Figma2cocos

Skill ProdaZhang/figkit/figma2cocos

把 figma2html 管线产的 IR(.ui.json 像素快照 + flow.json 交互声明)落到 Cocos Creator 3.x —— TS 运行时解释器(组件加载 ui.json 动态建节点树 + flow 绑定器)+ python 离线校验器(引用完整性 + 资产清单)。要在 Cocos 工程里还原 figma 界面与交互(底屏+弹窗/守卫/列表/勾选)时使用;capture 本身归 figma2html。From its SKILL.md

figma2cocos — figma IR → Cocos Creator 3.x

这个 skill 干什么

figma2html 已把 figma 帧变成 .ui.json(像素真值)+ flow.json(声明的交互)。本 skill 是这套 IR 的 Cocos 落地端:

  • TS 运行时解释器(runtime/):FigmaUI 组件读 JsonAsset(cap)动态建节点树(Graphics/Label/Sprite); FlowBinder 读 flow.json 组装"底屏常驻 + 弹窗叠加 + 事件 + guard + 列表克隆 + checkbox",域内语义走 FigmaAppHook(对齐 assemble.js 的 APPHOOK)。
  • python 离线校验器(scripts/ui_check.py):不开 Cocos 就能测的部分——IR/flow 引用完整性 + 资产清单。

分工:capture / flow 编写规范 → figma2html;HTML 落地 → figma2html;Cocos 落地 → 本 skill

内容

runtime/    parse-css.ts(rgba/渐变/radius四角/border/shadow 解析,纯函数)
            figma-ui.ts(@ccclass FigmaUI:cap→节点树;buildSubtree=弹窗抽子树;paintRect 复用)
            flow-binder.ts(@ccclass FlowBinder:flow→层/事件/guard/列表/勾选;FigmaAppHook 注册口)
references/ mapping.md(IR→Creator 映射全表 + 坐标转换推导 + known-loss 表 + 集成冒烟清单)
scripts/    ui_check.py(离线校验:caps 可载入、el id 引用完整、列表模板行、assets-manifest.json)
            tests/(run_all.py 发现式 runner + test_ui_check.py;fixtures/=figma2html login 三屏夹具)

用法(管线)

  1. capture(figma2html):figma 帧 → screen-*.ui.json ×N + 手写 flow.json + 导出图片素材。
  2. 离线校验:python scripts/ui_check.py <flow.json> <capDir> —— 全部引用过了才进 Cocos; 顺手产出 assets-manifest.json(去重图片清单)。
  3. 资产导入:manifest 里的图放进 assets/resources/<assetRoot>/(保持 _assets/... 路径、文件名 stem 不变); .ui.json / flow.json 拷进工程任意 assets 目录(Creator 自动导成 JsonAsset,名为路径 stem 如 screen-login.ui)。
  4. 挂组件:Canvas designResolution=cap.w×cap.h;根节点(锚(0,1)+Widget 左上对齐)挂 FigmaUI(单屏预览,拖 capAsset)或 FlowBinder(整流程,拖 flowAsset + capAssets[])。
  5. hook:域内语义(数据→行、选中回填、状态色)写一个组件,在其 onLoadFlowBinder.registerHook({ register(app){ app.registerActions({send, selectServer, onGuardFail, ...}) }, init(app){ app.renderRows(...) } }) —— 语义与 figma2html 的 app.js/APPHOOK 一一对应,renderRows/openModal/setFlag/getNode 同名同义。
  6. 冒烟:按 references/mapping.md §6 清单逐项核(几何对照截图、事件逐个点验)。

硬约束

  • 坐标转换是本 skill 的命门:IR 是 y 向下/左上原点的绝对 px,Creator 是 y 向上/锚点系。 约定 = 每节点锚 (0,1),child.position = (dx, -dy);旋转节点换锚 (0.5,0.5) 补偿。改动前必读 references/mapping.md §2/§3
  • TS 验证等级(2026-07-06):三件 runtime TS 已过 严格类型编译门(tsc --noEmit 对 Cocos 官方 @cocos/creator-types engine 声明,含 @ccclass 装饰器路径;故意错用 API 会被抓=门有牙);Creator 内实机运行仍未验证,交付态 = 源码 + 集成说明(mapping.md 顶部有声明);python 侧 python scripts/tests/run_all.py 必须全绿才算校验器可用。
  • 引擎 vs hook 边界不破:runtime 只管结构与机制,任何"某个项目的某块颜色/数据"都进 hook,不进引擎。
  • 项目无关、可移植;中文文档、英文标识符;UTF-8 无 BOM。
  • 上游 IR 契约(字段、已知限制如实例内 rot=0)以 figma2html references/ 为准,本 skill 不复制不改写。
