Unreal Python 菜单扩展
-
使用Python脚本化运行虚幻编辑器 https://dev.epicgames.com/documentation/zh-cn/unreal-engine/scripting-the-unreal-editor-using-python
-
API https://dev.epicgames.com/documentation/en-us/unreal-engine/PythonAPI
-
生成unreal.py脚本
- Project Settings -> Plugings -> python -> Developer Mode(all users) 勾选
-
vscode 添加unreal.py脚本
-
vscode打开setting.json配置 添加
-
"python.analysis.extraPaths": ["XXX\\Intermediate\\PythonStub"],
-
-
使用Python脚本注册菜单
-
import unrealdef RegisterMenus(name: str, command: str, tool_tip: str = ""):tool_menus = unreal.ToolMenus.get()# 先尝试移除已经存在的菜单项，避免重复调用添加tool_menus.remove_entry(unreal.Name("LevelEditor.MainMenu.Python"), unreal.Name(name), unreal.Name(name))tool_menu = tool_menus.find_menu(unreal.Name("LevelEditor.MainMenu"))main_menu = tool_menu.add_sub_menu(unreal.Name("LevelEditor.MainMenu"), unreal.Name("Python"), unreal.Name("Python"), unreal.Name("Python"), unreal.Name("Python Menu"))entry = unreal.ToolMenuEntry(name=unreal.Name(name), type=unreal.MultiBlockType.MENU_ENTRY)entry.set_label(unreal.Text(name))entry.set_tool_tip(unreal.Text(tool_tip))entry.set_string_command(unreal.ToolMenuStringCommandType.COMMAND, unreal.Name(""), command)main_menu.add_menu_entry(unreal.Name(name), entry)tool_menus.refresh_all_widgets()RegisterMenus("Clear Log", "py clear_log.py", "Clear the log")

终结
- 生成的unreal.py脚本有80万行 导致代码提示 跳转很不好用
- 同一个类型 很多C++有的 python不提供
- 功能缺失严重 稍微复杂一点的功能需要在C++提供接口
- 菜单扩展这种功能 还不如直接用插件方式
