If you are using motors then I made something that I think should work for you.
You can change the value from one to something else if you don't want it to spin at full speed. You may also have to change which motor it is that gets multiplied by -1 if it goes backwards. You should also add the motors to the finish.vi but I didn't show that.
I have no idea what button is the trigger on an attack 3. You can either look that up or just do trial and error. It may even be that the trigger isn't a button and is an analog signal which would probably make it one of the axis values.
If you want it to make it so that every time you hit the button it changes between on and off instead of having to hold it you can use a toggle.vi which I have attached. To use this you just put it in between the button and the select.
I hope this works I am new to this stuff too but I think that this should do what you want it to.
