    3. Game #2, Rocket Commander > Time for action — modifying the launcher class

    Time for action — modifying the launcher class

    To modify the launcher class, follow the ensuing steps:

    1. Open the launcherClass.monkey file.
    2. Modify the Update method and add a CreateRocket call there. The parameters are the mouse coordinates and the X position of the launcher.
      Method Update:Int()
If KeyHit(triggerKey) And cRockets > 0 Then
CreateRocket(MouseX(), MouseY(), Self.x )
cRockets -= 1

    What just happened?

    We have just activated the functionality that will create a rocket when you hit a trigger key.

    Updating the rockets

    As the game progresses, each rocket should move closer to its target position and check if it has been reached. We can do that with the UpdateRockets function.
