- Load atlas texture at app startup via HtmlImageElement onload callback - Rewrite platformer_render.rs: all objects now use MeshType::Quad + MaterialType::Sprite instead of 3D Cuboid/Sphere meshes - Animated sprite selection per AnimState (player) and EnemyType - HP hearts rendered as sprite quads above each player - Per-tile sprite mapping, power-up sprite mapping, projectile sprites - Fix bridge.rs PlayerId type (u64, not u32) for WASM build Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The quad was facing -Z but the camera is at Z=-15 looking toward Z=0 (+Z direction). This caused the sprite UVs to be mirrored horizontally, making the game appear right-to-left. Fix by winding the quad CCW when viewed from +Z so the front face is toward the camera. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Camera was at Z=-15 looking toward Z=0 (+Z direction), which in look_at_rh flips the X axis on screen, causing the entire game to render right-to-left with swapped controls. Moved camera to Z=+15 so it looks along -Z where +X = right on screen. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Complete 10-phase graphics upgrade for the platformer: - 512x512 sprite atlas with 129 named sprites and animation tables - 3-layer parallax scrolling backgrounds with custom GLSL shaders - Multi-frame SpriteAnimation for all player/enemy/tile animations - Auto-tiling for stone bricks (neighbor-based edge detection) - Animated torches, checkpoints, finish gates - Particle system (256-cap ring buffer): dust, sparks, blood, fire, smoke, magic effects with per-type colored powerup bursts - Screen shake on damage/death, screen flash on hits/kills - Attack trail afterimages, speed boots green trail, invincibility glow - Death fade-out and respawn fade-in transitions - Tile culling (only render visible columns around camera) - Enemy death animations with fade-out Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…her, post-FX, particles, HUD Complete 10-phase visual upgrade for the platformer game mode: - Water shader with waves, caustics, and gameplay (movement slow + buoyancy) - Dynamic torch lighting (16-light array, flicker, dark atmosphere) - Whip arc shader and projectile trail effects with impact sparks - Squash/stretch animation (1024x512 atlas, per-player visual state) - Weather system (rain, fog) and foreground parallax layer - CRT + bloom + vignette post-processing via render-to-FBO pipeline - Enhanced particle system (512 cap, 6 new effects, continuous emission) - HUD: powerup timer bar, course minimap canvas, checkpoint toast - Theme-configurable torch ambient, water color, and post-FX intensities - Context loss resilience for post-process FBO Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace the flat 300×30 horizontal strip with a 192×120 tile castle labyrinth (6×5 grid of 32×24 rooms, ~22 rooms per map). Rooms are connected via MST + extra edges for multiple routes, themed by distance from start (Entrance → Corridor → GreatHall/Library → Armory/Chapel/Crypt → Tower/Dungeon → ThroneRoom). Includes RLE tile compression, 2D checkpoint system, room-distance rubber-banding, camera/culling for vertical exploration, room-graph minimap, and sprite V-flip fix.

…ting, parallax, post-FX, weather, HUD Phases 5-10 of the anime dark fantasy visual polish: - Phase 5: Slash arc + magic circle shaders, hit freeze on enemy kills - Phase 6: Multi-layer water with caustics, foam, depth absorption, Fresnel - Phase 7: 32 colored lights, per-room ambient color, god rays shader - Phase 8: 6-layer parallax with sway and crossfade support - Phase 9: Multi-pass post-processing: bloom, color grading, chromatic aberration, film grain - Phase 10: Weather system (rain/lightning/fog/ambient particles per room), procedural health bar, room name reveal toast New shaders: slash_arc, magic_circle, godrays, fog_layer, health_bar (10 files). Expanded sprite.frag to 32 colored lights, rewrote water.frag and postprocess.frag. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Fix atlas dimensions (2048x1024→1024x512, 32x64→16x32 sprites) to match actual PNG on disk, fixing garbled/invisible sprites. Fix depth_mask leak from parallax rendering that silently disabled depth writes for all subsequent sprites. Add MBAACC (Melty Blood) visual techniques: - Binary alpha (step 0.5) for crisp pixel outlines - Dark pixel outlines on characters/enemies via existing shader - Explicit Z-layer painter's algorithm (8 depth layers) - Character shadows (squashed dark silhouettes) - BlendMode enum (Normal/Additive/Subtractive) on sprites - Palette texture infrastructure (deferred activation) - Per-material GL state restoration after every draw call Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Restyle the platformer to match GBA-era Castlevania (Circle of the Moon, Curse of Darkness) with dark ambient, high-contrast torch lighting, and authentic color processing. Color tuning across all rooms: darker ambient (~33% reduction), distinctly orange torch fire, higher contrast/lower saturation color grading, per-room tile tints (gray-mauve castle, teal-green underground, warm sandstone sacred, blue-gray fortress), darker parallax with purple tint, more atmospheric fog and dust particles. Shader authenticity: GBA 5-bit posterization (floor * 31.0), 3-point color ramp mapping (mauve shadows -> bronze midtones -> gold highlights blended 70% with original texture), dark plum pixel outlines matching Castlevania sprite style. Theme defaults: torch_ambient 0.06, bloom 0.55, vignette 0.7, scanline 0.15. VFX recolored: orange-gold slash arcs, ghostly green projectiles, orange fire speed trails. Graduated film grain for dark rooms. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add visual-audit.spec.js Playwright test that captures 6 platformer screenshots with color histograms for automated visual analysis. Brighten the Castlevania GBA/DS restyle based on Gemini feedback: - torch_ambient 0.06→1.0, radius 6.5→14.0, intensity 1.2→1.8 - Room ambient colors raised to 0.45-0.90 range (was 0.05-0.20) - Tile tints boosted above 1.0 for sprite overdrive brightness - Color ramp shadow/mid lifted, posterize 31→16 for authentic GBA banding - Contrast neutralized (1.0), saturation raised to 1.05 (GBA LCD compensation) - Shadow grade tints lightened to 0.78-0.92 to preserve dark detail - Vignette 0.7→0.20, scanlines 0.15→0.05, CRT curvature 0.12→0.08 - Parallax alpha reduced for better tile/background contrast - Shader min light floor: max(light, u_ambient*0.4) - Fog color brightened to [0.12, 0.10, 0.18] Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fix player/enemy/VFX sprite atlas↔Rust frame count mismatches (phases 1-2) - Fix parallax background atlas reference and per-room tinting (phase 3) - Tune visual defaults: torch_ambient 0.15, posterize 48, ramp blend 0.35 (phase 4) - Increase scene capacity to 2048 and reset object IDs each frame (phase 5) - Add dynamic vertex batching with sprite_batch shaders for ~100x fewer draw calls (phase 6) - Add TileCache for O(1) static tile lookups instead of per-frame HashMap (phase 7) - Add camera sub-pixel snapping at 1/16 pixel grid for crisp pixel art (phase 8) - Reduce weather particle counts and widen rain sprites (phase 9) - Add per-room fog color propagation through shaders (phase 10) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Rename u_vp to u_mvp in sprite_batch.vert so the Rust uniform lookup actually finds it — tiles were invisible because the VP matrix was never uploaded to the batch shader - Disable parallax background layers that sampled character/tile sprites from the atlas instead of dedicated background content Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
