U3D notes (3)

Game body message transmission:

GameObject. SendMessage-send messages to your own scripts

GameObject. BroadcastMessage-send messages to itself and its child

GameObject. SendMessageUpwards-send messages to itself and its parent

PS: GameObject. SendMessageUpwards ("MotherFunction", "Hello ")

You can also use the delegate and event mechanisms in C # To break the structural limitations of the Game objects that transmit messages above.

Dispatcher segment:

Public delegate void EventHandler (GameObject e );

Public event EventHandler MouseOver;

Void OnMouseOver (){

If (MouseOver! = Null ){

MouseOver (this. GameObject );

}

}

Listener segment:

Dispatcher ev = this. GameObject. Find ("Cube"). GetComponent <Dispatcher> ();

Ev. MouseOver + = myFunction;

Void myFunction (GameObject e ){

// E is Dispatcher

}
