It keeps my code sparated into neat modules. I have a separate draw function which runs after calling update(deltaTime) on the model (sprites). Without timers the code could become a mess with lots of time-keeping variables decremented on each update to the game loop and lots of tests to see which state the sprites are in accordingly... > > On Fri, Dec 2, 2011 at 5:45 AM, John Goche <[email protected]>wrote: > >> >> Hello, >> >> I have an android game which uses timers to update the screen sprites. >> When the user wishes to pause the screen I have to know which timers >> are pending and how long is missing before their expiration time.
