Rotating object with onscreen button

Question

I'm using javascript.

I want to rotate a car with an onscreen button.

It's easy to to create a button, and easy to create a car.

It's easy to even create a car that if clicked/pushed down will rotate.

What I'm having trouble with, is creating an onscreen button that when pushed down with something like OnMouseButtonDown () will rotate the car.

What I have done is I have a car that the main camera follows. I have a button that moves with the car and is under the car in the hierarchy.

I had two ideas to solve the problem, but I don't know how to do either.

Is there any way to reference whether or not a button is pushed down in another script?

Is there any way to control another game object with a script from a different object?

If you have any other ideas to solve the problem they would also be appreciated. Thanks

You could try adding this if statement in your update method:

 if(Input.GetKeyDown("mouse 0"))
 {
     //your rotation script
 }

there is a way to control another game object with a different object's script you can do this by declaring the gameobject. for example:

 private GameObject yourobject;
 
 void Awake()
 {
    yourobject = GameObject.Find("yourgameobjectname")
 }
 
 void Update()
 {
    if(Input.GetKeyDown("space"))
    {
        yourobject.transform.position += Vector3.up // consider multiplying by time for smooth movement
    }
 }

please note that the example is written in C# , should work exactly the same in javascript with the correct context.
