## Implementação Técnica
### Persistência de Dados
Todos os dados de gamificação são salvos automaticamente no localStorage:
```typescript
// Chave: 'piano-tutor-gamification'
{
streak: number;
bestStreak: number;
todayPracticed: boolean;
achievements: Achievement[];
totalPoints: number;
level: number;
leaderboard: LeaderboardEntry[];
}
// Chave: 'last-practice-date'
// Valor: string (toDateString)
```
### Sistema de Streaks
O sistema de streaks funciona com verificação de datas:
```typescript
// Lógica de atualização
const today = new Date().toDateString();
const lastPractice = localStorage.getItem('last-practice-date');
if (lastPractice === yesterday) {
streak += 1; // Prática consecutiva
} else if (lastPractice !== today) {
streak = 1; // Nova sequência
}
```
### Sistema de Pontos e Níveis
```typescript
// Pontos ganhos por conquista
points = achievement.points;
// Cálculo de nível
level = Math.floor(totalPoints / 100) + 1;
// Progresso para próximo nível
progress = (totalPoints % 100) / 100;
```
### Web Audio API (Metrônomo)
```typescript
const audioContext = new AudioContext();
const oscillator = audioContext.createOscillator();
const gainNode = audioContext.createGain();
oscillator.frequency.value = isAccented ? 1000 : 800;
oscillator.type = 'sine';
gainNode.gain.setValueAtTime(0.3, audioContext.currentTime);
gainNode.gain.exponentialRampToValueAtTime(
0.01,
audioContext.currentTime + duration
);
oscillator.start(audioContext.currentTime);
oscillator.stop(audioContext.currentTime + duration);
```
## Animações CSS
### Pulse Animation
```css
@keyframes pulse {
0%, 100% { transform: scale(1); }
50% { transform: scale(1.1); }
}
```
### Inferno Animation
```css
@keyframes inferno {
0% { transform: scale(1) rotate(0deg); }
50% { transform: scale(1.2) rotate(5deg); }
100% { transform: scale(1.1) rotate(-5deg); }
}
```
## Responsividade
Todos os componentes são totalmente responsivos com breakpoints:
- **Desktop**: Grid completo com todas as colunas
- **Tablet** (< 1024px): Layout em coluna única
- **Mobile** (< 768px): Elementos empilhados, controles simplificados
## Integração com Backend
### Endpoints Sugeridos
```typescript
// Salvar progresso
POST /api/v1/gamification/progress
Body: {
userId: string;
streak: number;
totalPoints: number;
level: number;
}
// Carregar leaderboard
GET /api/v1/gamification/leaderboard?timeFrame=weekly
// Registrar sessão
POST /api/v1/sessions
Body: {
userId: string;
duration: number;
accuracy: number;
achievements: string[];
}
// Desbloquear conquista
POST /api/v1/achievements/unlock
Body: {
userId: string;
achievementId: string;
}
```
## Exemplos de Uso Completo
### Registrar Sessão de Prática
```typescript
const StudentDashboard = () => {
const gamification = useGamification();
const handleSessionComplete = () => {
const sessionData = {
duration: 30, // 30 minutos
accuracy: 0.95, // 95% de precisão
hasErrors: false // Sem erros
};
// Registrar sessão
gamification.recordSession(sessionData);
// Verificar conquistas desbloqueadas
// - first_session
// - accuracy_master (95%)
// - marathon (30 min)
// - perfect_session (sem erros)
};
return (
<button onClick={handleSessionComplete}>
Concluir Sessão
</button>
);
};
```
### Configurar Loop de Estudo
```typescript
const PracticeSession = () => {
const [loopConfig, setLoopConfig] = useState({
measures: [5, 6, 7, 8],
isActive: false
});
const handleLoopChange = (measures, isLooping) => {
setLoopConfig({ measures, isActive: isLooping });
if (isLooping) {
// Iniciar player de partitura com os compassos selecionados
startScorePlayer(measures);
}
};
return (
<StudyLoop
measures={Array.from({ length: 32 }, (_, i) => i + 1)}
onLoopChange={handleLoopChange}
currentMeasure={currentMeasure}
/>
);
};
```

- ✅ Navegação por Tab
## Testes
### Testes Sugeridos
```typescript
describe('useGamification', () => {
it('deve atualizar streak corretamente', () => {
const { result } = renderHook(() => useGamification());
act(() => {
result.current.updateStreak();
});
expect(result.current.streak).toBeGreaterThan(0);
});
it('deve desbloquear conquista', () => {
const { result } = renderHook(() => useGamification());
act(() => {
result.current.unlockAchievement('first_session');
});
const achievement = result.current.achievements.find(
a => a.id === 'first_session'
);
expect(achievement?.unlocked).toBe(true);
});
});
describe('Metronome', () => {
it('deve iniciar e parar corretamente', () => {
const { getByText } = render(<Metronome />);
const startButton = getByText('▶️ Iniciar');
fireEvent.click(startButton);
expect(getByText('⏹️ Parar')).toBeInTheDocument();
});
});
```
## Troubleshooting
### Problema: Metrônomo não toca
**Solução**: Verificar se o navegador suporta Web Audio API e se há permissão de áudio.
### Problema: Streak não atualiza
**Solução**: Limpar localStorage e verificar timezone do dispositivo.
### Problema: Conquistas não desbloqueiam
**Solução**: Verificar se o progresso está sendo atualizado corretamente e se as condições foram satisfeitas.
## Conclusão
A Feature 7 fornece uma experiência completa e engajadora para os alunos, combinando:
- ✅ **Gamificação** para manter motivação
- ✅ **Ferramentas práticas** para estudo eficiente
- ✅ **Dashboard intuitivo** com métricas claras
- ✅ **Persistência local** para experiência contínua
- ✅ **Design responsivo** para todos os dispositivos
- ✅ **Performance otimizada** para interação suave
