Coin magnet like effect, transform.translate help needed

Hello, i want the magnet effect on my coins, for that i want to move it so that it moves towards my hero, intersect him and go forward...

see this image >> http://imgur.com/ydzS1U2



I need movement across z[guy is running in z +ve direction] and x[left right] and this is the script attached to the coin , seee in void start() and guide me the right movement..

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class bottleCollector : MonoBehaviour {
5.    
6.     public static int _currentBottlesCollected=0;
7.     public int magnetDistance = 10;
8.    
9.  
10.     // Use this for initialization
11.     void Start () {
12.         //do -90 to make it straight
13.     transform.Rotate(-90, 0, 0);
14.         float playerpos_z= characterScript.hero_z_position;
15.         float bottlepos_z= transform.position.z;
16.         float disdiff_z = bottlepos_z - playerpos_z;
17.        
18.         float playerpos_x= characterScript.hero_x_position;
19.         float bottlepos_x= transform.position.x;
20.         float disdiff_x = bottlepos_x - playerpos_x;
21.        
22.         //transform.Translate(disdiff_x,transform.position.y,disdiff_z);
23.         transform.Translate(Vector3.forward * Time.deltaTime);
24.        
25.         //Debug.Log("Player pos z="+playerpos_z+",Bottle pos z="+bottlepos_z+",diff z="+disdiff_z);
26.         //Debug.Log("Player pos x="+playerpos_x+",Bottle pos x="+bottlepos_x+",diff z="+disdiff_x);
27.     }
28.    
29.     // Update is called once per frame
30.     void FixedUpdate () {
31.         float a;
32.         float b;
33.         a = characterScript.hero_z_position;
34.         b = transform.position.z;
35.         //Debug.Log(a);
36.     //transform.Translate(-Vector3.forward * Time.deltaTime);
37.         if(characterScript.hero_z_position>transform.position.z){
38.             //Debug.Log("bottle is at the back");
39.             Destroy(gameObject);
40.         }
41.     }
42.    
43.    
44.     void Update(){
45.        
46.        
47.         //Vector3 bottlepos = transform.position;
48.         //Debug.Log(playerpos);
49.        
50. //        if(Vector3.Distance(playerpos, transform.position) < magnetdistance){
51. //   transform.position = Vector3.Lerp(transform.position, player.transform.position, Time.deltaTime);
52. //  }
53.     }
54.  
55.     void OnTriggerEnter(Collider other) {
56.         if(other.gameObject.tag == "Player"){
57.             _currentBottlesCollected=_currentBottlesCollected+1;
58.             scoreHandler.currentgameBottlesCollected = _currentBottlesCollected;
59.         //  Debug.Log(scoreHandler.currentgameBottlesCollected);
60.         //  Debug.Log(".."+_currentBottlesCollected);
61.             Destroy(gameObject);
62.     }}
63.    
64.      void OnBecameInvisible() {
65.         //Debug.Log("Invisible bottle");
66.         Destroy(gameObject);
67.     }
68. }
69.  

But if i try to add this line of code in my FixedUpdate then i get these errors-

Code (csharp):

1. transform.position = Vector3.Lerp(transform.position, characterScript.transform.position, Time.deltaTime);

1. Assets/scripts/bottleCollector.cs(32,87): error CS0120: An object reference is required to access non-static member `UnityEngine.Component.transform'
2. Assets/scripts/bottleCollector.cs(32,46): error CS1502: The best overloaded method match for `UnityEngine.Vector3.Lerp(UnityEngine.Vector3, UnityEngine.Vector3, float)' has some invalid arguments
3. Assets/scripts/bottleCollector.cs(32,46): error CS1503: Argument `#2' cannot convert `object' expression to type `UnityEngine.Vector3'


This is my characterScript incase you wish to see- http://pastebin.com/Mi1taSYa

 

Hi, it strikes me as characterScript doesn't inherited from MonoBehaviour class.

Try to write this:

Code (csharp):

1. transform.position = Vector3.Lerp(transform.position, characterScript.pos, Time.deltaTime);

UPD.: Sorry, I didn't see characterScript code before. It's realy inherited from MonoBehaviour. In any case try to rewrite code as in my example (I correct it a little bit).

 

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class bottleCollector : MonoBehaviour {
5.        
6.         public static int _currentBottlesCollected=0;
7.         public int magnetDistance = 10;
8.         public GameObject soldier;
9.  
10.         // Use this for initialization
11.         void Start () {
12.                 soldier = GameObject.Find("Soldier");
13.                 //do -90 to make it straight
14.         transform.Rotate(-90, 0, 0);
15.                 float playerpos_z= characterScript.hero_z_position;
16.                 float bottlepos_z= transform.position.z;
17.                 float disdiff_z = bottlepos_z - playerpos_z;
18.                
19.                 float playerpos_x= characterScript.hero_x_position;
20.                 float bottlepos_x= transform.position.x;
21.                 float disdiff_x = bottlepos_x - playerpos_x;
22.                
23.                 //transform.Translate(disdiff_x,transform.position.y,disdiff_z);
24.                 transform.Translate(Vector3.forward * Time.deltaTime);
25.                
26.                 //Debug.Log("Player pos z="+playerpos_z+",Bottle pos z="+bottlepos_z+",diff z="+disdiff_z);
27.                 //Debug.Log("Player pos x="+playerpos_x+",Bottle pos x="+bottlepos_x+",diff z="+disdiff_x);
28.         }
29.        
30.         // Update is called once per frame
31.         void FixedUpdate () {  
32.                
33.                
34.                 //transform.position = Vector3.Lerp(transform.position, soldier.transform.position, Time.deltaTime);
35.                
36.                 float a;
37.                 float b;
38.                 a = characterScript.hero_z_position;
39.                 b = transform.position.z;
40.                 //Debug.Log(a);
41.         //transform.Translate(-Vector3.forward * Time.deltaTime);
42.                 if(characterScript.hero_z_position>transform.position.z){
43.                         //Debug.Log("bottle is at the back");
44.                         Destroy(gameObject);
45.                 }
46.         }
47.        
48.        
49.         void Update(){
50.                
51.

57. //  }
58.         }
59.  
60.         void OnTriggerEnter(Collider other) {
61.                 if(other.gameObject.tag == "Player"){
62.                         _currentBottlesCollected=_currentBottlesCollected+1;
63.                         scoreHandler.currentgameBottlesCollected = _currentBottlesCollected;

66.                         Destroy(gameObject);
67.     }}
68.        
69.          void OnBecameInvisible() {
