UT2004 DM Map Project

Reading, interpreting, and reconstructing official UT2004 Deathmatch maps — with the longer-term goal of programmatically generating/modifying them. Scope is the 39 stock DM maps shipped with the game (binary .ut2 Unreal packages).

Project report (GitHub Pages): https://ianfinkdata.github.io/claude_ut2k4/

Architecture

Read binary, write via T3D. Hand-authoring binary .ut2 files is too fragile — instead:

1. Read — parse the binary .ut2 directly in Python (ut2parser.py).
2. Write — generate/modify T3D (UnrealEd’s plain-text export format).
3. Finalize — import the T3D into UnrealEd, Build Geometry → Build Lighting → save .ut2.

Repo map

• Maps/ — 39 stock UT2004 DM maps (.ut2, binary Unreal packages).
• ut2parser.py — binary reader, property decoder, JSON model, diff, T3D generator.
• schema_extractor.py / schema.json — class schema (enums/arrays) extracted from the game’s UnrealScript.
• navanalysis.py / NAV_PATTERNS.md — bot-pathing & inventory pattern analysis across all maps.
• import_kit/ — UnrealEd import kit (clean T3D subsets + paste instructions).
• replica/ — a fully replicated, engine-verified map (DM-Rankin-Replica.ut2).
• docs/ — source for the GitHub Pages report.
• CLAUDE.md — durable project context & file-format notes.
• PROGRESS.md — status, findings, and roadmap.

Quick start

python ut2parser.py Maps/DM-Rankin.ut2              # summarize one map
python ut2parser.py Maps/DM-Gael.ut2 --actors       # placed actors w/ location+rotation
python ut2parser.py Maps/DM-Rankin.ut2 --t3d > out.t3d   # generate full-map T3D

python navanalysis.py Maps/*.ut2                    # bot-path/inventory report

See PROGRESS.md for full details and CLAUDE.md for format notes.
