RigidBody,velocity not working on Start method

Questions & Answers

Hi everyone,

I am pretty noob in Unity but i am having some trouble that i don´t understand. I saw some tutorials where they assign a initial velocity to a rigidbody, and i am doing the exactly same thing and it´s not working. They do it in the Start() method but for me only works on the Update method. This is really a problem for me because i need it on the Start method in order to not assinging the same velocity in every frame.

Like this doesnt work:

public class testVelocity : MonoBehaviour {
    public Vector3 initialVelocity;
    public Vector3 initialAngularVelocity;

    private Rigidbody rigidBodyBall;
	// Use this for initialization
	void Start () {
        rigidBodyBall = GetComponent<Rigidbody>();
        rigidBodyBall.velocity = initialVelocity;
        rigidBodyBall.angularVelocity = initialAngularVelocity;
    }
	
	// Update is called once per frame
	void Update () {
        
    }
}

It only works like here:

public class testVelocity : MonoBehaviour {
    public Vector3 initialVelocity;
    public Vector3 initialAngularVelocity;

    private Rigidbody rigidBodyBall;
	// Use this for initialization
	void Start () {
        rigidBodyBall = GetComponent<Rigidbody>();
        
    }
	
	// Update is called once per frame
	void Update () {
        rigidBodyBall.velocity = initialVelocity;
        rigidBodyBall.angularVelocity = initialAngularVelocity;
    }
}

Most probably there is something blocking your object.
If you dont mind one frame you can try this:

[RequireComponent(typeof(Rigidbody))]
public class testVelocity : MonoBehaviour {
     public Vector3 initialVelocity;
     public Vector3 initialAngularVelocity;
 
     private Rigidbody rigidBodyBall;
     IEnumerator Start () {
         rigidBodyBall = GetComponent<Rigidbody>();
         yield return null;
         rigidBodyBall.velocity = initialVelocity;
         rigidBodyBall.angularVelocity = initialAngularVelocity;
     }
 }
