Functions

timer.delay()

timer.delay(delay,repeat,callback)

Adds a timer and returns a unique handle You may create more timers from inside a timer callback. Using a delay of 0 will result in a timer that triggers at the next frame just before script update functions. If you want a timer that triggers on each frame, set delay to 0.0f and repeat to true. Timers created within a script will automatically die when the script is deleted.
