## Recent Changes
|
||
|
||
### Intent-Based Architecture
|
||
- **Completed major refactor** (3 weeks ago): Systems now communicate through one-frame `Storage<T>` intents instead of direct function calls.
|
||
- **Intent types**: `FollowPlayerIntent`, `StopFollowingIntent`, `CameraTransitionIntent`, `SpawnParticleIntent`
|
||
- **Consumer pattern**: Systems read intents from world storage, act on them, then remove them. Producers don't import consumer modules.
|
||
- **Documented pattern** in `docs/intent-based-architecture.md` with full execution order contract.
|
||
|
||
### Dialog System Suite
|
||
- **Dialog state machine**: Ink-based story progression with display timer, projectile phases, parry mechanics.
|
||
- **Projectile system**: Spawns physics-driven projectiles with parry windows; detects hits vs. evasion vs. parries (I/J/L buttons).
|
||
- **Dialog camera**: Auto-frames all dialog participants; transitions smoothly between follow-cam and dialog-cam via intent; computes centroid + spread.
|
||
- **Bubble rendering**: Billboard-based text with word-wrap, dynamic sizing (tail height → body dimensions), border/fill colors, RGBA text atlas.
|
||
|
||
### Text & Font Rendering
|
||
- **Font atlas pipeline**: Pre-rasterized glyphs (16×8 grid, 124px cells) from Departure Mono font.
|
||
- **Text measurement**: Character-width aware layout with line wrapping against max bubble width.
|
||
- **Vertex-based text**: Custom `TextVertex` (position, UV) fed into dedicated text pipeline with view-proj uniform.
|
||
|
||
### Particle System
|
||
- **Intent-driven spawning**: `SpawnParticleIntent` queues particle emissions; `particle_intent_system` transfers into persistent `ParticleBuffers`.
|
||
- **Configurable emitters**: Burst count, lifetime range, speed range, directional spread (cone), gravity, size range, color gradient.
|
||
- **Snow particle integration**: Spawned continuously at camera position for screen-fill effect.
|
||
|
||
### Render Pipeline
|
||
- **Global renderer via thread-local**: `render::global` module centralizes `Device`/`Queue` access for loaders and systems; long-term goal is explicit `RenderContext` params.
|
||
- **Gizmo shader**: Fragment shader outputs world-normal as axis color (X=red, Y=green, Z=blue) for entity transform editing.
|
||
- **Snow light accumulation**: Persistent texture tracking deformation; blue-noise dithering maps snow brightness into tile pattern (brightness > threshold → dither step).
|
||
- **Dissolve shader**: Blue-noise masked alpha cutoff; controlled by `enable_dissolve` uniform.
|
||
|
||
### Tree Occlusion & Instances
|
||
- **Tree dissolve system**: Per-instance dissolve amounts lerp toward targets at configurable speed.
|
||
- **Occlusion detection**: Instances between camera and player dissolve based on perpendicular distance to camera-to-player ray.
|
||
- **Instance buffer sync**: Tree instances updated into GPU buffer after dissolve state changes.
|
||
|
||
### Trigger & Event Flow
|
||
- **Sphere-based triggers**: Continuous state tracking (Idle ↔ Inside); fires `TriggerEvent` with `Entered`/`Exited` kinds.
|
||
- **Activation filtering**: `TriggerFilter::Player` specifies which entity types can activate.
|
||
- **Event queue**: Events collected in `world.trigger_events` and consumed by dialog system to spawn bubbles.
|
||
|
||
### Player State Machine
|
||
- **State hierarchy**: Idle, Walking, Jumping, Falling, Leaping (dash), Rolling.
|
||
- **Transition logic**: Grounded checks, input presence, airtime duration.
|
||
- **Physics per-state**: Damping on enter (Idle), horizontal input application (Walking), vertical velocity control (Jumping).
|
||
|
||
### Editor & Inspector
|
||
- **Dear ImGui integration**: Inspector window with player state display, entity transform gizmos.
|
||
- **Entity selection**: Right-click picking; gizmo renders for selected entity when editor active.
|
||
- **UI mode gating**: Systems check `editor.wants_keyboard()`/`wants_mouse()` to suppress game input during inspector focus.

|
||
## Open Threads
|
||
|
||
- **Global renderer thread-local**: Marked for gradual migration to explicit `RenderContext` parameters on systems/loaders. Current implementation works; refactor is low-priority.
|
||
- **Text rendering completeness**: Font atlas + text pipeline in place; scaling and color support functional. No known issues.
|
||
- **Dialog parry mechanics**: Projectile system complete; integration with Ink outcomes working. Gameplay tuning (PARRY_WINDOW_RADIUS, HIT_RADIUS) ongoing.
|
||
- **Tree occlusion performance**: Occlusion system runs every frame; no visibility culling yet. Scalability unknown for >100 trees. |
