[Chris12345]

how can i convert this to C#

#pragma strict

var spawnPoints : Transform[];  // Array of spawn points to be used.
var enemyPrefabs : GameObject[]; // Array of different Enemies that are used.
var amountEnemies = 20;  // Total number of enemies to spawn.
var yieldTimeMin = 3;
var yieldTimeMax = 5;  // Don't exceed this amount of time between spawning enemies randomly.
var i : int;
public var theFsm : PlayMakerFSM;

function Spawnblock() 
{ 
    for (i=0; i<amountEnemies; i++)
    {
      yield WaitForSeconds(Random.Range(yieldTimeMin, yieldTimeMax));  // How long to wait before another enemy is instantiated.
 
      var obj : GameObject = enemyPrefabs[Random.Range(0, enemyPrefabs.length)]; // Randomize the different enemies to instantiate.
      var pos: Transform = spawnPoints[Random.Range(0, spawnPoints.length)];  // Randomize the spawnPoints to instantiate enemy at next.
 
      Instantiate(obj, pos.position, pos.rotation); 
}}
