Source code repository

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 (http://www.pascalgamedevelopment.com/showthread.php?32547-DelphiDoom-2-0)) were possible to get compiled with FPC, but they were some issues and/or incompatibilities. FPCDoom provides a stable and modern id-Tech1 (https://en.wikipedia.org/wiki/Doom_engine) 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 (http://www.doomarchive.com/download.asp?FileId=5583).


Have fun!

Great!

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.

Awesomesauce mate!! :)

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?

[Chebmaster]

what does that make the Quake 1 engine?
Id tech 2, making it just an earlier version of the Quake 2 engine..

You need a wad file with game data. The FPCDoom.wad file contains only additional assets to enhance the game.
You can grab the shareware wad at http://distro.ibiblio.org/pub/linux/distributions/slitaz/sources/packages/d/doom1.wad. Save it to the same folder with FPCDoom.wad & FPCDoom.exe to play.

Oh my bad. I thought you were providing some kind of a "tech demo level" yourself in provided WAD file. Didn't realize it just an extension for the original WAD file.

Any way great work. Game runs pretty smooth.
The only quirk I found is when you go for instance into Options menu -> Display Options -> Appearance and then you pres enter on Hud ... it takes you to another sub menu from where you have no way of returning back to Appearance menu but instead pressing escape brings you back to main menu. Perhaps adding additional buttons on each menu to return to the parent menu would make browsing though options menus much easier.This is especially rue since your Options menus are much more complex than the one from original game due to all additional settings available

You can go to the upper level menu using the right mouse button of by pressing backspace on your keyboard.

Nice work, brings back memories ;)
