My Movement code does not work, help please.

Questions & Answers
1

I am trying to code C# for character movement. I have been following a tutorial, and this is the code that I ended up with.

{
void FixedUpdate ()

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

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

	Rigidbody.Addforce(movement);
}

}

I do not know what my error is but when I try to test my game play, i get an error message in Unity saying "All complier errors must be fixed before you can enter play mode. please help me.

I am using the most recent version of Unity, unity 5

The tutorial you are following was created using Unity 4. Unity 5 handles the accessing of certain components (such a Rigidbody) differently.

The easiest way to fix your code is to replace:

Rigidbody.AddForce(movement);

With:

GetComponent<Rigidbody>().AddForce(movement);

A better way would be to cache the Rigidbody component in Start(), then access the cached version thereafter. Here is tutorial’s code rewritten for Unity 5 (and caching the Rigidbody component).

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour
{
    public float speed;

    private Rigidbody Body;

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

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

        Body.AddForce(movement * speed);
    }
}

Hope this helps!
