Tiled RPG - Sprites

Newbie & Debugging Questions
#1

Hey on a tiled map rpg for my sprite of my player insted of having one image for,let’s say U.p and Another for Down.how would I use 1 spritesheet for all positions rather then one .png image for each position of the player? Am I able to do this? I’m guessing I would load only part of the image at a time using X,Ys. But I really have no idea. I’m brand new to java game dev. And am looking for some help.
Example of source code(that has been explained) would be helpful.

Thanks for reading,
Keith M.

If you’re doing a top-down game (like GTA II) where your sprite is the same in all directions, you only have to rotate the sprite accordingly to the direction you’re moving.

#3

Or you could go Old style and make these
L
UL
UR
R
DR
DL
D
U

U = up
L = left
R = right
D = down

#4

But do I use one sprite sheet? Or do u break the sprite sheet into the diffrent directions? Making up.png,down.png,left.png ex.

#5

Use one sprite sheet

You should use one spritesheet, and then you would use the getSubimage(int, int, int, int) method of BufferedImage to obtain all the images.
Depending on how you set up your spritesheet, you could probably get away with using a loop and storing the images in an array. eg:


final int WIDTH = 32;
final int HEIGHT = 32;

BufferedImage spritesheet;

BufferedImage[] sprite = new BufferedImage[10] // Say there are 10 images you want to load from the spritesheet

private void initImages()
{
   for( int i = 0; i < sprite.length; i++)
   {
      sprite[i] = spritesheet.getSubimage(i * WIDTH, i * HEIGHT, WIDTH, HEIGHT);
   }
}

That should work, then you simply need to draw the spite.
