# Phase 03 Plan 03: Forest Scene Summary
|
|
|
|
**SVG woodland background with 4x3 CSS grid overlay rendering IndexedDB forest elements with fade-in animation**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 2 min
|
|
- **Started:** 2026-03-29T11:40:00Z
|
|
- **Completed:** 2026-03-29T11:42:00Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 3
|
|
|
|
## Accomplishments
|
|
- SVG forest background with sky gradient, clouds, sun, background trees, hills, and ground
|
|
- 4x3 CSS grid overlay positioned absolutely over SVG for element placement
|
|
- renderForestScene() loads all ForestElements from IndexedDB and renders as images with random offset
|
|
- New element animation (fade-in + scale-up, 1.2s ease-out) via CSS class
|
|
- Object URL memory leak prevention with tracked revocation on re-render
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: SVG forest background and grid HTML structure** - `c9abc9e` (feat)
|
|
2. **Task 2: Render forest elements from IndexedDB** - `e1fc5eb` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `index.html` - Added forest scene container with SVG background and grid overlay in forest screen
|
|
- `src/styles/main.css` - Added forest scene CSS: grid layout, element styling, appear animation keyframes
|
|
- `src/forest/scene.ts` - Added renderForestScene() with IDB loading, Object URL management, animation class
|
|
|
|
## Decisions Made
|
|
- SVG element order: sky rect painted first (background), then clouds/sun, trees, hills, ground on top for correct visual layering
|
|
- Object URLs stored in module-level array and revoked before each re-render to prevent memory leaks
|
|
- Random offset of +-10-20px applied to each element image for natural, non-rigid placement within grid cells
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Forest scene ready for Plan 04 (reward flow) to call renderForestScene(db, newElementId) after generating new elements
|
|
- Level map still renders alongside the forest scene as expected
|
|
|
|
## Self-Check: PASSED
|
|
|
|
- All 3 modified files exist on disk
|
|
- Both task commits verified in git log (c9abc9e, e1fc5eb)
|
|
- SUMMARY.md created successfully
