An open source modern minimal game cross platform gaming library

Bare Game is a open source modern minimal game cross platform gaming library. It was conceived to take the SDL 2.0 game library and pair it with the Free Pascal Compiler, combining Free Pascal's write once compile anywhere philosophy with with SDL 2.0 ability to empower games on every platform. Bare Game wraps SDL 2.0 functions and defines in an extremely easy to reuse class library. It takes care of all the boilerplate plumbing required to get a game started and running on a variety of platforms, empowering you, the game creator, to focus on what you want to do, designing your game.

Install

Install SDL 2 on your system. Ubuntu users type sudo apt get install libsdl2-2.0-0. Windows users download SDL 2, extract the zip file, and place SDL2.dll in your C:\Windows\System32 folder.

Install Free Pascal fixes 3.0 and Lazarus, either using getlazarus.org or make it yourself.

To get Bare Game, if you have git installed you may type:

git clone https://github.com/sysrpl/Bare.Game.git

Otherwise download a zip file from github and extract it.

Open Lazaurs, from the main menu select "Packages | Open Package File" and browse to "Bare.Game/source/barerun.lpk". In the packge window press compile.

From the Lazarus main menu select "Packages | Open Package File" and browse to "Bare.Game/tools/design/baredsgn.lpk". In the packge window press "Use | Install". Lazarus will rebuild itself.

If you recieve and error in splash.pas with a value of fsBlack, change it to clBlack, save the file, and repeat the step above.

When Lazarus restarts, select "File | New ... | Project | Game Project" from the main menu. You should see this skeletal program listing.

program Game1;

{$mode delphi}

uses
  Bare.Game;

{ TWindow1 }

type
  TWindow1 = class(TWindow)
  protected
    procedure Logic(Stopwatch: TStopwatch); override;
    procedure Render(Stopwatch: TStopwatch); override;
  end;

procedure TWindow1.Logic(Stopwatch: TStopwatch);
begin
  { Place your game logic code here }
end;

procedure TWindow1.Render(Stopwatch: TStopwatch);
begin
  { Place your game rendering code here }
end;

begin
  Application.Run(TWindow1);
end.

Press F9 to run the example. You should see a black window with the title "TWindow1". Next open the project "Bare.Game/examples/draw/draw.lpi" and press F9. You should see a window with an animated neon cursor and some instructional text. If both of those test pass, you've got a working install of Bare Game.
