+ + const tile = this.gridManager.getTileAtCoordinates(x, y); + if (tile) { + this.gridManager.selectTile(tile); + } +} +``` + +### Pattern 2: Selection State Management +**What:** Track selected tiles, enforce toggle rules, emit events at thresholds +**When to use:** Multi-step interactions where user selects items before action +**Example:** +```typescript +// In GridManager.ts +private selectedTiles: Tile[] = []; + +selectTile(tile: Tile): void { + if (tile.cleared) return; // Ignore empty tiles per CONTEXT.md + + const index = this.selectedTiles.findIndex(t => t.id === tile.id); + + if (index !== -1) { + // Toggle deselect: clicking selected tile deselects it + this.selectedTiles.splice(index, 1);

+ } +} +``` + +### Pattern 3: Fade-in Animation with GameLoop +**What:** Use delta time from existing GameLoop for smooth fade-in effects +**When to use:** Any UI animation that needs to run at 60fps without blocking +**Example:** +```typescript +// In Renderer.ts (or Tile model) +class TileRenderer { + private fadeStartTime: number | null = null;
