Subscribe to Action (SteamVR 2.x)

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

Poll Action (SteamVR 2.x)

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);
}
