one bullet at a time
hi, trying to make an fps game here but i have got a little problem, im using the an uppgraded varsion of the Machine gun script from the fps tutorial, but im using it with a handgun so i thougt i would be better if it fires one bullet every time i hit the mouse button instead of shooting ine bullet every second as i have it now, can anyone help me (obviously i dont know the first thing about programming)

I guess you could do something like this?
function Fire ()
{
if (Input.GetButtonDown("Fire"))
FireOneShot();
}
i dont really understand, where in the script should i put this?
Well I don't understand your script either. There's no code that detects input so I am not sure where to put the input test. Are you calling Fire() continously? You wanted to fire each time you pressed a button, and from my best effort to understand your code, that's sort of how it should look. Each time you press the button "Fire" down, it fires one shot.
maby i should use the unmodified script? it will still have the same problem but no one have bin poking around in it.
