A struct / types what ever you call em in C#!

I am creating a space shooter game. So far you have a ship that moves, and a Scrolling bg. Exciting Isn¡¯t it.

I used to program in blitz basic and they had a thing called a type that could create multiple objects with multiple similar variables. Like if I were to create 20 alien ships with there own x positions and speed, witch I gave each a random value. Each LV I would add 5 more aliens to the LV until it became impossible. How could I create a type or something similar in C#. Also how can I give a variable a random value.

Random r = new Random();
int i = r.Next(0,100);

If your gonna have to manage alot of items in an array I believe it would be better to use classes as stucts have to be boxed/unboxed when stored in an array. In context of game loop I'd assume this would cause a small hit... though I'm not 100% positive I'm correct here.

I'm not sure if you're asking how to declare a class, or a collection.

There are several kinds of types, but I think the one you want is called a class.

For example (drawing from your description),

internal class AlienSpaceship

{

  private float x;

  private float y;

  private float speed;

  // other stuff here, like properties and methods

}

The above declaration defines a new type called AlienSpaceship, which has three float-type variables. You can instantiate as many as you like.

If you wanted 5 of them, then you could declare an array, like this:

    AlientSpaceship[] ships = new AlienSpaceship[5];

    for (int i = 0; i < ships.Length; ++i)

    {

      ships[ i ] = new AlienSpaceship();

    }

You might want to start with some C# tutorials if this actually answers your question (since you'll also need to know about visibility and a bunch of other stuff). There are also forums specifically for C# questions, which is more appropriate for this sort of thing.

Hope that helps,
