Spriter Integration

Let's suppose you have created some animations for a character in Spriter, and you want to use this animation in your game.

There are a pretty straight forward process to make this happen!

First, create a folder in the assets folder, that will contain your project (the images, and the .scml file)

The class responsible for creating a Spriter Animation GameObject is the SpriterAnimation, so you can instance it on your player class, like this:

public class Personagem extends PlatformPlayer{

	SpriterAnimation animation;
		
	public Personagem(ObjectInfo info, MapProperties properties) {
		super(info, properties);
				
		animation = new SpriterAnimation(info, "spriter/proj.scml", new Vector2(get("x", Float.class) / State.PHYS_SCALE, get("y", Float.class) / State.PHYS_SCALE));
		getState().putInScene(animation);
		
		setJumpStrength(10);
		setSpeed(5);
	}

	public boolean update(float delta) {
		super.update(delta);
		animation.getTransform().setPosition(
				body.getWorldCenter().x,
				body.getWorldCenter().y); //Here you can apply some offset if the sprite isnt fully aligned with the body
		animation.setScale(new Vector2(1/4f, 1/4f)); //you can also scale up or down
		animation.flip(direction == -1, false); //and flip in the x or y axis
        }

This will render your animation with the default animation that is set on the Spriter Project

To change animations, you can simply call the method:

animation.setAnimation(animationName);

You can also make composed animations based on two animations. To do that you actually pass a Player object (not the one you created, the Player class that already exists within Spriter library) that has the interpolation information. To create a player that is the interpolation of two animations, use the method:

animation.setPlayer(animation.createInterpolatedAnimation(String animationName1, String animationName2, float alpha));

and set the player with:

animation.setPlayer(Player anim);

You can do this if you want to, for example, interpolate between a Walk animation and an Idle animation, so the player can smoothly transition between the idle and Walk animation when walking:

That's it for Spriter Animations! If you want to learn how can you manage animations with an animation controller go to the Animation Controlling page!
