PassthroughIn development
SubCraft
Play Subnautica as a Minecraft player. A hidden Minecraft owns the player; Subnautica owns the world and draws every pixel, including Minecraft's blocks and mobs.
Early development. The link, Minecraft-driven movement and the look spike (Minecraft blocks drawn by Subnautica's own shader) are done; exact collision is in progress. See the repo's DEVLOG for progress.
README
On GitHubSubCraft
Play Subnautica as a Minecraft player: one world, one light, one sound, one physics.
A hidden Minecraft (1.21.1, NeoForge) runs beside Subnautica. The two talk through one shared memory file with a fixed binary protocol. Minecraft owns the player: physics, inventory, combat math, blocks and Minecraft mobs. Subnautica owns the world: terrain, creatures, light, sound and saves, and it draws every pixel of the 3D scene, including Minecraft's blocks and mobs, which it captures as geometry and lights like its own.
Status: early development. Done: the link (0a), Subnautica driven by Minecraft's physics (0b), the look spike (0c: Minecraft blocks drawn by Subnautica's own shader). In progress: Phase 1, starting with exact collision (Minecraft's player collides with Subnautica's real collision surface). See MISSION.md for the plan, docs/DEVLOG.md for progress and docs/TESTING.md for what to try.
