Changing world and all objects

[Mr_Chaos]

Hi.

I have an android app using JPCT-AE where the user can select different worlds, when a world is selected I want to show a progressdialog while the data is loading (data is loading asynchroniously using background tasks).
My problem is that sometimes when I change "world" I get exception, that I can see are because jpct-ae is not multi threaded, but how do I fix this.
I have a volatile variable in my renderer, that only allows rendering once the data is loaded, but for some reason i still get crashed in JPCT.
Do I have to pause the GLSurfaceView while loading or ? any ideas on how to do this

You have to stop all jPCT related things (i.e. rendering and processing) while loading. Anything else will cause troubles.

How do I do that ?
Currently I'm making sure I don't render anything, but is that enough or do I have to do something else when I'm adding new objects ?

glsurfaceview has a rendermode: WHEN_DIRTY. use this mode and request render every frame.
or put all operations in OnDrawFrame() method.

If it crashes when adding new objects, you are rendering something. Can you simply synchronize both code blocks on the same object?
