Detecting Collisions

Unity Engine
1

Can someone show me how to detect collisions in Javascript? like, “if this touches this than do this” kind of thing.

If you’re using a collider:

function OnCollisionEnter(collision : Collision)
{
    if(collision.gameObject.name == "ThatOneObject")  // Or collision.gameObject.tag
    {
        // Do something
    }
}

There is also:
OnCollisionExit and OnCollisionStay

If you’re using isTrigger:

function OnTriggerEnter(collider: Collider)
{
    if(collider.gameObject.name == "ThatOneObject")  // Or collider.gameObject.tag
    {
        // Do something
    }
}

There is also OnTriggerExit and OnTriggerStay.
