C# addendum

Here are the C# translations you so richly deserve. Among the very few changes here is the fact that you can't individually change the x/y/z transform.position values in C# as you can in JavaScript—you have to change all three values at the same time by creating a new instance of the Vector3 class.

BombCSharp

using UnityEngine;
using System.Collections;

public class BombCSharp : MonoBehaviour {

  public GameObject prefab;

  void Update ()
  {
    transform.position = new Vector3(transform.position.x, transform.position.y - 50 * Time.deltaTime, transform.position.z);
    if(transform.position.y < 0)
    {
      Instantiate(prefab, transform.position, Quaternion.identity);
      transform.position = new Vector3(Random.Range(0,60), 50, -16);
    }
  }
}

DestroyParticleSystemCSharp

using UnityEngine;
using System.Collections;

public class DestroyParticleSystemCSharp : MonoBehaviour
{

  void LateUpdate ()
  {
    if (!particleSystem.IsAlive())
    {
      Destroy (this...
