Exception trying to remove default event mappings

Troubleshooting SDK
1

Hello.

I have a SimpleApplication, with the default blue cube. When I add this code to the simpleInitApp() method, it throws an exception:

// Remove default mappings

inputManager.deleteMapping(INPUT_MAPPING_CAMERA_POS);

inputManager.deleteMapping(INPUT_MAPPING_MEMORY);

This is the exception:ago 23, 2013 1:01:24 PM com.jme3.app.Application handleError SEVERE: Uncaught exception thrown in Thread[LWJGL Renderer Thread,5,main] java.lang.IllegalArgumentException: Cannot find mapping: SIMPLEAPP_CameraPos at com.jme3.input.InputManager.deleteMapping(InputManager.java:607) at mygame.UserInput.simpleInitApp(UserInput.java:65) at com.jme3.app.SimpleApplication.initialize(SimpleApplication.java:225) at com.jme3.system.lwjgl.LwjglAbstractDisplay.initInThread(LwjglAbstractDisplay.java:130) at com.jme3.system.lwjgl.LwjglAbstractDisplay.run(LwjglAbstractDisplay.java:207) at java.lang.Thread.run(Thread.java:722)

This is the full code of my simple application:

Thats because the DebugAppState initialize () method has not been called yet, which adds these mappings. It would be better to not add the DebugAppState at all (its added by default with an empty super () constructor)

i.e:
[java]UserInput () {
super (new FlyCamAppState (), new StatsAppState ()); // Only add fly cam and stats
}[/java]

Perfect. Thank you!

inputManager.addMapping(MAPPING_COLOR, TRIGGER_COLOR, TRIGGER_COLOR2);
inputManager.addMapping(MAPPING_ROTATE, TRIGGER_ROTATE);
