About customEventExample

This example demonstrates a simple game. A GameEvent class is used to store the bullet and bug that just collided.

After studying this example, you'll understand how to create an object to generate custom events using a class based on ofEventArgs

In the code, pay attention to:

OF classes and functions to create custom events:
ofEventArgs, base class for events that don't send any arguments like draw or update
ofAddListener to add a listener method to GameEvent
ofNotifyEvent() to notify the GameEvent

When launching this app, you should see a screen with

nine small randomly positioned black circles. Bugs crawl out of the circles and move around the stage.
a canon pointing upwards at the bottom center of the window rotating on it's bottom vertical axis, its angle mapped to the horizontal mouse position.
when pressing on the spacebar, the canon shoots a pink bullet. If a bullet hits a bug, the bug disappears.
a text overlay at the top left corner displays the number of bullets shot and bugs killed.
A message in the console: "Game Event: BUG HIT" when bullet and bug collide.

Instructions for use:

Move the mouse on it's horizontal axis to aim canon. Press spacebar to shoot bullets at bugs.
