Blockingdom

is a game

Technical info

Language: LuaJIT 5.1
Graphics library: Love2D
Game engine: a proprietary ECS heavily inspired by esper for Python (added chunk support)
World generation:
- Resource management: chunking N × N areas (currently 16 × 16)
- Cave generation: 2D simplex noise / 2D ridge noise
Lighting: iterative BFS every N frames. The lower the N, the smoother light updates feel, but the slower it is. An N > 1 is also harder to profile. The lightmap is then converted to an imageData object, which is then converted to a GPU texture. This texture is mapped onto the main window as a fragment shader, which also takes care of smoothing.
Color grading: color quantization in the fragment shader using shortest distance from a Nx1 pixel. This can be done after drawing the lighting (chiaroscuro) or after.
