Destroy On Touch

What is your question? Are you wanting to know how to adapt that code so that it destroys a Killable and activates the World Variable Modifiers for it?

Ok. Replace your Destroy line with this.

var kill = gameObject.GetComponent<Killable>();
kill.DestroyKillable ();

This is C#. I don't know UnityScript. Hopefully you can convert it without much trouble.

Excellent! Is there another question here?

Which type of spawners? Triggered or Syncro?

In Scene 2.TriggeredSpawners, the first problem is that the enemies are in IgnoreRaycast layer, which cannot be hit by raycasts. Make a new layer "enemies" and make all the enemy prefabs use that layer.

Next, if you put this script on the enemy prefab, it will kill ALL of them when you hit one of them. That's not what you want. Instead, put this script onto the Player prefab. This fixed script works for me:

using UnityEngine;
using System.Collections;

public class ClickToKill : MonoBehaviour {
void Update() {
var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
if (Input.GetMouseButtonDown(0)) {

RaycastHit hit;
if (Physics.Raycast(ray, out hit, Mathf.Infinity)) {
if(hit.collider == null) {
return;
}

var kill = hit.collider.GetComponent<Killable>();
if (kill != null) {
kill.DestroyKillable();
}
}
}
}
}

I will include this script in the next version. And this should let you use spawners.

No problem! Actually the updated Core GameKit with this script is already live. I also added an option to inflict X damage on the Killable instead of Destroying it.
