Functions

timer.cancel(handle)

You may cancel a timer from inside a timer callback. Cancelling a timer that is already executed or cancelled is safe.

PARAMETERS

handle

the timer handle returned by timer.delay()

RETURNS

true

if the timer was active, false if the timer is already cancelled / complete

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.

PARAMETERS

delay

time interval in seconds

repeat

true = repeat timer until cancel, false = one-shot timer

callback

function(self, handle, time_elapsed) timer callback function

self: object The current object
handle: number The handle of the timer
time_elapsed: number The elapsed time - on first trigger it is time since timer.delay call, otherwise time since last trigger

RETURNS

handle

identifier for the create timer, returns timer.INVALID_TIMER_HANDLE if the timer can not be created

Indicates an invalid timer handle
