Revision as of 21:02, 30 August 2012

Current version of town description format.

Remaining tasks

• Remove usage of numeric ID's. Long-term goal due to heavy usage of id's in VCMI code.
• Determine location of name and descriptions (buildings or structures)
• Collect any remaining hardcoded data

Split faction description from town description

Currently there is no separation between "faction" and "town" concepts. This results in several issues:

• Neutral creatures have invalid faction - no town with such description is present
• Loading towns requires creatures and loading creatures requires towns

This should be split into several parts:

• faction: stores all information that can be separated from town (e.g. puzzle map, hero classes, creatures)
• town: stores only information required for town (e.g. buildings and recruitable creatures)
• (optional) town gui: separate structure will all gui-specific data (e.g. structures)

Merge in remaining json configs

• (DONE) buildings.json (used as base for this configuration)
• (DONE) creatures_backgrounds.json
• (DONE) hall.json
• (DONE) town_pictures.json
• (DONE) towns_defs.json
• (DONE) wall_pos.json (needs removing hardcoded name)
• puzzle_map.json (needs removing hardcoded name)

Won't be used:

• commanders.json (leave it as it?)
• terrains.json (movement speed should be left in terrain configuration I think)

Merge in data from HoMM3 txt files

• (DONE) BldgNeut.txt
• (DONE) BldgSpec.txt
• (DONE) Dwelling.txt
• (DONE) Building.txt
• (DONE) TownName.txt
• (DONE) TownType.txt
