How can i make diamonds fall down? I mean when i dont touch diamons with ball they still fly in the air, but then ball touch them they destroy and this is right. But how can i make them fall down if ball dont touch them?

Here the code:

  • void OnTriggerEnter(Collider col){
  • if (col.gameObject.tag == “Diamond”) {
  • GameObject part = Instantiate (particle, col.gameObject.transform.position,
  • Quaternion.identity) as GameObject;

Add a Rigidbody to an object for it to be affected by gravity and other forces.

Do you have some invisible collision there? You could put the diamonds on their own collision & the collision yoh want to avoid on another, then disable collision between the two.
