I'm making a game which has a points system which is altered whenever the player picks up the coins. I have designed particle effects for the coins which i've turned into prefabs but the particles start when the game loads. this isn't what i need. Code: #pragma strict var coinparticles : Transform; function OnTriggerEnter (info : Collider) { if (info.tag == "gPlayer") { Debug.Log("Add coin counter here!"); var effect = Instantiate(coinparticles, transform.position, transform.rotation); Destroy(effect.gameObject, 3); Destroy(gameObject); } } "gPlayer" is one of the tags i'm using for characters. "coinParticles" is the name of the particle system. :help:
