Can't proceed next level when the object destroy not complete.

simply add Application.loadedLevel ("levelName");

Before the Destroy action not After it

Add a function OnDestroy( ) to each one of your 4 objects. In this function, you'll simply turn a boolean variable to TRUE. When all the four variables are TRUE, you can access next level. What I mean is something like this:

(NOTE: the following code is untested, and its purpose is just to give you a general idea on this)

This is a global variable, and it'll contains all the flags for checking the destructions:

var flags : boolean[] = new boolean[4];

---

This script is attached to each one of the 4 objects (with different "object_index"!!!), and this will be activated if the object is destroied:

var object_index = 1; //object_index's value is 1 for the 1° object, 2 for the 2° one,...,4 for the 4° one
function OnDestroy(){
   flags[object_index] = 1;
}

---

This function has to be called from the Update() of the object in which you check for the level changing:

function Update(){ //... Check_next_level; //... }

function Check_next_level(){ going_to_next_level = 1; for (var i=1; i++; i<5){ if (flags[i] == 0){ going_to_next_level = 0; break; } } if (going_to_next_level){ level_index++; //You have to declare this outside, and use it to mantain the reference to the actual level Application.LoadLevel(level_index); } }
