Axel Meyer 3457a7eab8 feat: sprite-mode test-chamber with 13-bone puppet + sprite-tilemap
13-bone humanoid rig (12 visible bones + 1 root) hand-ported from
substrate reference, mapped to PROTOTYPE asset-pack via asset_aliases
indirection (asset_pack: player). Bones use texture/z_order/scale/
anchor fields from the rig-format extension. Tracks split: lower for
legs + feet (walk animation), upper for root/body/head/shoulders/arms
(idle animation).

Animations:
- idle.anim.json: 2.0s loop on upper track, subtle body+head sway
- walk.anim.json: 0.6s loop on lower track, legs+feet cycle

Sprite-tilemap: 4-tile palette (floor_001-003 walkable, floor_004
as wall). Map content: 20x20 with wall-border and interior wall
blocks. tile_rotations parallel array exercises 90 and 180-degree
rotations on a handful of cells for visual rotation-pipeline
verification.

init.lua loads textures via asset_aliases lookup:
- maps.load_textures(aliases) resolves tilemap-tile atlas-ids
- puppet.load_rig(path, aliases) loads + resolves bone textures
- furniture textures preloaded at init (bed, bench, backpack) to
  avoid first-frame load stutter; rendered via engine.render.
  draw_sprite_transform in the draw hook

Camera follows puppet via per-frame camera.set_target. Headtrack:
head bone (look_at: true) rotates to face mouse world-position.

New SPOREL_CI=1 traces from render and init hooks:
- vagrant: render_frame_ok (per frame from render)
- vagrant: sprite_mode=on (once after first sprite-draw)
- vagrant: assets_loaded=14 (once after init: 7 puppet + 4 tile + 3 furniture)

sporel-module-vagrant-skeleton

F.vagrant Tier-1 test-chamber: single player as puppet, WASD direct movement, camera-chase, headtrack to mouse-cursor. Phase 1 stage.

Version: 0.2.0 Module-ID: vagrant-skeleton Requires: lib-core.input >=0.4.0, lib-core.camera >=0.3.0, lib-core.render >=0.1.0, lib-core.maps >=0.1.2, lib-core.puppet >=0.2.0, lib-asset.prototype-subterrain >=0.1.0 Tags: test-chamber, puppet, walking-sim

Topology

Controls

  • W A S D — direct movement (4-way, normalized for diagonals)
  • Mouse — head/torso look-at target
  • ESC — return to launcher

Demonstrates

  • lib-core.puppet integration (skeleton, keyframe animation, procedural-ready, look-at constraint)
  • idle <-> walk animation-state transition driven by movement input
  • Camera-chase via lib-core.camera target-provider
  • Throwaway-content test-chamber stance: existing maps v0.1 format, hand-painted humanoid rig + 2 keyframe animations.

Interactions

  • WASD active -> walk animation on lower track
  • WASD released -> idle animation on upper track (subtle torso sway)
  • Mouse moved -> head-bone angle updates each frame to face cursor's world-position (look-at constraint on bones marked look_at: true)

CI Hooks

  • SPOREL_CI=1 -> 60-frame perf canary. Emits vagrant: frame_avg_ms=N and vagrant: render_frame_ok (per-frame, from render hook), then exits. Used by smoke stages P0-S25a + P0-S25b.

CHANGELOG

v0.2.0

  • Sprite-mode rendering throughout: 13-bone humanoid puppet via lib-core.puppet v0.2 with PROTOTYPE asset-pack textures; sprite-tilemap via lib-core.maps v0.1.2 with 4 floor variants (floor_001-003 walkable, floor_004 as wall); hardcoded furniture (bed, bench, backpack) via engine.render.draw_sprite_transform.
  • Asset-pack indirection: manifest.module asset_aliases maps the alias- keys (player, tiles, world) to lib-asset.prototype-subterrain. Rig and tilemap atlas-ids resolved at init via puppet.load_textures and maps.load_textures.
  • Tile rotations: vagrant_test.map.json includes a tile_rotations parallel array exercising 90 and 180-degree rotations for visual verification of the rotation pipeline.
  • Animation refinements: walk on lower track now includes foot bones (legs + feet alternate); idle on upper track with subtle body+head sway.
  • New smoke traces emitted under SPOREL_CI=1: vagrant: render_frame_ok (per frame from render hook), vagrant: sprite_mode=on (once after first sprite draw), vagrant: assets_loaded=14 (once after init).
