wow-wdt

A library for parsing, validating, and converting World of Warcraft WDT (World Data Table) files.

Status

Production Ready - Complete WDT parser with 100% parsing success rate across all WoW versions

Version Support

Features

• Parse WDT files from all WoW versions (Classic through MoP)
• Validate WDT structure with validation rules
• Create new WDT files programmatically
• Convert WDT files between different WoW versions
• Support for all chunk types (MVER, MPHD, MAIN, MAID, MWMO, MODF)
• Coordinate system conversion utilities
• 100% parsing success rate
• Tested with real WoW data files

Quick Start

Add to your Cargo.toml:

[dependencies]
wow-wdt = "0.6"

Or use cargo add:

cargo add wow-wdt

Basic Usage

use std::fs::File;
use std::io::BufReader;
use wow_wdt::{WdtReader, version::WowVersion};

// Parse a WDT file
let file = File::open("path/to/map.wdt")?;
let mut reader = WdtReader::new(BufReader::new(file), WowVersion::WotLK);
let wdt = reader.read()?;

// Get basic information
println!("Map type: {}", if wdt.is_wmo_only() { "WMO-only" } else { "Terrain" });
println!("Existing tiles: {}", wdt.count_existing_tiles());

// Check specific tile
if let Some(tile) = wdt.get_tile(32, 32) {
    println!("Center tile has ADT: {}", tile.has_adt);
    println!("Area ID: {}", tile.area_id);
}

Creating WDT Files

use wow_wdt::{WdtFile, WdtWriter, version::WowVersion, chunks::MphdFlags};
use std::fs::File;
use std::io::BufWriter;

// Create a new terrain map
let mut wdt = WdtFile::new(WowVersion::WotLK);

// Configure as terrain map with height texturing
wdt.mphd.flags |= MphdFlags::ADT_HAS_HEIGHT_TEXTURING;

// Mark some tiles as having ADT data
wdt.main.get_mut(31, 31).unwrap().set_has_adt(true);
wdt.main.get_mut(31, 32).unwrap().set_has_adt(true);
wdt.main.get_mut(32, 31).unwrap().set_has_adt(true);
wdt.main.get_mut(32, 32).unwrap().set_has_adt(true);

// Write to file
let file = File::create("new_map.wdt")?;
let mut writer = WdtWriter::new(BufWriter::new(file));
writer.write(&wdt)?;

Version Conversion

use wow_wdt::conversion::{convert_wdt, get_conversion_summary};

// Convert from WotLK to Cataclysm format
let changes = get_conversion_summary(
    WowVersion::WotLK,
    WowVersion::Cataclysm,
    wdt.is_wmo_only()
);

for change in changes {
    println!("Change: {}", change);
}

convert_wdt(&mut wdt, WowVersion::WotLK, WowVersion::Cataclysm)?;

Coordinate Conversion

use wow_wdt::{tile_to_world, world_to_tile};

// Convert tile coordinates to world coordinates
let (world_x, world_y) = tile_to_world(32, 32);
println!("Tile [32, 32] is at world position ({:.2}, {:.2})", world_x, world_y);

// Convert world coordinates back to tile coordinates
let (tile_x, tile_y) = world_to_tile(world_x, world_y);
println!("World position maps to tile [{}, {}]", tile_x, tile_y);

CLI Tool

WDT operations are available through the main warcraft-rs CLI tool:

# Get information about a WDT file
warcraft-rs wdt info Azeroth.wdt

# Validate WDT structure
warcraft-rs wdt validate Azeroth.wdt

# List all existing tiles
warcraft-rs wdt tiles Azeroth.wdt --format json

# Convert between versions
warcraft-rs wdt convert input.wdt output.wdt --to wotlk

# Visualize WDT structure as a tree
warcraft-rs wdt tree Azeroth.wdt --show-refs

File Format Details

WDT files define which terrain tiles exist for a map and contain:

• MVER: Version chunk (always 18)
• MPHD: Map header with flags and FileDataIDs
• MAIN: 64x64 grid of tile information
• MAID: FileDataID mapping (BfA+ only)
• MWMO: WMO filename storage (WMO-only maps or pre-Cata terrain)
• MODF: WMO placement data (WMO-only maps)

Testing

Basic tests are included:

# Run all tests
cargo test

# Benchmarks are planned but not yet implemented
