Animations

Let's make our Sprite animate when walking

• Open the file player.gbr with Game Boy Tile Designer (you should associate the extension *.gbr to be always opened whit this program if you haven't done it yet)
• Change the aspect of the Sprite by a boy and add a couple of frames for the walking animation. Something like this

• Save your file (do not export! ZGB will take care of this stuff now)
• If you Build the project now you should see the new Sprite instead of the Game Boy
• Animations are declared as arrays of UINT8, the first value is the number of frames. Declare the next arrays on SpritePlayer.c

const UINT8 anim_idle[] = {1, 0}; //The first number indicates the number of frames
const UINT8 anim_walk[] = {2, 1, 2};

• And now you can animate your character like this:

void UPDATE() {
	if(KEY_PRESSED(J_UP)) {
		THIS->y --;
		SetSpriteAnim(THIS, anim_walk, 15);
	} 
	if(KEY_PRESSED(J_DOWN)) {
		THIS->y ++;
		SetSpriteAnim(THIS, anim_walk, 15);
	}
	if(KEY_PRESSED(J_LEFT)) {
		THIS->x --;
		SetSpriteAnim(THIS, anim_walk, 15);
	}
	if(KEY_PRESSED(J_RIGHT)) {
		THIS->x ++;
		SetSpriteAnim(THIS, anim_walk, 15);
	}
	if(keys == 0) {
		SetSpriteAnim(THIS, anim_idle, 15);
	}
}
