C# console App - gameloop / multiple object

Question

as the title says im currently working on a Console Game in c#. The problem is, i fail to make a working gameloop everytime... Also I have a Problem with "spawning" multiple objects like in this case bullets or enemys (Im still new to c# and also stakoverflow ;P)

I hope u can help me getting it working!! :)

Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the **shortest code necessary to reproduce it in the question itself**. Questions without a clear problem statement are not useful to other readers. See: [mcve] — Enigmativity, Jun 22 '18 at 07:24
Just a small bit of help, here's an improved `PowerUp` class: `class PowerUP { private Random rnd = new Random(); public string WhichUP() => ":O^~".Substring(rnd.Next(4), 1); }`. — Enigmativity, Jun 22 '18 at 07:27

For the gameloop you can create something like Unity3D, funcion start that creates everything(Where you do the things necessary for looping) and then a Update function " while(!end) Update();"

This

   bool end  = false;
   static void Main(string[] args)
{
  //Things before the Loop
  //Instantiate player etc
  while(!end) Update();


}

   void Update(){//Loop
  // When the game is finished End = true

 }
