Question by Eradan · Jun 13, 2016 at 12:22 PM · rigidbody physics

Rigidbody stuttering movement

I'm working on a racing game prototype. I have 7 NavMesh agents scaled cubes and 1 player. These 8 objects have a ridigbody component (but I think the agents ignore the rigidbody). Everything moves smoothly but the player. I've made a video of it, I hope you can see clearly the issue:

https://youtu.be/2i5tP6Y4fwI

The last "car" moving is the player. This is the only script running in the test video:

 function Start () {
     rb = GetComponent.<Rigidbody>();
 }
 
 function FixedUpdate () {
         var grounded : boolean = true;
 
         if (Input.GetAxisRaw("Vertical") == 1 && grounded) {
                 rb.AddRelativeForce(Vector3.forward * acceleration);
         }
 
     //Brakes
     if (Input.GetAxisRaw("Vertical") == -1 && grounded) {
                 rb.AddRelativeForce(Vector3.back * acceleration);
         }
 

I thought it was a camera issue, that's why the camera is static and on top. Any idea on what's causing the stutter? Removing the rigidbody is not an option to solve this.

first of all split your script to handle input and physics separately:

input (C# sorry):

 public class car_input
 {
  private car_physics _physics;
 
  void Start()
  {
    _physics = getComponent<car_physics>();
  }
 
  void Update()
   {
    float y = Input.getAxis("vertical");
    _physics.move(y);
   }
 }

physics :

 public class car_physics
 {
  private Rigidbody _body;
  private Vector3 movement;
  private float speed = 10f;
 
  void Start()
  {
    _body = getComponent<RigidBody>();
    movement = new Vector3(0, 0, 0);
  }
 
  public void move(float v)
  {
   movement = Vector3.forward * v;
  }
 
  void FixedUpdate()
  {
   _body.velocity = movement * speed;
  }
 }

Change Interpolate parameter of rigidbody component to "Interpolate"
