    In Javascript, how do I change the transform of an object from a script attached to a different object?

    Here's an example: I have scene with two objects: a b all and a box. I want a script attached to the ball to code so that when the user clicks on the ball, the box tanslates.

    I don't need the translation code, just a line showing how to reference the box object from within the script attached to the ball object.

    Thanks!

    The easiest way is to just create a variable target which you assign in the inspector.

    Code (csharp):
    1.  
    2. var target : Transform;
    3. function Update ()
    4. {
    5.   target.position.x += 1;
    6. }
    7.  
    target appears in the inspector and you can assign it to any transform.
    Note that this script will give you an exception if you don't assign a target.

    Another way is using tags:
    Code (csharp):
    1.  
    2. function Update ()
    3. {
    4.   target = GameObject.FindGameObjectWithTag ("Box").transform;
    5.   target.position.x += 1;
    6. }
    7.  
    Then have to create a tag "Box" and tag the box with the "Box" tag.
