Question by Oberruk · Jul 21, 2015 at 07:35 AM · physics

AddForce not working in: "rigidbody.AddForce(Input);"

I keep getting this error when I run the non-working code. Could anyone help me with this?

Assets/NewBehaviourScript.cs(17,27): error CS1061: Type UnityEngine.Component' does not contain a definition for AddForce' and no extension method AddForce' of type UnityEngine.Component' could be found (are you missing a using directive or an assembly reference?)


//Non-working code. using UnityEngine; using System.Collections;

public class NewBehaviourScript : MonoBehaviour { public float moveSpeed;

 private Vector3 input;

 // Use this for initialization
 void Start () {
 
 }
 
 // Update is called once per frame
 void Update () {
     input = new Vector3(Input.GetAxis ("Horizontal"), 0, Input.GetAxis ("Vertical"));
     rigidbody.AddForce(Input);
     print (input);
 }

}


//Working code. UnityEngine; using System.Collections;

public class NewBehaviourScript : MonoBehaviour { public float moveSpeed;

 private Vector3 input;

 // Use this for initialization
 void Start () {
 
 }
 
 // Update is called once per frame
 void Update () {
     input = new Vector3(Input.GetAxis ("Horizontal"), 0, Input.GetAxis ("Vertical"));
     print (input);
 }

}

If you are using Unity 5, consider that the APIs have changed. If you are taking code from old tutorials, things could no longer work as reported.

You should do

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

Also note input with the lower-cased i.
