Objective complete - mini debriefing
We just created the RocksTrigger and Rocks scripts, which are used to trigger the
rockslide event when the player hits the trigger area. First, we created the Rocks
script and used OnTriggerEnter() to check whether the player has entered the trigger
area or not. Then, we call the onTrigger() event function to send the event to the
listener, which is RocksTrigger , using the delegate and event functions in C#.
However, there are no delegate and event functions in Unity JavaScript. So, we have
to use our custom script, which is the JSDelegate script available in the Chapter7/
Scripts/Javascript folder in the Project view, which already comes with the pro-
ject's package.
Next, we listen to the trigger by adding the following script:
// Unity JavaScript user:
function OnEnable () : void
{
RocksTrigger.onTrigger.Add(OnTrigger);
}
function OnDisble () : void
{
RocksTrigger.onTrigger.Remove(OnTrigger);
}
function OnTrigger () : void
{
EnabledRigidbody();
}
// C# user:
void OnEnable ()
{
RocksTrigger.onTrigger += OnTrigger;
