Hi

func _input(event):
	if event.is_action_released("forward"):
		if (not $AccTimer.get_time_left() == 0):
			print('$AccTimer')
		else:
			print('hi')
			$AccTimer.start()

this code doesn't work properly
First it enters in second logic and print "hi" Then
no matter how many time elapse Its
always enters in first logic and print '$AccTimer'
I set Timer to "1" to "0.3" ...

    Serhy if (not $AccTimer.get_time_left() == 0):

    Since time_left is a float, that should be:
    if $AccTimer.time_left > 0.0:

    Equality tests (==, !=) on floats are usually not reliable.

        Serhy
        Don't forget 2 important lines:

        $AccTimer.one_shot = true
add_child($AccTimer)

        then start your timer$AccTimer.start()

        EDIT:
        oh, timer is already in node tree, so just add this line before you start timer:
        $AccTimer.one_shot = true

            DaveTheCoder the same thing

            func _input(event):
	if event.is_action_released("forward"):
		if ($AccTimer.time_left > 0.0):
			print($AccTimer.time_left )
		else:
			print('hi')
			$AccTimer.start()

            its like after Timer starts It
            never goes zero
            'Null
            Null
            hi
            Null
            Null
            Null
            Null
            0.116667
            Null
            Null
            0.283333
            Null
            Null
            Null
            0.283333
            Null
            Null
            '
            autorestarting?

              AspireMint just swa it So I checked
              in the script I got error "$' unaxpected syntsx ... something I dont remember
              and 'add_child($AccTimer) ' either
              i found 'One shot' check box in the inspector and just enabled it
              works Thanks

                  Yes, sorry, my bad. I edited it. I was testing it with Timer.new() thats why I had to manually append it to node tree. But you already have instance of timer in node tree, so no need to add_child.
