1. Summary

This project reimplements the Doom game objects as Entity-Component-System entities and reworks DoomEdNums to refer to a list of entity "templates". It uses the Rust programming language to achieve this in an efficient, but flexible and reasonable, manner.

This implementation is tailored to PRBoom+, and requires a fork/branch of the PRBoom+ UMAPINFO fork. It serves as an experiment; do not expect the result to be seamlessly playable, let alone demo compatible!

2. Roadmap

• ✓ Write wrapper header to use PRBoom+ code from Rust.

• ✓ Setup bindgen.

• ❏ Setup PRBoom+ build system for linking the component’s static library.

• Write systems that interface with PRBoom+ components:

• * [ ] Position and velocity.

• * [ ] Collision and thing interaction.

• * [ ] Health and armour.

• * [ ] Rendering.

• * [ ] Audio.

• * [ ] Projectiles and general entity spawning.

• Set up unit testing.

• * [ ] Setup a test environment to be used when testing a System.

• * [ ] Write unit tests for each system, preferably more than one per system.

• ❏ Write entity templates based on DoomEdNums.

• ❏ Rewrite core PRBoom+ functions to use our new component.
