How to recreate the PlayerInput class ?

Doc says PlayerInput is built on top of the new input system and can be rewrited.
So, for some reason Im trying my best to recreate it, without success.
What I did so far is a monoBehaviour class with one "InputActionAsset" instance, and one "InputUser" instance.
Then I associate the InputUser instance with the InputActionAsset instance with the "AssociateActionWithUser()" methode, then activate one sheme.
I can't go further ; I have an error when starting:
"InvalidOperationException: Invalid user"

Im trying this because the PlayerInput class does not give me the control I expect for a local multiplayer game.
(I can't navigate through it with original actions/map names like with the class generated by the InputActionAsset)

Now I will use string parameter to use the PlayerInput actions/map because it seems to hard to rewrite, but Im still curious to see if it is possible.

 

InputUser

is a struct that acts like a handle. To create a user, either call

InputUser.CreateUserWithoutPairedDevices()

or use

InputUser.PerformPairingWithDevice()

.

Code (CSharp):

1. // Create a new InputUser that "owns" the keyboard and the mouse.
2. var user = InputUser.PerformPairingWithDevice(Keyboard.current);
3. InputUser.PerformPairingWithDevice(Mouse.current, user: user);
4.  
5. // Give the user a set of actions and choose a control scheme.
6. // (assuming a C# class generated with "Generate C# Class" here)
7. var actions = new MyGeneratedActions();
8. user.AssociateActionWithUser(actions);
9. user.ActivateControlScheme(actions.GamepadScheme);

 

thanks,
I found that I can override actions asset instance directly on PlayerInput, so now I can activate or deactivate actions by their name easily.
