Kick a Ball - Add Force?

Hey! So I am working on this football game:http://pixelpizza.de/wordpress/?p=297

and currently i am stuck at the "kick a Ball" part. kicking works great so far and looks like this:


what i want do do now is, using AddForce/Impulse in a way that the ball is flying into the direction of the kick/where i kick it as soon as the feet collides with the ball or the ball is near enough to the player & the kick button is pressed.

thanks!

 

so, i tried it a little bit on my own and my current code looks like this:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Dribble : MonoBehaviour {
5.  
6.     public float dist = 0;
7.     public Transform target;
8.     public Rigidbody rb;
9.     public float forward; //150000
10.     public float up;//2000
11.  
12.     // Use this for initialization
13.     void Start () {
14.         rb = GetComponent<Rigidbody>();
15.    
16.     }
17.    
18.     // Update is called once per frame
19.     void Update () {
20.         dist = Vector3.Distance(target.position, transform.position);
21.         if (dist  < 0.9f)
22.         {
23.             rb.AddForce((target.transform.position - transform.position).normalized * forward * Time.smoothDeltaTime);
24.         }
25.  
26.         if (Input.GetKey(KeyCode.E) && dist  < 2.0f)
27.         {
28.             rb.AddForce(Vector3.up * up);
29.             rb.AddForce((transform.position + target.transform.position).normalized * forward * 0.02f);
30.         }
31.    
32.     }
33. }
34.  

the code is placed on the ball, "public Transform target;" is a invisible gameobject infront of the player
in theorie it looks pretty good.



but there are some problems.
1. the ball is not flying in the right direction. it always moves to the same direction

2. the ball is "wobbeling" weirdly infront of the player
