I've looked at that, I guess I was to aggravated to actually sit down and look at all the code.
Thanks,
EpicAsian
Edit:
So, in XNA, The sprite sheets are just a lot of different, single image files?
I'm used to loading in one file with many sprites on it (SDL).

You basically have one image with many sprites on it(Spritesheet). From there you have to locate within the spritesheet the individual sprite you want to draw.
First you add the spritesheet image to your project.
You then load the spritesheet into a 2D texture.
Then you can setup rectangles for the individual sprites you need.
Finally you use the rectangles that you created in your calls to the draw function.
This is at least what I've learned so far in my study of XNA.

^This is the basic idea of it. I'll try go into a bit more detail:
Code: Select all
spritebatch.Draw(texture,
position,
new Rectangle(currentFrame.X * frameSize.X,
currentFrame.Y * frameSize.Y,
frameSize.X, frameSize.Y),
Color.White, 0, Vector2.Zero,
1f, SpriteEffects.None, 0);
the section you should be concerned with is the third parameter.
Code: Select all
new Rectangle(currentFrame.X * frameSize.X,
currentFrame.Y * frameSize.Y,
frameSize.X, frameSize.Y),
This finds the current frame in the tilesheet. You need two Vector2's currentFrame(to hold the position of the frame on the tilesheet eg 0,0 is the first frame starting at the top left corner) and frameSize(which holds the size of each frame eg if the sheet was full of 32x32pixel tiles then frameSize would hold 32, 32).
