[edit] DarkBASIC

Darkbasic is a programming language that specializes in the creation of games. It can create both 2D and 3D games using a lot less code than the equivalent program would take by using more powerful languages such as C++ due to the included libraries. It is often referred to as DarkBASIC Classic to avoid confusion with DarkBASIC Professional. It consists of an IDE, Debugger and Compiler, and an engine built on DirectX 7. The compiler emitted Bytecode that is appended to an interpreter to create a stand alone executable. The current version is 1.2.0, released October 2007. Since the introduction of Darkbasic Professional, The Game Creators have stated that there will be no further updates to the language, although it will still be sold.

[edit] DarkBASIC Professional

Main article: DarkBASIC Professional

Developed as a replacement for DarkBASIC. As with DarkBASIC it consisted of an IDE, debugger and compiler. Unlike DarkBASIC, the DarkBASIC Professional compiler outputs Machine Code. The engine originally used DirectX 8.1 but has been updated to use DirectX, 9.0c. The language is essentially the same as DarkBASIC with a few additions. Notably types which allow combining simple data types into a composite data type similar to Structs in C. Other features include the use of shaders, 3D maths commands and vertex editing commands. The current version is 6.5 released 1. March 2007.

[edit] Plugin architecture

Plugins allow extra commands to be added to the language. Plugins are DLLs with an embedded string resource detailing the routines implemented in the dll^[1]. At compile time the compiler bundles the relevant plugin dlls into the executable^[2].

Interestingly built-in commands are also implemented in the same way. This allows third party plugins access to built-in commands by calling the correct function in the relevant dll.

Currently available plugins provide a wide range of addition commands from language extensions and utility functions^[3]. to integration with physics engines^[4] or accessing a Database.

[edit] Dark Game SDK

The DarkBASIC Professional engine packaged up for use with Visual C++ or Microsoft .NET. It has been publiscised as released with Visual C++ 2008, and is specially designed with intellisense for this edition. The DarkGDK can be used with Visual C++ and is available as a free download, and the DarkGDK.Net product is available for purchase and allows access to the DarkBASIC engine from C# and VB.NET.

[edit] Dark Game SDK^[7]

 
#include "DarkGDK.h"

void DarkGDK ( void )
{
        // set sync on and sync rate to 60 frames per second
        dbSyncOn   ( );
        dbSyncRate ( 60 );

        // make a cube
        dbMakeObjectCube ( 1, 10 );

        // loop until the escape key is pressed
        while ( !dbEscapeKey ( ) )
        {
                // update screen
                dbSync ( );
        }
}
