Gamepad behaves unexpectedly when connecting a function to UserInputService (InputBegan, InputEnded, InputChanged)

Help and Feedback Art Design Support
#1

I have connected a function to three UserInputService events (InputBegan, InputEnded, and InputChanged), in a such manner:

UIS.InputBegan:Connect(function(inp, gp) IM.InputBegan(inp, gp) // I do some calculations here end)

The issue is that when this part of the code is present, gamepad/xbox controls seems to behave in an undefined manner, as the jump button sometimes works and sometimes doesn’t, and the thumbstick works in a laggy-like fashion.

I was wondering why this happens and what possibilities exist to solve it?
Thanks a lot

The ButtonA problem might be related to this:
https://devforum.roblox.com/t/contextactionservice-doesnt-fire-consistently-for-playeractions-characterjump-when-buttona-is-used/179224

So that part of the problem might be a bug with user input in the engine. EDIT: I think the gameProcessedEvent parameter might not be correct for ButtonA actions, try ignoring it for ButtonA and see what happens.

I’m not sure about the “thumbstick working in a laggy-like fashion”, any chance you can add a gif/code showing this?

#3

Just checked it out, although I’m using UserInputService instead of ContextActionService, that might have something to do with this issue, time to wait for a solution/fix then :slightly_smiling_face:

Also this is me moving the thumbstick in the upwards direction (holding the direction at least during intervals of 1 second)

Is this similar to your code?

--on input began
if gpe then return end
--if thumbstick
resetmovement()

--on input changed
if gpe then return end
--if thumbstick
setmovement(input)

--on input ended
--if thumbstick
resetmovement()

--no modification to movement in later code

Also how are you moving the character?

#6

My code does contain if gpe then return end but it doesn’t mess with character movement at all. The character should only move due to roblox core code.

#7

Have you checked to make sure it does not yield and that it runs fairly quickly?

It should run failry quickly, but I even put all the function’s code in a coroutine and it still bugs out
