CGALIB 1 Graphics Library

Some of the games on this site are based on the CGALIB 1 graphics library. CGALIB 1 is a relatively fast, specialised C graphics library. It targets the CGA graphics adapter, specifically the 4-colour 320x200 CGA graphics modes, although it will also emulate these modes on the 640x200 screen using dithering, for clarity on monochrome devices. For speed it organises the screen into 4x2 pixel cells, making it more suitable for turn-based games than for action games that require ... (read more...)

KEYLIB Keyboard Library

Some of the games on this site use KEYLIB as their keyboard input library. KEYLIB is a small, simple library for reading a standard IBM PC/XT/AT keyboard. As well as the usual ASCII keypress functions, it allows scanning any key by scancode to check its key up/key down status. This means you can use it to check for shift keys used alone, or combinations of non-shift keys. KEYLIB is provided in source and binary formats for the OpenWatcom ... (read more...)

CGALIB 2 Game Library

All of the games on this site since Star Cadre: Combat Class are based on the CGALIB 2 game library. CGALIB 2 is a collection of libraries, including a relatively fast, specialised C graphics library, a keyboard library, and a sound library. For graphics it targets the CGA graphics adapter, specifically the 4-colour 320x200 CGA graphics modes, although it will also emulate these modes on the 640x200 screen using dithering, for clarity on monochrome devices. For speed it ... (read more...)

LevelMap Level Generator Library

LevelMap is a simple C library for generating small dungeons and similar levels for turn-based games. Features include the ability set dimensions of the maps or leave them random, generation of both rooms and corridors, and if desired, connected textures. Levels can be up to 256 blocks in size, of dimensions anywhere from 28x9 through 16x16 to 9x28. LevelMap does not directly handle the graphics, but does generate the data, including what is needed to show connected textures. ... (read more...)
