![]() ![]() This is because time is subtracted in chunks, equivalent to the duration of the last frame. This is because the remaining time will almost always be a negative number when the timer stops. You may also notice that, when the timer ends, I’ve manually set timeRemaining to zero. Remember to lock the timer to zero when it ends It also means that the final action, which is triggered when the timer reaches zero, only fires once.
