Shift lock Script does not work properly

[r266s (r266)]

for some reason the script wont run after creating ContextActionService with the TouchButton as true.

normal play test:

client and server play test

Code that wont run

ContextActionService:BindAction(ACTION_NAME, OnShiftLock, true)

local ActionButton: ImageButton = ContextActionService:GetButton(ACTION_NAME)

print(ActionButton)

repeat 
	task.wait()
	ActionButton = ContextActionService:GetButton(ACTION_NAME)
	print("ssss")
until ActionButton ~= nil

print(ActionButton)

ActionButton.AnchorPoint = Vector2.new(0.5, 0.5)
ActionButton.Position = UDim2.fromScale(0.94, 0.89)
ActionButton.Size = UDim2.fromScale(0.12, 0.17)
ActionButton.Image = disabled_Image_ID

while task.wait() do
	if ActionButton then
		print("sss")
		ActionButton.Image = if ACTIVED then enabled_Image_ID else disabled_Image_ID
	end
end

What’s happening is the GetButton line infinitely yields because the ContextActionService Gui isn’t parented to PlayerGui quick enough which is odd to say the least. In order to fix this you need to wait for the ContextActionService Gui to be parented to the PlayerGui.

Here’s the code to fix it, you can put this under the bind action line:

local PlayerGui = LocalPlayer:WaitForChild("PlayerGui")
local ContextActionServiceGui = PlayerGui:WaitForChild("ContextActionGui")

This worked but i decided to remove the ContextActionService and use the GUI instead but thank you
