Returns 0 if the timer is inactive. Returns [code]true[/code] if the timer is paused. Returns [code]true[/code] if the timer is stopped. Pauses the timer. If [code]paused[/code] is [code]true[/code], the timer will not process until it is started or unpaused again, even if [method start] is called. Starts the timer. This also resets the remaining time to [code]wait_time[/code]. Note: this method will not resume a paused timer. See [method set_paused]. Stop (cancel) the Timer. If [code]true[/code], Timer will automatically start when entering the scene tree. Default value: [code]false[/code]. If [code]true[/code], Timer will stop when reaching 0. If [code]false[/code], it will restart. Default value: [code]false[/code]. Processing mode. Uses TIMER_PROCESS_* constants as value. Wait time in seconds. Emitted when the Timer reaches 0.
