Hi,

I want to trigger an animation(tk2d Animated Sprite) also I have a shaman and gold on screen.When gold touched a shaman, gold is destroyed but I can't see animation.I want to gold touched a shaman, gold is destroy and "golddestroy" animation.

I take it my shaman object is "goldshaman" tag and animated sprite,shaman and gold has a sphere collider and trigger is a selected. I take a one error. Error is a " NullReferenceException: Object reference not set to an instance of an object"

Here is the code:

public class col : MonoBehaviour {

 tk2dAnimatedSprite animSprite;

// Use this for initialization void Start () {

     animSprite = GetComponent<tk2dAnimatedSprite>();

}

// Update is called once per frame void Update () {

}

 void OnTriggerEnter(Collider collision)
 {

     if (collision.gameObject.tag == "goldshaman")
     {

         animSprite.Play("golddestroy");

     }
 }

}

Please help me Thank you :)

When posting code, please click the code button ("101 / 010") first. It makes the code more readable.

The NullReferenceException probably means animSprite is null.

Whenever you try to get a reference to something, check its value afterwards. Change your Start() method to this:

 void Start () {
     animSprite = GetComponent<tk2dAnimatedSprite>();
     if (animSprite == null) {
         Debug.LogError("Did not find tk2dAnimatedSprite on " + gameObject.name);
     }
 }

If you get the message "Did not find tk2dAnimationSprite...", then you need to make sure there's a tk2dAnimatedSprite on the game object. Otherwise you can't play an animation on it.
