How can we achieve animations in playN

Question

I need to create some simple effects for the layers which I have created in my playN game. For instance, a layer starts as a line, resize on update, and thus slowly expands to full screen. Can I use triple play for this? For example: we can use setAlpha in update function to make a fading effect.

Answer 1

check out the Animator class from tripleplay, does exactly that

code snippet:

class MyGame extends Game {
    private Animator anim;
    private float _elapsed = 0;

    public void init() {
        anim = Animator.create();

        anim.tweenScale(aLayer).from(0).to(50).linear();
    }

    public void paint(float alpha) {
        anim.update(_elapsed + alpha * updateRate());
    }

    public void update(float delta) {
        _elapsed += delta;
    }
}
