conduit-prefab

conduit-prefab is the data-driven scene layer. A prefab is a JSON file under data/<namespace>/prefabs/<id>.json describing block volumes, anchors, zones, screens, labels, and sub-prefab references. The SceneStore loads prefabs at server start and on /reload; Scene.instantiate materialises one at any origin with any parameter bindings; Scene.remove rolls it back. Variable substitution (@xMin, @yFloor + 1) lets one prefab template parameterise across dozens of call sites.

When to depend on this

• You want game geometry defined in data files, not Java.
• You want /reload to re-instantiate edited prefabs without restarting the server.
• You want to mark named cuboid zones in a dimension and run callbacks on player entry.
• You’re spawning the same staging box / lobby room shape with different dimensions per call site.

Features

• Prefab loading + schema versioning
• Scene runtime
• Prefab bindings (variable substitution)
• Prefab geometry (volumes, IntVec3, IntExpr, orientation)
• Zones + zone manager
• Screen + label children inside prefabs
