Unity Script help for on/off switch code.

I have been trying to create a code for entering and exiting a vehicle. I have been using the following:

`var carCam :Camera;
var walkCam : Camera;
var on :boolean;

function Update()
{
if(Input.GetButtonUp(“action”))
{
on=true;
car.GetComponent(carController).enabled=true;
carCam.enabled=true;
walkCam.enabled=false;
}
else
{
on=false;
car.GetComponent(carController).enabled=false;
carCam.enabled=false;
walkCam.enabled=true;
}
}
`

when game starts, walkCam is on first. when i press the action key it switches to the car, but when i press action key again, it just stays on car. I am not the best at scripting and i have been searching for weeks as well as reading the scripting reference nad no luck, im not sure what im doing wrong. How can i make it so i can enter and exit a car?

You need to set up a toggle switch by negating a boolean flag each time your action button is pressed. Like so (cleaned up your script also):

var carCam : Camera; 
var walkCam : Camera; 
var on : boolean = false;
var toggle : boolean = false;

function Start () {
	carCam.enabled = false;
	car.GetComponent(carController).enabled = false;
}

function Update() { 
	if(Input.GetButtonUp(KeyCode.K)) { 
		if (!toggle) {
			toggle = true;
			on = true; 
			car.GetComponent(carController).enabled = true; 
			carCam.enabled = true; 
			walkCam.enabled = false; 
		} else {
			toggle = false;
			on = false; 
			car.GetComponent(carController).enabled = false; 
			carCam.enabled = false; 
			walkCam.enabled = true;
		}
	}
}

Next time, make sure to format your code correctly by highlighting the full code and pressing the 101010 button.

Hope that helps, Klep
