Changing array materials on collision (c#)

Archived Forums Questions & Answers

Hi all, I am having a bit of trouble getting individual objects in an array to change their material on collision. The problem I am having is that this happens across the array and not just to specific blocks. The first collision works correctly, but if i then collide with an un-hit block, its material skips to the secondHit material or thirdHit material (if 2 different blocks have been hit previously).

As you can see i am also changing mass on collision, this seems to be working fine, which just adds to my confusion.

How can i get the individual blocks in the array to hold their own hit value? I thought using a foreach loop would fix this.

any help would be brilliant, thanks in advance!
A.

public Material firstHit;

public Material secondHit;

public Material thirdHit;

public static int hitNumber = 0;

void OnCollisionEnter (Collision collision)

{
	foreach (GameObject block in BlockCount.blocks) {

               if (collision.gameObject == block) {

			block.rigidbody.mass = block.rigidbody.mass / 2;

			hitNumber++;

			print(hitNumber);

			if (hitNumber == 1) {

				block.renderer.material = firstHit;

			}

			if (hitNumber == 2) {

				block.renderer.material = secondHit;

			}

			if (hitNumber == 3) {

				block.renderer.material = thirdHit;

				hitNumber = 0;
			}
		}

	}

}

You should make one block with this script that works, then make it a Prefab, then use that Prefab for all the rest of the blocks. Then they’ll all have their own copy of the script with their own hit counts etc.
