getTimer function
Returns the elapsed time since the start of the GraphX scene in milliseconds, or 0 if it hasn't been started yet.
This function is equivalent to the getTimer()
function in ActionScript or
JS. If the stopwatch is not running, it starts it automatically.
Implementation
int getTimer() {
if (!_stopwatch.isRunning) {
_stopwatch.start();
}
return _stopwatch.elapsedMilliseconds;
}
