Activate script when player enters trigger zone.

[cryman]

Hello!
I have the following script:
private var Movements = new Array();
private var MovementIndex : int = 0;
private var rewinding : boolean;

function Update ()
{
    if(!rewinding)
    {
       Movements.Add(transform.position);
       MovementIndex++;
    }
 
    if(MovementIndex > Movements.Count - 1)
    {
       MovementIndex = Movements.Count;
    }
 
    if(Input.GetKey(KeyCode.Tab))
    {
       rewinding = true;
       Rewind();
    }else
    {
       rewinding = false;
    }
}
 
function Rewind ()
{
    MovementIndex--;
    transform.position = Movements[MovementIndex];
    Movements.RemoveAt(MovementIndex);
}

I’m prety new to unity and im trying to figure out how to make this script attached to objects in the trigger zone only work when the player enters the trigger zone…any ideas? Thank you.

do you mean something like this?

//attach this script to your trigger

var Player : GameObject;
var Script : theScript;

function OnTriggerEnter(other : Collider) //Check if something has entered the trigger ( and declares this object in "other" )
{
   if(other.collider.tag == Player.tag) //Checks if the Player is inside the trigger
   {
      Script = GetComponent(theScript); 
      Script.enabled = true; //enables theScript.
   }
}

You have to change
“theScript” to the name of the script you want to enable.
e. g. when you named your script “Toaster” it would be

var Scipt : Toaster;

Script = GetComponent(Toaster);

you can disable the script again if you copy-paste the script and change

function OnTriggerEnter(other : Collider)

to

function OnTriggerExit(other : Collider)

and

Script.enabled = true; //enables theScript.

to

Script.enabled =false; //this time it will disable the script

I hope i could help you

Or you can add a bool and say at the begining of the scripts:
if (example == true)
{
// your script
}

then you tag your collider and say OnTriggerEnter(Collider other) bla bla if (other.tag == namethething) example == true that’s it.

P.S: this is in C#…
