ContextActionService not passing "Cancel"

Help and Feedback Scripting Support
#1

I’ve run into some unexpected behavior with ContextActionService:UnbindAction() that may possibly be a bug, but could also be me misunderstanding something, as this is my first time using ContextActionService.

Intended behavior when run from a local Script::

  • By holding Left Shift, “Run” should be printed.

  • Holding Left Control while still holding Shift should print “UnRun”, as the Run action has been unbound and “Cancel” has presumably been passed.

  • “Crouch” should be printed.

local CAS =game:GetService("ContextActionService")

local function HandleAction(ActionName,InputState,InputObject)
	print(ActionName,InputState)
	
	
	if ActionName =='Run' then
		if InputState ==Enum.UserInputState.Begin then
			print('Run')

		elseif InputState ==Enum.UserInputState.End or InputState ==Enum.UserInputState.Cancel then
			print('UnRun')
		end
		
		
	elseif ActionName =='Crouch' then
		if InputState ==Enum.UserInputState.Begin then
			print('Crouch')
			CAS:UnbindAction('Run')
			
		elseif InputState ==Enum.UserInputState.End or InputState ==Enum.UserInputState.Cancel then
			print('UnCrouch')
			CAS:BindAction('Run',HandleAction,false,Enum.KeyCode.LeftShift)
		end
	end
	
	
end

CAS:BindAction('Run',HandleAction,false,Enum.KeyCode.LeftShift)
CAS:BindAction('Crouch',HandleAction,false,Enum.KeyCode.LeftControl)

Actual behavior

(“Cancel is sent if some input was in-progress and another action bound over the in-progress input, or if the in-progress bound action was unbound.”)

  • Releasing Shift while still holding Control prints “Crouch” again, which seems very odd and unintentional.

I’ve looked around a bit and can’t find any similar problems reported which leads me to believe I may be understanding or implementing something wrong?
