Offsets (offsets.ini)

All build-specific numbers live in two files, one per edition:

Xenvious/OfflineData/legacy/offsets.ini
Xenvious/OfflineData/enhanced/offsets.ini

The model hash lists (booster props, slowdown props, blacklisted props, ...) are in prop_lists.json next to them, also per edition. The struct offsets of the job image (0x1C) and the Social Club name (0x3CF) never moved and are constants in GTA.cs.

They are the sources of the build data, not files the app reads. tools/builddata/gen.py turns them (and scrpatches.json) into C# under Xenvious/Generated/, with every path already resolved to a number, so the start parses nothing. Run it after every change and commit what it writes; CI runs python -m unittest discover -s tools/builddata, which fails on stale files.

Sections

Section	Content
[BUILD]	label: the game build the values are for (1.73-3889, enhanced-1.73-1158); the updater migrates from it
[AOB]	Byte patterns (? = wildcard) for engine pointers: globals, script threads, script programs, camera, image, session, ...
[SCRIPTSPACE], [SCRIPTVICTIM]	Room for the custom funcs payload, see Script patches
[OFFSETS]	Globals, locals, struct fields and strides for everything the creator stores

Value formats

Example	Parsed by	Meaning
"Global_5242880.f_1[i /*170*/].f_3"	number	a global index, see Game memory
"fLocal_51531", "f_565"	number	a local index or a field offset
170, 0x1C, -0x24	number	plain number, decimal or hex, sign allowed
"8,DD0,30,50", AOB patterns, model lists	string	split at runtime where needed

Keys are case-insensitive and the first occurrence of a key wins; quotes and a trailing ;comment are dropped. Each key becomes a member named after it without OFFSET_ (OFFSET_actor_model -> d.OFFSETS.actor_model). A key only one edition has is 0 or "" in the other one, so guard against 0.

Where values end up

Helper Classes/OffsetLoader.cs (OffsetLoader.Load()) copies every value of BuildData.Current into static fields of GTA.Offsets.Editor in GTA.cs, grouped by what they describe (Props, DProps, Vehicle, Actor, Race.Checkpoints, Zones, Doors, ...). The rest of the code only uses those fields.

Adding an offset

1. Find the global or local in the decompiled creator script (see Updating for a new GTA build for where scripts come from).
2. Add the key to both legacy/offsets.ini and enhanced/offsets.ini, in decompiler notation. If you can only verify one edition, say so in the PR. Write the whole path: a field that is itself an array (one value per team, per rule) ends in [i], so its size slot is counted.
3. Run python3 tools/builddata/gen.py.
4. Add the static field to the matching class in GTA.cs and set it in OffsetLoader.Load(): GTA.Offsets.Editor.X = d.OFFSETS.my_key;.
5. Nothing else for the updater: ysc-global-updater migrates every key of these files at the next game update.
6. Use it through new Global(...), guarded against 0.
