How would I make addforce only apply when a ball is touching an object on my character

I want to make a ball launch from a catapult mechanism when i press the space bar. How would i make it so that it has to be touching an object on the character so that it would move. Also how would I make it that it goes in the direction that the character is facing. This is my code so far. I am using C# using UnityEngine; using System.Collections;

 public class shooting : MonoBehaviour {
     Animator anim;
     // Use this for initialization
     void Start () {
         anim = GetComponent<Animator> (); 
     
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetKey (KeyCode.Space))
                         rigidbody.AddForce (Vector3.right * 100);
 
         if (Input.GetKey (KeyCode.Space))
             rigidbody.AddForce (Vector3.up * 70);
 
 
 
     
     }
 }

to move the ball at the direction the character facing use transform.forward vector instead of Vector3.forward.

Another way is to use rigidbody.AddForceRelative(Vector3.forward * 100f) - it will cause the same result (applies force in forward direction of the character).

Also its better to use just one AddForce / AddForceRelative call:

rigidbody.AddForceRelative(Vector3.forward 100f + Vector3.up 70f)
