Small template for working with mutiple local gamepads in Unity (using new Unity Input System). This template provides simple gamepad manager (for up to 8 devices), assigns each connected device to a new Player and assigns some unique fields (player id, name and color).
- Add new input system to your Unity project via Window > PackageManager (Advanced > Show preview packages) > Input System > Install
- Add DeviceCTRL.cs, InputCTRL.cs, Player.cs and InputMaster.inputactions to your project
- Click on InputMaster.inputactions and generate C# class
- Create empty GameObject and attach DeviceCTRL script to it (this object will be the manager of newly connected gamepads)
Your gamepads should now be properly registered when connected and disconnected. Now you can attach InputCTRL.cs to the instantiated player GameObject for your game, set its gamepadIndex and trigger its InitInputCTRL() to initialize input for that player.
How do I know the proper gamepadIndex? Use DeviceCTRL.cs's List<LocaL.Player> players and player's gamepad.deviceId field.
You can now use InputCTRL.cs's input field to read player's input.
For additional actions to do after new gamepad/Player is added, modify HandleNewPlayer(LocaL.Player player, bool alreadyConnected) at the end of DeviceCTRL.cs. To add more input actions, follow instructions in comments above struct PlayerInput in Player.cs.
This is a freshly made template after learning a bit about the new input system, it still hasn't been thoroughly tested (especially with more devices), so feel free to PR bug fixes or changes.
