 当前优先推荐轻量网页工具，因为它能更快完成 `.map` 可视化编辑，且不影响引擎编译链路。
 
+## 当前实现
+
+首版网页工具已建立：
+
+```text
+tools/map_editor/
+├─ index.html
+├─ styles.css
+├─ app.js
+└─ README.md
+```
+
+本地运行：
+
+```powershell
+python -m http.server 8787
+```
+
+打开：
+
+```text
+http://127.0.0.1:8787/tools/map_editor/
+```
+
+当前能力：
+
+- 从仓库静态服务加载 `game/assets/map/stage_01.map`。
+- 通过文件选择打开任意 `.map`。
+- Canvas 可视化 world、camera、player spawn、collision、rect、tile_rect、battle zone、spawn。
+- 对象列表选择和画布点击选择。
+- 网格吸附拖动对象。
+- 属性面板编辑选中对象的数值或文本。
+- 新增/删除 tileset、layer、collision、tile_rect、battle zone、spawn。
+- 导出兼容 `StageMapLoader` 的 `.map` 文本。
+
+浏览器安全限制下，纯静态网页不能直接覆盖本地源文件；当前通过 Download 导出 `.map`。后续部署到服务器时，可以增加一个保存接口，把编辑器导出的文本写回服务端文件或数据库。

 ## 数据边界
 
 编辑器只负责编辑 `.map` 数据，不负责：

+# Map Editor
+
+Static browser-based editor for the game's `.map` files.
+
+## Run Locally
+
+From the repository root:
+
+```powershell
+python -m http.server 8787
+```
+
+Open:
+
+```text
+http://127.0.0.1:8787/tools/map_editor/
+```
+
+The editor can fetch `game/assets/map/stage_01.map` when served from the repo root. It can also open any `.map` file through the file picker.
+
+## Current Scope
+
+- Open `.map` text files.
+- Visualize world, camera, player spawn, collision, stage rects, tile rects, battle zones, and spawn points.
+- Select objects from the canvas or object list.
+- Drag objects on the canvas with grid snapping.
+- Edit selected object numeric properties.
+- Add/delete collision rectangles, tile rectangles, battle zones, and spawn points.
+- Download a serialized `.map` file compatible with `StageMapLoader`.
+
+## Limitations
+
+- Browser security prevents direct overwrite of the original local file. Use Download and replace the project `.map` manually, or deploy with a server-side save endpoint later.
+- Tileset image preview is not implemented yet; tile rects use fallback colors.
+- Undo/redo and multi-select are not implemented yet.
