Zombie Spawn Per Round Script

 var TurnNumber : int = 1;//keeps track of the turns :P
 var SpawnPoint : Vector3;//enter the desired coordinates where the zombies should spawn here.
 
 var ZombiePrefab : GameObject;//drag your prefab gameobject of a sample zombie here, it will be copied and instantiated into the scene
 var ZombieClone : GameObject;//keep this empty, the script will fill it when a zombie is instantiated. 
 //It only holds the last spawned zombie, all before that one have to be accessed by some other method.
 
 function Update() 
 {
     if(Input.GetKeyDown(KeyCode.Space))
     {
         NextTurn();
     }
 }
 
 function OnGUI()
 {
     GUI.Label (Rect (0, 0, 50, 100), "Turn " + TurnNumber);//displays the turn number in the upper left corner.
     //GUI.Box (Rect (0, 0, 50, 100), TurnNumber);//if you want to see how the dimensions of the label above actually look, active this line of code (or just use it instead if you don't mind the box graphic)
 }
 
 
 
 function NextTurn()
 {
     TurnNumber ++;//increases the turnNumber value by 1.
     SpawnZombie();//calls the function that spawns zombies.
 }
 
 function SpawnZombie()
 {
     ZombieClone = Instantiate(ZombiePrefab, SpawnPoint, Quaternion.identity);//Spawns a copy of ZombiePrefab at SpawnPoint with default rotation.
 }

It's great, but all in one line. Could you please give a pastebucket link?
