This might be covered later in the course, but I figured out a (probably not best) way to make the enemies flash white when hit!
I basically used a coroutine that changes the material. I don’t know how to make it fade rather than be a binary flash.
Material baseMat;
Material hitMat;
IEnumerator FlashHit()
{
ChangeMat(hitMat);
yield return new WaitForSeconds(0.05f);
ChangeMat(baseMat);
}
