R Button UFPS

I tried everything but I cant seem to get the r button to attack in UFPS, I can get the r button to do everything else like zoom but I cant seem to get it to attack...can anyone help? I tried the axis r but I didn't know what pressing and default meant and didn't know how to set it up

 

I have the same problem

 

You need to add the key assignment for the PS Vita in the script of UFPS where attack function is used and change it to KeyCode.JoystickButton5

eg
if (Input.GetKey(KeyCode.Joystick1Button5)) {
// 'R' is pressed.
// Do Something
}

or like this you can then assign input using input manager
eg
if (Input.GetButton("Attack")) {
// key assigned to 'Attck' action is pressed.
// 'Attck' is assigned in the Input Manager as JoyStickButton 5 which is joystick button 5, 3rd axis
}

I use RealsiticFPS myself but hope this method helps:
