I have implemented the functionality of detecting PlayStation versus Xbox controllers. And, it’s working, to an extent.
Issue 1:
Directional inputs have the same return value. This means, if a player presses a d-pad input, then the code knows it’s a gamepad, but it doesn’t know what type of gamepad. (PlayStation or Xbox? the code is not sure.)
Issue 2:
Can’t have more than one controller plugged in at a time.
Steps:
- Play with PS4 remote, move around.
- The UI updates to show PS4-specific prompts
- With PS4 remote still plugged in or connected via Bluetooth, connect an Xbox remote and move around with that.
- The UI updates to show Xbox-specific prompts
- With both remotes connected, switch back to the PS4 remote and move around.
- You can play the game, but the UI does not update to show PS4-specific prompts. Rather, it thinks the PS4 remote is an Xbox remote as Roblox seems to be relying on the last controller that was connected. (Not the last one to have input.)
This could be an issue with my code, which is below, but I’m not sure.
Anyhow, this means that players, if they want the correct UI prompts to show up, they need to unplug their controller and plug it back in. Or, just only have one remote plugged in at a time.

Here’s a link to my game: PB & Jay | In-dev - Roblox
I remember the idea getting shot down a few years back since only Xbox controllers (which don’t have a gyroscope) were officially supported - but with the PlayStation launch I’m hoping the team can revisit.
