Determine which controller is sending me Actions in SteamVR

Question

I'm starting to use the SteamVR action-driven Input system Version: 2.3.2 (sdk 1.4.18). I attached a laser pointer script similar to the Steam version to each controller. Now, when I squeeze the trigger, BOTH scripts receive the squeeze action. Well, of course they do. So how can I determine if the squeeze is from MY controller to ensure that I only respond to that?

I already looked at the SteamVR_Input_Sources parameter. It always reads 'any', so that doesn't help.

Maybe there is an option somewhere to filter which controller messages you wish to receive or a way to determine who invoked the action...?

You should be able to see it in the unity editor. Give me a sec. I'll get you a better description — chillinOutMaxin, Aug 18 '19 at 14:51

You can either subscribe to the action like

public void SubscribeToPlayerAction(SteamVR_Action_Boolean action, SteamVR_Action_Boolean.ChangeHandler onAction)
{
    action.AddOnChangeListener(onAction, SteamInputSource); //SteamInputSource can be Left Right or Any
}

Or you can poll

public bool CheckForPlayerAction(SteamVR_Action_Boolean action, ButtonAction buttonState = ButtonAction.PressDown)
{
    if (buttonState == ButtonAction.PressDown) return action.GetStateDown(SteamInputSource);
    if(buttonState == ButtonAction.IsPressed) return action.GetState(SteamInputSource);

    return action.GetStateUp(SteamInputSource);
}

Thanks @Anders! I'll go with polling then. I think the new action-driven Input System is not for me (yet?). — Bob Sir Viver, Aug 18 '19 at 16:26

If you go to windows and open the SteamVR input live view, you can get this menu

This menu will show you which controller is receiving an action
