public void	init() Overrides java.applet.Applet.init. initialise applet by adding a canvas to it, this canvas will start the LWJGL Display and game loop in another thread.
public void	start() Overrides java.applet.Applet.start. Called by the browser or applet viewer to inform this applet that it should start its execution.
public void	startLWJGL() Once the Canvas is created its add notify method will call this method to start the LWJGL Display and game loop in another thread.
public void	stop() Overrides java.applet.Applet.stop. Called by the browser or applet viewer to inform this applet that it should stop its execution.
private void	stopLWJGL() Tell game loop to stop running, after which the LWJGL Display will be destoryed.

public void destroy()

Overrides java.applet.Applet.destroy.

Applet Destroy method will remove the canvas, before canvas is destroyed it will notify stopLWJGL() to stop main game loop and to destroy the Display

init	back to summary

public void init()

Overrides java.applet.Applet.init.

initialise applet by adding a canvas to it, this canvas will start the LWJGL Display and game loop in another thread. It will also stop the game loop and destroy the display on canvas removal when applet is destroyed.

start back to summary

start	back to summary
public void start() Overrides java.applet.Applet.start. Doc from java.applet.Applet.start. Called by the browser or applet viewer to inform this applet that it should start its execution. It is called after the `init` method and each time the applet is revisited in a Web page. A subclass of `Applet` should override this method if it has any operation that it wants to perform each time the Web page containing it is visited. For example, an applet with animation might want to use the `start` method to resume animation, and the `stop` method to suspend the animation. Note some methods, such as `getLocationOnScreen`, can only provide meaningful results if the applet is showing. Because `isShowing` returns `false` when the applet's `start` is first called, methods requiring `isShowing` to return `true` should be called from a `ComponentListener`. The implementation of this method provided by the `Applet` class does nothing.

public void start()

Overrides java.applet.Applet.start.

Doc from java.applet.Applet.start.

Called by the browser or applet viewer to inform this applet that it should start its execution. It is called after the init method and each time the applet is revisited in a Web page.

public void startLWJGL() Once the Canvas is created its add notify method will call this method to start the LWJGL Display and game loop in another thread.

stop back to summary

stop	back to summary
public void stop() Overrides java.applet.Applet.stop. Doc from java.applet.Applet.stop. Called by the browser or applet viewer to inform this applet that it should stop its execution. It is called when the Web page that contains this applet has been replaced by another page, and also just before the applet is to be destroyed. A subclass of `Applet` should override this method if it has any operation that it wants to perform each time the Web page containing it is no longer visible. For example, an applet with animation might want to use the `start` method to resume animation, and the `stop` method to suspend the animation. The implementation of this method provided by the `Applet` class does nothing.

public void stop()
