🎮 Game
A 2D tilemap library for s&box. It renders grid-based maps with chunked GPU instancing, generates colliders from tile data, and manages tilesets and painting/editing helpers. The code organizes a TileMap component, a TilemapRenderObject, a TileMapCollider, tileset resources, and some helper algorithms, plus an optional grass rendering example.
🔧 Editor
A 2D tilemap editor toolkit for s&box creators. It has tile brushes for manual, 2x2 edge, and 3x3 complex autotiling, plus editor widgets for layer management, tileset picking, rect ordering, per-tile data, and asset previews. The tools run inside the Editor, handle painting and stroke rasterization, and read or write TilesetResource assets.
🧪 Unit Test
Unit tests for the Tilemapper 2D library. It spins up Sandbox.TestAppSystem for the test run, creates a Scene, pushes it on the scene stack, spawns a GameObject, and asserts the scene directory sees one object.
