Getting access to the spriteanimation from a trigger event

[k3ch0ng]

Hi, how would I get the sprite to play a new animation once a trigger event occurs ?

e.g. my character collects stars, i want the stars to sparkle then vanish ( the trigger code is within the charcter )

   public void OnTriggerEnter(Collider trigger)
   {
      switch (trigger.gameObject.name)
      {
          case "pfWall":
         break;

          case "pfStar":
         
             trigger.gameObject......
         
             break
      }
   }

You need to get the tk2dAnimatedSprite component.
tk2dAnimatedSprite sprite = trigger.gameObject.GetComponent<tk2dAnimatedSprite>();
sprite.Play(...)

If you need it to sparkle and then vanish, I suggest using a coroutine to play the animation, wait until it finishes, and then disable the gameObject. Something like this...

Code: [Select]

IEnumerator PlayStarAnimationAndVanish(GameObject target)
{
tk2dAnimatedSprite sprite = target.GetComponent<tk2dAnimatedSprite>();
sprite.Play("animation");
while (sprite.isPlaying())
{
yield return 0;
}

target.active = false;
}

and in your code,
StartCoroutine(PlayStarAnimationAndVanish(trigger.gameObject);

Also don't forget that you probably want to inhibit collisions as soon as the animation has started playing, as it will keep triggering again and again - you can do this by setting the collider to "none" on the frames of animation, or simply coding it in the coroutine above.

Hope that helps,

Thanks that help alot.

To detect if the animation has stopped i just raise another event. Is this a good idea ? Also anyway to get what the animation string is rather than the index ?

                tk2dAnimatedSprite animSprite = trigger.GetComponent<tk2dAnimatedSprite>();
                animSprite.Play("sparkle");
                animSprite.animationCompleteDelegate = SparkleFinish;

    private void SparkleFinish(tk2dAnimatedSprite sprite, int n)
    {
        sprite.renderer.enabled = false;
        Destroy(sprite.gameObject);
    }

Using another event is fine, too.

You can get the animation name by doing
animSprite.CurrentClip.name
