unity on-off character hiding and component disabled

This answer quotes ChatGPT

To do this, you need to write code in the game engine. Here are some general ideas, which can vary depending on the game engine and programming language you are using.

First, you need to create a character object and a vehicle object. When the player presses the "F" key, detect if the character has collided with the vehicle, if so, set the character's position to the vehicle position, and hide the character object, enable the vehicle component, and disable the character component. At this point, the player can control the vehicle.

When the player presses the "F" key again, detects whether the vehicle currently controlled by the player has collided with another vehicle, if so, sets the player's position to the vehicle position, displays the character object, disables the vehicle component, and enables the character component.

Here is an example of a C# script implementation based on the Unity game engine, assuming that characters and vehicles are assigned tags of "Player" and "Car", respectively:

public class CarController : MonoBehaviour
{
    public GameObject player;
    public GameObject car;

    private bool isDriving = false;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.F))
        {
            if (!isDriving && Vector3.Distance(player.transform.position, car.transform.position) < 2.0f)
            {
                isDriving = true;
                player.SetActive(false);
                car.GetComponent().enabled = true;
                car.GetComponent().enabled = false;
            }
            else if (isDriving && Vector3.Distance(player.transform.position, car.transform.position) < 2.0f)
            {
                isDriving = false;
                player.SetActive(true);
                car.GetComponent().enabled = false;
                car.GetComponent().enabled = true;
            }
        }
    }
}
