This approach: + +- Renders HTML content to a CPU-accessible bitmap +- Converts bitmap data to MonoGame Texture2D +- Displays texture within Gwen.NET ImagePanel + +### Memory Management + +- HTML renderers are automatically disposed when panels are destroyed +- Resource cleanup is handled by HtmlManager +- Texture memory is managed through the existing IGameTexture system + +### Performance Considerations + +- Updates only occur when content changes (dirty rectangle optimization planned) +- Multiple HTML panels can share rendering resources +- Background rendering minimizes impact on main game thread + +## Troubleshooting + +### Common Issues + +1. **HTML content not displaying**: Ensure HtmlManager.Initialize() is called before creating panels +2. **Input events not working**: Check ForwardMouseEvents/ForwardKeyboardEvents properties +3. **Resource loading failures**: Verify HTML content directory exists and is accessible + +### Debugging + +Enable console logging to see HTML manager operations: + +```csharp +// HTML manager operations are logged to console +// Look for messages starting with "[HtmlManager]" and "[HtmlRenderer]" +``` + +## Examples + +### Simple Game Panel + +```csharp +var gamePanel = HtmlUIExample.CreateSampleHtmlPanel(parentControl); +// Creates a complete game interface with stats, buttons, and styling +``` + +### Notification System + +```csharp +var notification = HtmlUIExample.CreateNotificationPanel( + parentControl, + "Level up!", + "success" +); +// Creates a styled notification panel +``` + +### Dynamic Minimap + +```csharp +var minimap = HtmlUIExample.CreateMinimapPanel(parentControl); +// Creates an animated minimap with player position tracking +``` + +## Integration with Game Logic + +### Event Handling + +HTML panels can trigger game events through the parent Gwen control system: + +```csharp +htmlPanel.OnHtmlLoaded += () => { + // HTML content finished loading +}; + +htmlPanel.OnHtmlLoadFailed += (error) => { + // Handle loading errors +}; +``` + +### Dynamic Content Updates + +Update HTML content dynamically based on game state: + +```csharp +// Update player stats in HTML +var newHtml = $@" +

Future enhancements may include: + +- **JavaScript Bridge**: Two-way communication between game and HTML +- **Template System**: Reusable HTML templates for common UI patterns +- **Animation Support**: Hardware-accelerated CSS animations +- **WebGL Integration**: 3D content within HTML panels +- **Responsive Design**: Automatic scaling for different screen sizes + +## Contributing + +When contributing to the HTML UI integration: + +1. Maintain compatibility with existing Gwen.NET architecture +2. Follow the established patterns for resource management +3. Add comprehensive tests for new functionality +4.
