Help with multiple collision

Questions & Answers

Hello,

I am having an issue with detecting only one collision. I have a game where there is a standard asset FPS controller and two cars. By the door there is a trigger, and when my character is inside the collider box I can press ‘e’ and he will get in the car.

When you get in the car, a car driving script is activated so I can control the car.

If I park two cars right next to each other and stand in-between them, my character gets in both of the cars. And both scripts are activated and I can drive both the cars.

if (playerInRange == true){
	if (Input.GetKeyDown("e")){
		if (playerInVehicle == false){
			playerInVehicle = true;
			Char.active = false;
			Char.transform.parent = gameObject.transform;
			
			//Car.GetComponent(AudioSource).enabled = true;
			Car.GetComponent(CarEngine).enabled = true;
			
			//Cam.GetComponent(MouseOrbit).target = CamTarget2;
			// Disable mouse cam, and enable car cam.
			CarCam.GetComponent(CarCamera).car = CamTarget2;
			CarCam.GetComponent(CarCamera).enabled = true;
			
			
		}
		
		else if (playerInVehicle == true){
			playerInVehicle = false;
			Car.GetComponent(CarEngine).enabled = false;
						
			Char.active = true;
			Char.transform.parent = null;
			Char.transform.position.y += 0.04;
			Char.transform.rotation.x = 0.00;
			Char.transform.rotation.y = Car.transform.rotation.y;
			Char.transform.rotation.z = 0.00;
		}
	}		
}

How can I make it so that only one script gets activated, and not both??

You want a variable on you player that records if they are in any car and prevents entering a new car.

By rights this entire script should belong to the player, not the vehicle. The player should attempt to enter. The vehicle should then either accept or reject player entry.
