When you plan your script, ask yourself, when does the thing you want to happen occur? This is where events come into play. There is a large selection of pre-defined events, including When World is Started, Object Collisions, Enter and Exit events. We can even get events from when a player presses one of their controller’s buttons. For even more control we can create custom events, and cause the event to go off by either sending an event to another object, or on a delay.
