I have a thread that does all my rendering code for a game (including animations). I want to be able to communicate with that thread via Messages instead of locking / synchronization. This means that I need to both support a message queue and *also* support my own rendering loop. Normally I would just clear the message queue every frame of rendering so worst case scenario the messages sit on the queue for one frame before getting cleared out. This also gives a bit of priority to messages in that if the queue backs up the rendering will take a back seat until it empties out.
Everything was going fine until I realized that Looper doesn't have a "Clear the Queue" function! I looked at the source code for Looper.loop() and it appears that the code necessary to manually traverse the MessageQueue is protected, so I can't even write the ClearQueue function myself. Does anyone here have any feedback on how I can have a thread that keeps the MessageQueue clear at the same time as allowing me to peg the CPU rendering as many frames per second as I can? My current thought is to insert a message into the MessageQueue along the lines of "RenderOneFrame". When this message is popped off the queue I would render one game frame. Before returning from my rendering code though I would push another copy of the RenderOneFrame message back onto the queue. This means any messages added to the queue while I was busy rendering the frame would get processed before the RenderOneFrame mesage and once the queue was "clear" (ie: RenderOneFrame message was back on top) I would repeat the process. I suspect that this will work, though I am open to suggestions for either a clear or faster method (I'm more interested in clean at this point, but at optimization time I'll be interested in faster if I bottleneck on this code). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
