Method 3: Advanced Configuration with Time-Based Messages¶

// live2d-enhanced.js
function getTimeBasedMessage() {
    const hour = new Date().getHours();
    if (hour < 6) return "So late... you should get some rest.";
    if (hour < 9) return "Good morning! Have a great day!";
    if (hour < 12) return "Good morning! The weather looks nice today.";

    if (hour < 22) return "Good evening! How was your day?";
    return "Good evening! Don't stay up too late!";
}

function initializeEnhancedLive2D() {
    if (typeof L2Dwidget !== 'undefined') {
        L2Dwidget.init({
            "model": {
                "jsonPath": "https://unpkg.com/live2d-widget-model-shizuku@1.0.5/assets/shizuku.model.json",
                "scale": 1
            },
            "display": {
                "position": "right",
                "width": 180,
                "height": 220,
                "hOffset": 0,
                "vOffset": -20
            },
            "mobile": {
                "show": false,
                "scale": 0.8
            },
            "react": {
                "opacity": 0.85
            }
        });

        // Add click event for time-based messages
        setTimeout(() => {
            const canvas = document.getElementById('live2dcanvas');
            if (canvas) {
                canvas.addEventListener('click', function() {
                    showMessage(getTimeBasedMessage());
                });
            }
        }, 2000);
    }
}

function showMessage(message) {
    // Create temporary message display
    const msgDiv = document.createElement('div');
    msgDiv.style.cssText = `
        position: fixed;
        bottom: 100px;
        right: 20px;
        background: rgba(0,0,0,0.8);
        color: white;
        padding: 10px 15px;
        border-radius: 10px;
        font-size: 14px;
        max-width: 200px;
        z-index: 9999;
        animation: fadeInOut 3s ease-in-out;
    `;
    msgDiv.textContent = message;

    // Add CSS animation
    if (!document.getElementById('live2d-msg-style')) {
        const style = document.createElement('style');
        style.id = 'live2d-msg-style';
        style.textContent = `
            @keyframes fadeInOut {
                0% { opacity: 0; transform: translateY(10px); }
                20%, 80% { opacity: 1; transform: translateY(0); }
                100% { opacity: 0; transform: translateY(-10px); }
            }
        `;
        document.head.appendChild(style);
    }

    document.body.appendChild(msgDiv);

    setTimeout(() => {
        if (msgDiv.parentNode) {
            msgDiv.parentNode.removeChild(msgDiv);
        }
    }, 3000);
}

// Initialize when DOM is ready
if (document.readyState === 'loading') {
    document.addEventListener('DOMContentLoaded', function() {
        setTimeout(initializeEnhancedLive2D, 1500);
    });
} else {
    setTimeout(initializeEnhancedLive2D, 1500);
}

🎨 Character Selection and Customization¶

Available Character Types¶

Anime-style Characters
shizuku - Blue-haired girl
miku - Popular virtual singer
hibiki - Energetic character
Cat Characters
tororo - White cat
koharu - Seasonal cat character
Original Characters
Custom models can be loaded via URL

Position and Size Customization¶

"display": {
    "position": "left",        // left, right
    "width": 150,             // Character width
    "height": 200,            // Character height
    "hOffset": 0,             // Horizontal offset
    "vOffset": -20            // Vertical offset
}

📱 Mobile and Responsive Support¶

Mobile Display Control¶

"mobile": {
    "show": false,            // Hide on mobile
    "scale": 0.8             // Scale for mobile if shown
}

Screen Size Detection¶

function isMobile() {
    return window.innerWidth <= 768;
}

function initializeLive2DResponsive() {
    if (isMobile()) {
        // Mobile-specific settings
        return;
    }
    // Desktop implementation
    initializeLive2D();
}

🛡️ Performance and Security Considerations¶

Loading Optimization¶

// Lazy loading implementation
function lazyLoadLive2D() {
    const observer = new IntersectionObserver((entries) => {
        entries.forEach(entry => {
            if (entry.isIntersecting) {
                initializeLive2D();
                observer.disconnect();
            }
        });
    });

    observer.observe(document.body);
}

CDN and Resource Management¶

Use reliable CDNs (jsDelivr, unpkg)
Implement fallback mechanisms
Consider local hosting for production

🔧 Troubleshooting Common Issues¶

Loading Problems¶

Issue: Character doesn't appear - Check browser console for errors - Verify CDN accessibility - Ensure correct model paths

Issue: Slow loading - Optimize character size settings - Implement delayed loading - Use compressed models

Browser Compatibility¶

Supported: Chrome 60+, Firefox 55+, Safari 12+
Issues: IE not supported
Mobile: Limited support on some devices

📈 Advanced Features¶

Integration with Analytics¶

function trackLive2DInteractions() {
    const canvas = document.getElementById('live2dcanvas');
    if (canvas) {
        canvas.addEventListener('click', function() {
            // Google Analytics 4
            gtag('event', 'live2d_interaction', {
                'event_category': 'engagement',
                'event_label': 'character_click'
            });
        });
    }
}

Custom Message System¶

const customMessages = {
    welcome: "Welcome to our site! 🎉",
    scroll: "Keep exploring! There's more below 📜",
    idle: "Need help with anything? Just click me! 😊",
    goodbye: "Thanks for visiting! Come back soon! 👋"
};

function showCustomMessage(type) {
    const message = customMessages[type] || customMessages.idle;
    showMessage(message);
}

🎯 Best Practices¶

User Experience¶

Don't make characters too large or intrusive
Provide easy way to disable if needed
Ensure accessibility compliance
Test across different devices and browsers

Performance¶

Load characters after critical content
Use appropriate sizing for target audience
Monitor impact on Core Web Vitals
Implement graceful degradation

Legal and Licensing¶
