how to destroy an object permanently ?

Questions & Answers
1

i have a gate that asks question before you will be able to enter. if you clicked the correct answer, the gate must be destroyed.
My problem is that, after i answered the question correctly, the gate object will be destroyed and my character will pass to the other side but when i move back to where the gate object was, the collision is still there and it would ask me again? do you know how to resolve this? here is my code:

var showGUI = false;

var isopen : boolean;

var launcherUpgrade1 : Texture2D;

function Start ()

{

transform.collider.isTrigger = true;

renderer.enabled = true;

}

function OnTriggerEnter (col : Collider) {

if(col.gameObject.tag == "TIGER" )

{

 transform.collider.isTrigger = false;

    showGUI  = true;

   

}

if(showGUI == false)

{

	transform.collider.isTrigger = false;

	renderer.enabled = false;

	showGUI= false;

}

}

function OnGUI () {

if (showGUI) {

GUI.Box (Rect (10,10,500,200), "Question 1: blah blah blah blah");

if (GUI.Button (Rect (20,40,80,20), "a. 1611")) // thsi is the correct answer

{

	transform.collider.isTrigger = true;

	renderer.enabled = false;

	showGUI=false;

	isopen = false;

		

			

}



 else if(GUI.Button (Rect (20,60,80,20), "b. 1711"))

{

	transform.collider.isTrigger = false;

	isopen =false;

	 

}



 }

}

You need to use Destroy( gameObject ) if you want all the object to be destroyed, or Destroy( collider ) for just the specific component.

You don’t need, by the way, to use transform.collider, you can access collider directly, it’s a Component property.
