Step 1: Getting Things Running

• Create a new folder called TestGame (or whatever) inside the BBDK/Games folder.
• Create 2 more folders inside Games/TestGame: Scripts and Resources. These folders aren't necessary, they're just for organization.
• Create a file called "Main.cs" inside TestGame/Scripts.

using GameAPI;
using GameAPI.BudgetBoy;
using ResourceLibrary;

namespace Games.TestGame
{
    [GameInfo(
        Title = "TestGame",
        AuthorName = "YourName",
        AuthorContact = "your@email.com",

        UpdateRate = 60
    )]
    [GraphicsInfo(Width = 256, Height = 192)]
    public class Main : Game
    {

    }
}

You should now be able to choose your game from the drop down list when running the BBDK. Nothing will happen yet though, it should just show a black screen. If you are on Linux or Mac OS X and get a SystemException, make sure you have installed the Mono runtime.

• We'll now create a new Stage for the game. Stages are like Unity's Scenes, used to represent different levels or modes in a game. Create GameStage.cs in the TestGame/Scripts folder:

using System.Collections;
using System.Collections.Generic;

using GameAPI;
using GameAPI.BudgetBoy;

namespace Games.TestGame
{
    public class GameStage : Stage
    {
        // called when this stage is created
        public GameStage(Main game) : base(game)
        {
            Debug.Log("GameStage created");
        }

        // called when this stage is entered
        protected override void OnEnter()
        {
            Debug.Log("GameStage entered");
        }

        // called each tick
        protected override void OnUpdate()
        {
            base.OnUpdate();
        }

        // called when this stage is rendered
        protected override void OnRender()
        {
            base.OnRender();
        }
    }
}

• Edit Main.cs so that the game starts with the GameStage.

public class Main : Game
{
    protected override void OnReset()
    {
        SetStage(new GameStage(this));
    }
}

• Turn on the BBDK's console (the >_ button on the left side) so you can see the debug messages and know that the game is in fact working, despite nothing showing up.
