How to make my game objects spawn when i walk through collider

Hi Guys. I’m Creating a Zombie game. (Not Relevent) How do i make them appear only when i walk through the second rooms collider. Is there a script reference or tutorial on how to do this?

eg. Kill all enemys in first room. When i walk through the collider more enemys will spawn. Can i hide enemys by deactivating childeren and how would i reactivate on colider enter. Any info is appreciated thanks.

All you need to do is use the OnCollisionEnter function and implement your Instantiate(SomePrefab) function where SomePrefab is a public variable defined on the class (C#) or just outside of functions (UnityScript) which you assign the target game object to within the editor.

you can use this script on all your spawn colliders and every time assign a completely different game object if you want

mate. Thank you! Appreciate it. Question solved.

var items : GameObject ;

function OnTriggerEnter()
{
    collider.enabled = false;
 
    var index : int = Random.Range(1,items.length);
    var thePrefab : GameObject = items[index];
 
    var instance : GameObject = Instantiate(thePrefab, transform.position, transform.rotation);
 
}
