[Solved] Prefab Instance Communication with other GameObjects

So, I'm stuck implementing a little puzzle mechanic, but for the sake of brevity I'll only explain the issue I've identified. I use the Material mat of my Gun Controller gc to swap r.material and rHit.material.

Code (CSharp):

1. Renderer rHit = hit.collider.gameObject.GetComponent<Renderer>();
2. gc.mat = rHit.sharedMaterial;
3. rHit.material = r.sharedMaterial;
4. if (hits < 1){
5.     Destroy(gameObject);
6.     return;
7. }
8. r.material = gc.mat;

Assigning a material to the gun controller material gc.mat isnt a problem, but when I try to verify it in the gun controller script, the material is equal to null. I test this using this code:

Code (CSharp):

1. if(mat != null) Projectile.GetComponent<Renderer>().material = mat;
2. else print ("I am a failure.");
3. Instantiate(Projectile, SpawnPoint.transform.position, Quaternion.Euler(0, 0, 0));

This is a problem because the material of the next Projectile I'll instatiate is not what I want it to be. These are my two questions: What causes Material mat to be null when I call it in my Gun Controller and what can I change to correctly assign my new material?

 

I finally found a solution! The problem was caused by having two different instances of my GunController. As such, the material of the actual GunController is never assigned. All I had to do was to get the GunController-component of the gun itself:

Code (CSharp):

1. gc = transform.GetComponentInParent<GunController>();

In my case I referenced the parent, since I also required the angle of the gun.
