JGengine world runtime

Ownership

This skill owns runtime spatial behavior: authored-scene consumption, environments, movement, input mapping, interaction, AI, navigation, physics, visibility, time, and spatial audio. Scene creation and placement stay in jgengine-editor; presentation stays in jgengine-ui.

Search capabilities.md by intent before designing a primitive. Use api.md for exact exports and reference.md for environment, camera, navigation, physics, audio, and authored-scene recipes.

Canonical workflows

Authored world

1. Load the scene document through the shared authored-scene feature.
2. Render objects, paths, terrain, foliage, and markers generically.
3. Query the same ids/layers for spawns, routes, plots, and interaction.
4. Keep derived caches rebuildable; the document remains authoritative.
