Roll-a-ball

Hello, Im tryin unity for the forst time and I started with making Roll-a-ball project acording official tutorial. I stacked at moving the ball...

using UnityEngine;
using System.Collections;

public class PlayerController: MonoBehaviour
{
public Rigidbody playerRigidBody;


void Fixedupdate ()
{
float moveHorizontal = Input.GetAxis ("Horizontal");
float moveVertical = Input.GetAxis ("Vertical");

Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
playerRigidBody.AddForce (movement);

}
}

The ball doesnt move...
pls help

 

You need to change your function's name to FixedUpdate () instead of Fixedupdate().

 

Also,
Where is playerRigidBody assigned a value ??

 

As above you havent assined Rigidbodyplayer a value. So at the moment you are asking addforce to use Rigidbodyplayer as a ridigidbody without calling the component for Rigidbody.

Try entering this code above FixedUpdate() << don't forget to caps the U in update

Code (csharp):

1. void Start()
2. {
3.       playerRigidBody = GetComponent<RigidBody>();
4. }
5.  

Hopefully this will fix your issue.

 

He's using a public variable for rigid body. You can assign it from outside the script.

 

No. He is using a public declaration. ( which just determines a memory placeholder for a variable)
I asked how/where he was assigning a value to that field.

 

By dragging the ball/object into the form field in the properties panel

 

were you able to get the ball moving or are you still looking for some help?

 

Also for the tutorials that the learn team put up there is Q&A threads under the teaching section made for each specific tutorial. Makes it alot easier for the tutors to find posts related to their tutorials

have a look over at the RollABall Q&A thread if need further info.
