Hi,
i want to build a pauseGameScreen, so when the game is running and F12 is pressed, i wan to change the current app state to the pauseScreenState but i only receive this message:
[java]
java.lang.IllegalStateException: Scene graph is not properly updated for rendering.
State was changed after rootNode.updateGeometricState() call.
Make sure you do not modify the scene from another thread!
Problem spatial name: Gui Node

[/java]
to do this i’ll make somethuing like this:
[java]
(update-loop)
if(pause) {
stateManager.detach(this);
stateManager.attach(gamePausedState);
pause = false;
}
(actionlistener - also implemented)
if (binding.equals(“PauseGame”)) { //Trigger is also defined and added to inputmanager
pause = true;
}
(keylistener)
[/java]
so any ideas whats wrong here?
thanks,
tom
Never do anything to the scene graph on stateAttached() and stateDetached() since they may or may not be run from the proper thread. They are always run from the thread that called attach() or detach().
I’m not sure that’s your problem here, though… but it’s worth fixing to see.
Add stuff in initialize() and remove it in cleanup(). The “right” answer is actually to do some enable/disable management of your own but since you are disabling by removing then using initialize() and cleanup() should see if this is some weird threading problem or something else.
There is nothing wrong in the code you posted that I can see so it must be in the code you didn’t post.
What does the pauseScreenState and “this” state do? Are they doing things on the sceneGraph in either stateAttached or stateDetached?
Are you running the latest table updates or the crusty old plain beta?
