Actions bound to ButtonL2 are triggered by clicking on the main menu button

[SamSwifthoof]

If you bind an action to Enum.KeyCode.ButtonL2 it will be triggered on PC if you click on the “Roblox menu” button in the top left corner of the screen.

Steps to reproduce:

1. Add a script to StarterPlayerScripts with the following content:

    local ContextActionService 	= game:GetService("ContextActionService")
   
    ContextActionService:BindActionAtPriority(
    	"L2Test", 
    	function(actionName, inputState, inputObject)
    		print("L2 triggered")
    		return Enum.ContextActionResult.Sink		
    	end, 
    	false, 
    	Enum.ContextActionPriority.High.Value,
    	Enum.KeyCode.ButtonL2
    )
   

2. Run the game and open the “Roblox main menu” by clicking on the button the top left corner

Expected results: “L2 triggered” should not be printed to the console

Actual results: “L2 triggered” is printed 4 times to the console

I have only tested this in Studio in multiple projects, not on Roblox.com.

Also did some further testing where I disconnected my Xbox controller and restarted studio, the same issue still occurs.

See:

Binding Enum.KeyCode.R with ContextActionService, will also fire when clicking the Roblox menu

This is expected behaviour, you need to check the input state passed to the function. When the R button is bound over by the in game menu, your function is fired with the Cancel UserInputState. This is so you can reset any state that needs to be reset when your bound action is superseded by another action. You can fix this by only running the function on Enum.UserInputState.Begin local ContextActionService = game:GetService("ContextActionService") local function pressedR(actionName, inputStat…

I did miss the fact that it sent a “Cancel”.

This makes perfect sense, thank you.
