Selecting a Car for a scene!

Hello, I’ve made a menu wherein user is asked to select a car and the scene or the race starts with that car, what I’ve done now is to create different scenes and on clicking that car, I’m opening that scene. But i feel it makes the game size more, and I believe there’s a way to place all the cars in a single scene and only enable the one which the user selects, this can be done by scripting I suppose just like switching the camera. Any idea anybody?

You can prevent GameObjects from being destroyed when you change a scene. So for example if you have spawned all the cars in the car selection scene, then you let the player select which car they want to use.

if(selectedCar != null)
{
    DontDestroyOnLoad(selectedCar);
    // Here you can load the next scene or whatever it is you want to do.
}

That way the car the player selected wont get destroyed and it will be available even after you have changed your scene. So then you just get that car via a script and use it.
So then you can re-use the same scene no matter what car the player chooses and you don’t need to have a car present in the scene, since the player brings it along from the car selection screen.
