Doom source code is written in [C89](c.md) and is about 36000 [lines of code](loc.md) long. The original system requirements needed roughly a 30 MHz [CPU](cpu.md) and 4 MB [RAM](ram.md) as a minimum. It had 27 levels (9 of which were shareware), 8 weapons and 10 enemy types.
Doom has a [deterministic](determinism.md) [FPS](fps.md)-independent physics which allows for efficient recording of demos of its gameplay and creating [tool assisted speedruns](tas.md). Such demos can be played back in high quality while being minuscule in size and help us in many other ways, for example for verifying validity of [speedruns](speedrun.md). This is very nice and serves as an example of a well written engine (unlike later engines from the same creators, e.g. those of [Quake](quake.md) games which lacked this feature).
The game only used [fixed point](fixed_point.md), no [float](float.md)!
Doom also has a [deterministic](determinism.md) [FPS](fps.md)-independent physics which allows for efficient recording of demos of its gameplay and creating [tool assisted speedruns](tas.md), i.e. the time step of game simulation is fixed (35 tics per second). Such demos can be played back in high quality while being minuscule in size and help us in many other ways, for example for verifying validity of [speedruns](speedrun.md). This is very nice and serves as an example of a well written engine (unlike later engines from the same creators, e.g. those of [Quake](quake.md) games which lacked this feature).
LOL someone created a Doom system monitor for [Unix](unix.md) systems called [psDooM](psdoom.md) where the monsters in game are the operating system [processes](process.md) and killing the monsters kills the processes.
