if statement problem

I am making a project for the university in unity and i dont know how to define something that i want the script to make.I have made three object lists and i want when the player eats one object from the first list and one from the second list,to choose a random object from the third list and instantiate an other object in the chosen object position.The problem is if the player eats four objects from the first list and three objects from the second list to produce only three instantiate objects and vice versa, and all this gone on untill the all objects of the third list have an instantiated object in their position.The objects in the third list are about 506.

Thank you in advance,and i hope to find me a solution

here is the script that i have made so far

Code (CSharp):

1. using UnityEngine;
2. using System.Collections.Generic;
3.  
4. public class GameLogikScript : MonoBehaviour {
5.  
6.     public GameObject Eye;
7.  
8.     public static int Score = 0;
9.  
10.     bool Simulation = false;
11.  
12.     static public List<GameObject> Eyes = new List<GameObject>();
13.     static public List<GameObject> Flies = new List<GameObject>();
14.     static public  List<GameObject> Surface = new List<GameObject>();
15.  
16.  
17.     void Start ()
18.     {
19.         Eyes.AddRange(GameObject.FindGameObjectsWithTag ("EyesMolecules"));
20.  
21.  
22.         }
23.  
24.    
25.     void Update()
26.     {
27.  
28.  
29.  
30.         Debug.Log (Eyes.Count);
31.         Debug.Log (Flies.Count);
32.         Debug.Log (Surface.Count);
33.  
34.         if (Flies.Count != 0 && Surface.Count != 0)
35.         {
36.             if (Flies.Count <= Surface.Count)
37.             {
38.  
39.  
40.                 int rnd = Random.Range (1, Eyes.Count);
41.  
42.                 Debug.Log("An Eye is looking you" + Eyes[rnd]);
43.  
44.                 Instantiate(Eye, Eyes[rnd].renderer.bounds.center, Eyes[rnd].transform.localRotation) ;
45.                 Debug.Log ("Instatiate");
46.                
47.             }
48.  
49.                 }
50.         }
51.  
52.  
53.     void OnGUI()
54.     {      
55.         GUI.Label(new Rect(10, 10, 100, 20),Score.ToString());
56.        
57.     }
58. }

 

Are you asking us to help you cheat on your homework?

 

It is not a homework,it is a project that i choose to make with unity,for the multimedia class
