What is wrong with this rigidbody?

Questions & Answers

So im just trying to make a ball move with constant velocity in the x direction, the thing is when i write a certain velocity it will work normally:

public Rigidbody thisRigidbody;

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

void FixedUpdate () {
    thisRigidbody.velocity = new Vector3(5, thisRigidbody.velocity.y, thisRigidbody.velocity.z);
}

But i want to modify that velocity through a float variable (playerSpeed):

public float playerSpeed = 0;
public Rigidbody thisRigidbody;

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

void FixedUpdate () {
    thisRigidbody.velocity = new Vector3(playerSpeed, thisRigidbody.velocity.y, thisRigidbody.velocity.z);
}

the weird thing is even when i use playerSpeed in 0 like in the code, the ball will move in x anyways in a certain velocity, and when i modify the playerSpeed to some other value, it still moves in that velocity,
idk if i’m missing something help guys

Well the only possible mistake I can guess is that you are changing value of playerSpeed in the script itself and not inspector. Once you set the value of a public variable and set it to something, and then if u change the value of that variable in inspector then the Compiler will always take the value which is set in the inspector and will never look back to value which you set in script even if you change it.
So make sure you are changing value of playerSpeed in the inspector.

thank you man, i had no idea it was totally necessary to check the public variables in the inspector, for some reason playerSpeed was set to 10 in the inspector by default
