Phase 3: UI Components Created

Summary

Created 3 React components for displaying TEI grades with full hysteresis support.

Components Created

1. TeiDisplay (tei-display.tsx + .module.scss)

Purpose: Primary rating display showing “V67” format with tooltips

Features:

• Shows grade letter + score (e.g., “V67”, “E84”)
• Colored by confidence (E=gold, V=blue, C=green, I=orange, P=gray)
• Hover tooltip shows:
  • Grade name and description
  • Conservative rating (score/99)
  • Raw OpenSkill (μ, σ)
  • Match count
  • Formula explanation
• Size variants: small, medium, large
• Optional objective label (“Go-Out Rating”, “Points Rating”)
• Hysteresis support: Accepts currentGrade prop

Props:

interface TeiDisplayProps {
  rating: PlayerRating;           // { mu, sigma, matches }
  currentGrade?: TeiGrade;         // For hysteresis (from Firestore)
  objective?: RatingTrack;         // 'goOut' | 'points'
  size?: 'small' | 'medium' | 'large';
  showTooltip?: boolean;           // Default: true
  showLabel?: boolean;             // Show objective label
  className?: string;
}

Usage:

<TeiDisplay 
  rating={playerStats.rating.goOut}
  currentGrade={playerStats.rating.goOut.displayGrade}
  objective="goOut"
  size="large"
  showLabel
/>

2. TeiChange (tei-change.tsx + .module.scss)

Purpose: Show rating changes after match completion

Features:

• Before → After display with arrow
• Delta display (+2, -3, etc.)
• Grade promotion/demotion badges
• Smooth animations (fade in, glow effect on promotions)
• Color-coded deltas (green +, red -, gray 0)
• Special celebration for grade upgrades (glow animation)
• Hysteresis support: Accepts before/after grades

Props:

interface TeiChangeProps {
  beforeRating: PlayerRating;
  beforeGrade?: TeiGrade;          // For hysteresis
  afterRating: PlayerRating;
  afterGrade?: TeiGrade;           // For hysteresis
  showDelta?: boolean;             // Default: true
  animate?: boolean;               // Default: true
  className?: string;
}

Usage:

<TeiChange
  beforeRating={beforeMatch}
  beforeGrade={storedGradeBefore}
  afterRating={afterMatch}
  afterGrade={storedGradeAfter}
  animate
/>

Animations:

• Before: 0.5s fade in
• Arrow: 0.3s slide in (0.5s delay)
• After: 0.5s fade in (0.8s delay)
• Promotion glow: 0.5s scale + brightness + drop-shadow (0.8s delay)
• Delta: 0.3s fade in (1.1s delay)
• Badge: 0.4s pop (1.2s delay)

3. TeiGradeBadge (tei-grade-badge.tsx + .module.scss)

Purpose: Compact grade indicator for tables/lists

Features:

• Just the letter (E/V/C/I/P) in colored circle
• Size variants: small (1.5rem), medium (2rem)
• Hover tooltip with grade name + description
• Hover effect: scale(1.1) + glow
• Accessible (aria-label)

Props:

interface TeiGradeBadgeProps {
  grade: TeiGrade;                 // 'E' | 'V' | 'C' | 'I' | 'P'
  size?: 'small' | 'medium';
  showTooltip?: boolean;           // Default: true
  className?: string;
}

Usage:

<TeiGradeBadge grade="V" size="small" />

Integration Checklist

Next Steps (Manual Integration Required):

1. Import Components:

   import { TeiDisplay, TeiChange, TeiGradeBadge } from './components';
   

2. Update Profile Page:
   • Replace old TEI display with <TeiDisplay />
   • Pass currentGrade from Firestore
   • Show both Go-Out and Points ratings side-by-side
3. Update Leaderboard:
   • Use <TeiGradeBadge /> in table rows
   • Use <TeiDisplay /> for detailed view
   • Sort by displayRating (μ - 3σ)
4. Update Match Summary:
   • Use <TeiChange /> to show before/after
   • Celebrate grade promotions with animation
5. Update In-Game HUD:
   • Use <TeiGradeBadge /> next to player names
   • Keep it minimal (just the badge)
6. Stats Service Integration:
   • Ensure displayGrade is read from Firestore
   • Pass it to all TEI components
   • Update Cloud Functions to write displayGrade on rating updates

Responsive Design

All components are mobile-friendly:

• TeiDisplay: Tooltip becomes modal on mobile (fixed position, centered)
• TeiChange: Wraps on small screens, reduces gap/font sizes
• TeiGradeBadge: Scales consistently, always circular

Breakpoint: max-width: 768px

Accessibility

✅ ARIA labels on all interactive elements
✅ Keyboard navigation support (hover states work with focus)
✅ Color contrast meets WCAG AA (text + color differentiation)
✅ Screen reader friendly (grade name + score announced)
✅ Reduced motion support (can disable animations via CSS prefers-reduced-motion)
