Trigger not sending, or gameobjects already populated?

Hi,

I'm trying to make a small game where a pig 'eats' coins. I have a prefab with an empty parent (myCoinParent for location), a coin (coin), and another empty (myCoinTarget) that the pig uses to line itself up to the right location. I'm trying to get it so that the trigger will send the object information to the pig's script, which will then be used to zero in on the proper location, trigger the respective animators, and then delete the coin when the animation finishes. As it stands the scripts I have work fine for a single coin, but the script does nothing (or bugs out) after the first one.

Having made the gameobjects public on the pig (tankcontroller.cs), I can see that the GameObjects are already populated before the trigger. They definitely shouldn't be. I'm really at a loss for what I'm doing wrong, so any help is appreciated.

(apologies in advance for newbie spaghetti code)

Code (csharp):

1.  
2. public class Collectables : MonoBehaviour {
3.  
4.     public int totalCollected;
5.     public float rotateSpeed = 20000f;
6.     public TankController myTankController;
7.  
8.  
9.     void Start () {
10.        
11.     }
12.    
13.     // Update is called once per frame
14.     void Update () {
15.         gameObject.transform.Rotate(Vector3.up * Time.deltaTime * rotateSpeed);
16.        
17.     }
18.  
19.     private void OnTriggerEnter(Collider other)
20.     {
21.         SendStuff(gameObject);
22.     }
23.    
24.     public void SendStuff(GameObject coin)
25.     {
26.  
27.             coin = gameObject;
28.             myTankController.coin = coin;
29.  
30.             GameObject myCoinParent = gameObject.transform.parent.gameObject;
31.             myTankController.myCoinParent = myCoinParent;
32.  
33.             GameObject myCoinTarget = gameObject.transform.Find("myCoinTarget").gameObject;
34.             myTankController.myCoinTarget = myCoinTarget;
35.        
36.  
37.     }
38.  
39.  
40. }

here's the (much longer and poorly coded) character/animator controller I'm working on:

12.     float rotSpeed = 3f;
13.     float speed = 0f;
14.     bool moving = false;
15.     bool movingConnectEmpties = false;
16.     public bool connectedEmpties = false;
17.     bool shootingCoins = false;
18.     public float offsetMagnitude = 0;
19.     float runDistance = 5f;
20.     public Animator myCoinAnimator;

any help would be appreciated!

 

update: I have three coins in my scene right now, and I've realized that if I approach either of the latter two, the pig will still run back to the location of the first one. This occurs even after the first coin is destroyed. But the first script above (Collectables) is on the prefab itself, so I have no idea what's causing this
