Hi,
I had a lot of difficulties getting the threading and app lifecycle
issues done, too. For my part, this was much more confusing than
getting the actual game done. ;)
The good thing is: you do not have to do too much for the render- and
logic-thread separation because most of the rendering time is getting
spent "outside" of your renderer's onDraw method. This is how I got
this done: The "Game" itself is owned by the glSurfaceView renderer
instance. the when the game starts (at onResume), I start an
updatethread that is very simple an does something like
while(bKeeprunning) {
synchronized(Game.sInstance) {
Game.sInstance.update();
}
Thread.sleep(50);
}
I have to add that my game logic is doing only this: logic. The world
gets simulated. This is done less than 10 times per second - this is
why I can have it sleep for 50 ms. sleeping is important here to give
the render thread time to do this (I don't remember the full method
signature, but I think you know what I mean):
onDrawGlFrame() {
synchronized(Game.sInstance) {
Game.sInstance.render();
}
Thread.sleep(5);
}
I defined the updatethread as class inside of the Renderer because it
is so small. This gave me a huge performance boost. Handling the app
lifecycle is less easy (at least for me).
