Input.GetButtonDown Unknown member

I’m not seeing a fire effect happen so I put a breakpoint in to see and the debugger is giving me a Input.GetButtonDown Unknown member: GetButtonDown error at the if with Input.GetButtonDown. This seems to happen intermittently. When I go to the declaration of Input, it seems to be right (with a GetButtonDown), but

	void Update () {
		if (canThrow) {
			if (Input.GetButtonDown("Fire1")) {
			.
			.
			.
			}
		}
	}

I guess you called your class Input, and since your Input class doesn’t have a GetButtonDown function, Unity doesn’t know what you’re talking about.
