using a projector to place a animated image on a terrain

Given you want to swap images on the projectors material, here's how I tried this out. Put it on the projector. Make sure you use the appropriate projector shader.

public class AnimatedProjector : MonoBehaviour { public float fps = 30.0f; public Texture2D[] frames;

 private int frameIndex;
 private Projector projector;

 void Start()
 {
     projector = GetComponent<Projector>();
     NextFrame();
     InvokeRepeating("NextFrame", 1 / fps, 1 / fps);
 }

 void NextFrame()
 {
     projector.material.SetTexture("_ShadowTex", frames[frameIndex]);
     frameIndex = (frameIndex + 1) % frames.Length;
 }

• As a side note: I had a hard time tweaking my material so it wouldn't look dodgy on the terrain. In case you experience blocky terrain where the projector shoots, try fixing your material shader (projector shader) and make sure your textures are set to clamp.
