8.  
9.     static byte nombre4 = 135;
10.     byte a=0;
11.     GameObject[]liste1 = new GameObject[nombre4];
12.     float distance = 70f;
13.     public Transform prefab ;
14.  
15.  
16.  
17.     // Use this for initialization
18.     void Start () {
19.         for (int i=0, x =0,y=0,z=0 ; i < nombre4; i ++) {
20.             liste1 [a] = Instantiate (Resources.Load("Flame"), new Vector3 (x * distance, y * distance, z * distance), Quaternion.identity)as GameObject;
21.             x+=5;
22.             y+=5;
23.             z+=5;
24.             a++;

It simply means that you have no Prefab called "Flame" in your resources folder?

 

Hello MysteriX,
I use the prefab Flame , default resource of Unity packages
Standart assets => particles => fire => "Flame"

 

I do not have unity here in the moment. But I think you have to copy it to an resources folder. This folder can be where ever you want.
