How can i play MovieTextures of Prefab instances independently?

Question

I got multiple instances of a prefab on Stage each using a MovieTexture which plays when the instance gets hit. My problem is that the MovieTexture is not playing independently from the other instances MovieTexture. So when one instance gets hit all instances play the texture. Is there a way to play the MovieTexture of an instance independently from the other instances?

In the prefab script i store the two Materials (hit & default Material) to switch between them on collision. Now when every instance was hit, the MovieTexture plays not only in the instance which was hit. How do i independently play the MovieTexture of the instance?

Script of the prefab:

public var hitMaterial : Material; public var defMaterial : Material;

function Start() { this.gameObject.renderer.material = defMaterial; }

function OnCollisionEnter (collision : Collision) { 
 if (collision.gameObject.name == "PlayBall") ReflectObject(collision.gameObject); }

function ReflectObject(other : GameObject) { this.gameObject.renderer.material = hitMaterial; this.gameObject.renderer.material.mainTexture.Stop(); this.gameObject.renderer.material.mainTexture.Play(); }

I think what you need to do is define one material for each game object that should play a different video. You can then assign these different materials and it should work. For testing, you could start with just 2 objects and 2 materials (I haven't tested this myself, and there might be a better solution).

I tried this already and it doesnt work. As soon as the material uses the same Video as Texture the video is playing simultaneously on every texture which is using it! The only solution i got was to remove the $$anonymous$$ovieTexture after 1sec so that the video is not visible on the other instances. The other way is to duplicate the video before compiling and adding it to a different material. But this dont work because i dont know how many instances will be on stage. It seems that the video is saved in memory an projected to every $$anonymous$$aterial which is using it?! Thanks anyway!

Ah, interesting point ... but what you should be able to do is create copies of the movie "on-the-fly" while the game is playing. That should hopefully then finally fix it.

Ah ok! How would you do that? Instantiate the $$anonymous$$ovie or which command is useful in this case?

Got it. I need to instantiate the Movie itself and add it to the current Texture. Thanks Jashan for the hint!

Here he working code: (texMovie is the Movie attached to the prefab)

public var texMovie : MovieTexture; private var cloneMovieTexture : MovieTexture;

function Start() { cloneMovieTexture = Instantiate(texMovie); }

function OnCollisionEnter (collision : Collision) { 
 if (collision.gameObject.name == "PlayBall") ReflectObject(collision.gameObject); }

function ReflectObject(other : GameObject) { 
 this.gameObject.renderer.material.SetTexture("_MainTex", cloneMovieTexture); this.gameObject.renderer.material.SetTexture("_LightMap", cloneMovieTexture);

 this.gameObject.renderer.material.mainTexture.Stop();
 this.gameObject.renderer.material.mainTexture.Play();

}
