This is my code:

void OnTriggerEnter(Collider collide) {
  if (collide.gameObject.transform.tag == "Laser") {
    Debug.Log ("Inside If");
    Transform resourceTransform = collide.transform;
    Transform[] tf = new Transform[resourceTransform.childCount];
    for(int i = 0; i<= resourceTransform.childCount-1; i++){
      tf[i] = resourceTransform.GetChild(i);

    Debug.Log ("Child Count Before: " + resourceTransform.childCount);

    Debug.Log ("Child Count After: " + resourceTransform.childCount);
    Vector3 centerOfMass = resourceRb.centerOfMass;
    Explode (tf, centerOfMass);

Everything is working fine, except the childCount property is always zero and that screws everything else up. Here's an image of the hierarchy:


The script is on cube1 and the object has 12 or so children. So why is childCount equal to zero? Is it a problem with Unity itself?

  • \$\begingroup\$ You seem to be getting the child count of the laser. \$\endgroup\$ – Ben Jul 19 '15 at 13:56

collide.Transform refers to the object you are colliding with. Change this line

Transform resourceTransform = collide.transform


Transform resourceTransform = transform

and try again
