Source code repository

• https://github.com/jval1972/FPCDoom

Features

• High screen resolutions
• External textures
• Uncapped framerate
• Automap rotation and overlay
• Dynamic lights
• Accurate software rendering (using floating point arithmetic where needed instead of fixed point)

The purpose of the project is to provide a solid code-base of the game Doom in Free Pascal Compiler.
Early versions of it's bigger brother (DelphiDoom) were possible to get compiled with FPC, but they were some issues and/or incompatibilities. FPCDoom provides a stable and modern id-Tech1 engine fully compatible with FPC.

Compile and play
My sourceforge downloads include only the source code and the compiled executable (Win32)
To run the game you must also have game data (doom.wad or doom2.wad etc).
If you do not own the original game, you can download the shareware data (doom1.wad) from here.


Have fun!

Can it be compiled for Linux or are there some Windows-only libraries in use?

It uses DirectDraw surface for blit buffer, DirectSound for sound effets and MCI for music. Al lthe system specific routines are the i_xxxxx.pas units.

Absolutely awesome although now I'm confused - if the doom/heretic engine is ID Tech 1 - and the Quake 2 engine is ID Tech 2 - then what does that make the Quake 1 engine?
