void OnDisble ()

RocksTrigger.onTrigger -= OnTrigger;
}
void OnTrigger ()
{
EnabledRigidbody();
}
We used the
OnEnable()
function to add a function that will be called when the event
is triggered. We use the
OnDisable()
function to remove a function when the game
object is inactive. Then, the
OnTrigger()
function is the function that will be called
when the event is triggered, which we call the
EnabledRigidbody()
function, to
make the rock slide.
Tip
The
delegate
and
event
methods are better than the
BroadcastMessage
method
that we've used in
Project 5
,
Build a Rocket Launcher!
, because we don't have to set up
the listener as a child of the event trigger. Also, the
BroadcastMessage
method is
slower than the
delegate
and
event
methods because it needs to iterate to all the chil-
dren in this game object to be able to call the function.
