Combat UI Pattern A - Split-Panel Implementation

This skill guides implementation of the Split-Panel Combat UI, transforming the vertical theater mode into a horizontal confrontation layout.

Implementation Workflow

Step 1: Identify Target Component

Ask user which component to implement:

1. CombatLayout - Start here for new implementation
2. PhaseHeader - Top status bar
3. ConfrontationZone - Battle area with both panels
4. CharacterPanel - Individual character display
5. VSDivider - Center emblem and effects
6. ActionDock - Bottom skill bar
7. QuickActionCard - Compact skill card variant
8. MainActionCard - Large skill card variant

Step 2: Load Component Reference

Based on selection, load the appropriate reference:

• Layout/Structure: See layout-specs.md
• Component Props: See component-interfaces.md
• Styling Guide: See styling-tokens.md
• Animation Specs: See animations.md

Step 3: Generate Component Code

Follow the component template pattern:

import React from 'react';
import { cn } from '@/lib/utils'; // if using cn utility

interface ComponentNameProps {
  // Props from component-interfaces.md
}

export const ComponentName: React.FC<ComponentNameProps> = ({
  // destructured props
}) => {
  return (
    <div className={cn(
      // Base styles from styling-tokens.md
      // Conditional styles
    )}>
      {/* Component content */}
    </div>
  );
};

Step 4: Wire to Combat.tsx

After component creation:

1. Export from components/combat/index.ts
2. Import in Combat.tsx
3. Replace corresponding section
4. Pass required props from existing state

Quick Implementation Commands

Create All Files (Scaffolding)

# Create directory
mkdir -p src/components/combat

# Create all component files
touch src/components/combat/{index,CombatLayout,PhaseHeader,ConfrontationZone,CharacterPanel,VSDivider,ActionDock,QuickActionCard,MainActionCard}.tsx

Barrel Export Template

// src/components/combat/index.ts
export { CombatLayout } from './CombatLayout';
export { PhaseHeader } from './PhaseHeader';
export { ConfrontationZone } from './ConfrontationZone';
export { CharacterPanel } from './CharacterPanel';
export { VSDivider } from './VSDivider';
export { ActionDock } from './ActionDock';
export { QuickActionCard } from './QuickActionCard';
export { MainActionCard } from './MainActionCard';

Props Mapping from Existing Code

From App.tsx → Combat.tsx (unchanged)

player: Player
enemy: Enemy
turnState: 'PLAYER' | 'ENEMY_TURN'
turnPhase: TurnPhaseState
combatState: CombatState
onUseSkill: (skill: Skill) => void
onPassTurn: () => void
onToggleAutoCombat: () => void
autoCombatEnabled: boolean

Combat.tsx → New Components

// PhaseHeader
turnState, turnPhase, combatState.approach

// ConfrontationZone
player, enemy, playerStats, enemyStats

// CharacterPanel (player)
character: player, stats: playerStats, variant: 'player'

// CharacterPanel (enemy)
character: enemy, stats: enemyStats, variant: 'enemy'

// ActionDock
skills: player.skills, turnPhase, onUseSkill, onPassTurn

Migration Strategy

Phase 1: Layout Foundation

1. Create CombatLayout.tsx with CSS Grid
2. Create placeholder components
3. Add feature flag in Combat.tsx

Phase 2: Component Extraction

4. Implement CharacterPanel (extract from PlayerHUD + CinematicViewscreen)
5. Implement ActionDock (extract from skill grids)
6. Implement PhaseHeader (extract from inline indicators)

Phase 3: Visual Polish

7. Add VSDivider with effects
8. Implement animations
9. Adjust floating text positions

Phase 4: Cleanup

10. Remove old theater mode code
11. Remove feature flag
12. Update tests

Reference Files

• layout-specs.md - CSS Grid structure, responsive breakpoints
• component-interfaces.md - TypeScript interfaces for all components
• styling-tokens.md - Colors, spacing, typography tokens
• animations.md - Animation keyframes and transitions

Output Format

Generate TypeScript React components with:

1. TypeScript interface for props
2. Tailwind CSS for styling (matching existing codebase)
3. Responsive classes (mobile fallback to vertical)
4. Memoization where appropriate (React.memo for cards)
5. Accessibility attributes (aria-labels, roles)
