There is a way to set a max to the resultant force in a object ?

Using as example my project:
I wanted to control my camera (in game) through de “w,a,s,d” keys, so I used the “add.Force” to make it move:

public float speed;
public float olhada;
private Rigidbody rb;

void Start () {
    rb = GetComponent<Rigidbody>();
}


void FixedUpdate () {
    float moveHorizontal = Input.GetAxis("Horizontal");
    float moveVertical = Input.GetAxis("Vertical");
   
    Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
     rb.AddForce(movement * speed);
    
}

, but a issue that I saw is that it continue to add more and more force to the camera so it reaches lightspeed if you hold the keys for to much. So to solve it I thought “Why I dont use “Transfor.position” instead?”, and then I made this:

public float speed;
public float olhada;
private Rigidbody rb;

void Start () {
    rb = GetComponent<Rigidbody>();
}


void FixedUpdate () {
    float moveHorizontal = Input.GetAxis("Horizontal");
    float moveVertical = Input.GetAxis("Vertical");
   
    Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
     transform.position += movement;
    
}

,which solved the problem of the camera getting to fast, but , instead of “Add.Force”, it wasn’t a force, so colisions didn’t stop the camera to pass through wall and, basicly, everything.
So, after these tries I saw that the “Add.Force” method was better but I had no idea of how I could make a limit to the camera move like in the “Transfor.position”. And here comes my question:

There is a way to set a max to the resultant force in a object ?

(Sorry if my description got to big (and borring), but I wanted to give the maximum of details I could)

I think what you want to do is check if it’s at a certain speed then not add anymore force…

//maxSpeed would be a variable you add...
if (rigidbody.velocity.magnitude < maxSpeed)
{
	//forceToAdd is whatever force you're adding
	rigidbody.AddForce(forceToAdd);
}

//or Option #-----------------------------

rigidbody.AddForce(forceToAdd);
if (rigidbody.velocity.magnitude > maxSpeed)
{
	var direction = rigidbody.velocity.normalized;
	rigidbody.velocity = direction * maxSpeed;
}
