Building a Raycast Script for a nursing simulation

hello, i need help on the raycast for the functionally for the nursing simulator. I'm a beginner programmer and i'm trying figure out how to make it work for our game.

 

You have not said what isn't working, and you haven't used CODE tags (its the # button in the form)

 

I'm working the raycast to point to the patient's body or at least build functionality on it. I want use a sphere collider to make the body move and Building the raycast would trigger a event or make the patient move or at flash the body of it. Like i said, i'm trying to build a raycast script for nursing simulation where the patient got injured .

 

Code (csharp):

1. using UnityEngine; using System.Collections;
2.  
3. public class Raycast : MonoBehaviour {
4.  
5. public GameObject Spherecollider;
6.  
7. private RaycastHit hit;
8.  
9. float distance = 25.0f;
10.  
11. public float power = 25f;
12.  
13. // Use this for initialization
14.  
15. void Start (){
16.  
17. }
18.  
19. // Update is called once per frame
20.  
21. void Update () {
22.  
23. //Left mouse buttton
24.  
25. if (Input.GetMouseButtonDown(0))
26.  
27. {
28. Ray rayOrigin = Camera.main.ScreenPointToRay(Input.mousePosition);
29.  
30. RaycastHit hitInfo;
31.  
32. if(Physics.Raycast(rayOrigin, out hitInfo, distance))
33.  
34. { Debug.Log (“Casted a Ray”);
35.  
36. Debug.DrawLine(rayOrigin.direction, hitInfo.point);
37.  
38. if (hitInfo.rigidbody != null)
39.  
40. {
41.  
42. //Instantiate(GameObject, hitinfo.point, transform.rotation);
43.  
44. //Call out the hit information, Rigidbody, addforceposition menu, direction position of the force should be and add the variable hitInfo.rigidbody.AddForceAtPosition(rayOrigin.dir ection * power, hitInfo.point);
45.  
46. //Call Hit info, Transformation, Gameobject,render, material, color } } } } }

I've apologize if i didn't do it right before, Can you look at now where it make more sense?
