鸿蒙跨端智能填色游戏开发指南

一、系统架构设计

基于HarmonyOS的AI能力和分布式技术，构建智能填色游戏系统：
图像识别层：识别线稿区域和可填色部分

配色推荐层：根据主题和风格推荐配色方案

游戏逻辑层：管理填色进度和评分

跨端同步层：多设备间同步填色进度和作品

权限配置

// module.json5
“module”: {

"requestPermissions": [

“name”: “ohos.permission.USE_AI”,

    "reason": "使用AI模型识别线稿和推荐配色"
  },

“name”: “ohos.permission.READ_MEDIA”,

    "reason": "读取线稿图片"

四、总结与扩展

本智能填色游戏系统实现了以下核心功能：
线稿识别：自动识别可填色区域

智能配色：根据图像内容推荐配色方案

精准填色：支持点选区域填色

进度同步：多设备间同步填色进度

作品分享：分享完成的填色作品

扩展方向：
AR填色：通过AR技术将填色作品投影到现实世界

动态效果：为填色作品添加动画效果

社区画廊：建立用户作品分享社区

教育模式：结合填色教授色彩理论

3D填色：扩展支持3D模型填色

AI生成线稿：根据用户描述生成自定义线稿

通过HarmonyOS的分布式技术，我们构建了一个富有创意和教育意义的填色游戏，让用户可以在多设备间无缝切换和分享创作过程，同时享受AI技术带来的智能配色体验。
