LibD2

Clean-room Diablo II 1.14d map generation for .NET. Give it a seed and it produces the same world the game does: rooms, preset objects and monsters, level adjacency and subtile collision, for every level of all five acts.

using LibD2.Drlg;

using var drlg = new MapGenerator();
var act = drlg.GenerateAct(seed: 1337, act: 0);   // 0 is Act I, 4 is Act V

foreach (var level in act.Levels)
    Console.WriteLine($"{level.Name}: {level.Rooms.Count} rooms at ({level.OriginX}, {level.OriginY})");
Rogue Encampment: 35 rooms at (1104, 1080)
Blood Moor: 83 rooms at (1064, 1120)
Cold Plains: 97 rooms at (984, 1080)
...

Generation is deterministic: the same seed always gives the same world, matching the retail engine cell for cell.

Collision

Grids are large, so they are only copied out when asked for:

var act = drlg.GenerateAct(1337, includeCollision: true);
var coldPlains = act.GetLevel(3)!;
var grid = coldPlains.Collision!;

if (grid.IsWalkable(x: 120, y: 200))
    Console.WriteLine("you can stand there");

Lifetime

MapGenerator holds the game tables and is IDisposable. Everything it returns is plain managed data with no native memory behind it, so an Act needs no disposing and is collected like any other object.

Not thread-safe. Give each thread its own MapGenerator.
