I will use the same thing
and we could say or the filter just like
we have above here so we're going to do
is we're just going to copy this filter
paste it in there and we're going to set
the title to load map and when we load
our map we actually want to load in the
Maps content so this is how we're going
to do it we are going to go to the map
class or sorry the editor class and I
will just make a will make a set method
for this as well as we'll say map equals
to value
and I will do is we go back to four
months es and we'll say F or F D dot
show dialogue equals and we do the exact
same thing so once they select a file
link okay we need to know what to do
with this file and so we're going to
make a call to external sterilizer but
we have to include the namespace sorry
and we need to include system IO
so what we're going to do is we're going
to say XML serialize and we're going to
make a civilizer instance and we need to
we need to get the type tool say a map
that get type so we are going to say XML
or we're going to say editor one dot map
is equal to XML dot deserialize and we
want to serialize the writer but first
of all sorry we should be doing this in
a using statement so we're going to let
us say stream reader that's a writer
before I think I might read it I think I
said writer by my reader and we're going
to be passing in off D the open file
dialogs filename and we're going to be
saying every one dot map
dot is equal to XML deserialize and
we're going to deserialize the reader
and that's going to deserialize the uh
oh yeah and i got a cast it sorry
so i may get a map type and uh so uh you
might be thinking okay this is enough
that's fine but what's happening is not
we're not going to see any changes to
our code because when we actually load
in our map um we know our layer and
stuff we convert a layer stuff to our
tile map up to our time our vector of
tal maps or vector tiles or whatever so
we have to do is we're going to have to
where to initialize we're going to have
to initialize this all over again so
that a converts everything and so
everything is the same
so how are we going to go about this
well we'll just make a call to
initialize so where's form dots yes
editor one dot map dot initialize and
we've got to send it a a Content Manager
which we do not have at the moment so
what we're going to do is we will um we
will get the editors Content Manager
sorry
so we'll say public Content Manager get
returned content and so we're going to
go back to our form right here will say
editor one dot content and voila
so that should initialize our map and
everything should run smoothly hopefully
and we've got an error so saying object
reference not set to an object and so
the tile display again um every single
time I think it rebuilds if we go back
to our designer we view the code
yeah for some reason it keeps on
changing to the default constructor and
that's why I didn't have it in the first
place so I'm not sure if you're gonna
have to keep doing this I'll see if I
have a fix for it um but for now we'll
just put that in there again and so
we're just going to make a call to load
map and we're load map - and voila our
map - is loaded in so now you can edit
you can save this you can save it or if
you're if you don't like it you can just
reload the old map and voila we got
loading and saving in our program so I'm
going to try and see effects I haven't
I'm not the greatest with c-sharp and
the WinForms so if you know the fix for
it then just let me know
um and I will try and search for one and
if I can't find one then I will just
keep on doing this it's not too much
hassle but thanks for watching don't
