1、Python And UE

a. API文档

Unreal Python API Documentation — Unreal Python 5.0 (Experimental) documentation (unrealengine.com)
b. 开启插件

c. 插件设置

d.VSCode 配置

1、在项目的\Intermediate\PythonStub文件夹下生成了unreal.py
2、VSCode安装Python
3、VSCode的Python的配置

4、配置信息
&#34;python.autoComplete.extraPaths&#34;: [
&#34;E:\\UE\\Develop\\Project\\MyNaniteTestProject5\\Intermediate\\PythonStub&#34;
],
&#34;python.jediEnable&#34;: false,
&#34;jupyter.enableExtendedKernelCompletions&#34;: true,
&#34;python.analysis.extraPaths&#34;: [
&#34;E:\\UE\\Develop\\Project\\MyNaniteTestProject5\\Intermediate\\PythonStub&#34;
  ]
5、重启VSCode和Ue项目
6、实现了FBX和Datasmith的数据导入处理
7、示例程序
import unreal
#FBX导入
def build_static_mesh_import_options():
options = unreal.FbxImportUI()
options.set_editor_property(&#39;automated_import_should_detect_type&#39;, False)
options.set_editor_property(&#39;mesh_type_to_import&#39;, unreal.FBXImportType.FBXIT_STATIC_MESH)
options.set_editor_property(&#39;import_as_skeletal&#39;, False)  # 是否当作骨骼物体来导入
options.set_editor_property(&#39;import_animations&#39;, False)
options.set_editor_property(&#39;import_materials&#39;, True)
options.set_editor_property(&#39;import_textures&#39;, True)
      #上面是设置fbx import UI的数据
options.static_mesh_import_data.set_editor_property(&#39;import_translation&#39;, unreal.Vector(0.0, 0.0, 0.0))
options.static_mesh_import_data.set_editor_property(&#39;import_rotation&#39;, unreal.Rotator(0, 0, 0))
options.static_mesh_import_data.set_editor_property(&#39;import_uniform_scale&#39;, 1.0)
options.static_mesh_import_data.set_editor_property(&#39;combine_meshes&#39;, False)
options.static_mesh_import_data.set_editor_property(&#39;generate_lightmap_u_vs&#39;, False)
options.static_mesh_import_data.set_editor_property(&#39;auto_generate_collision&#39;, False)
options.static_mesh_import_data.set_editor_property(&#39;one_convex_hull_per_ucx&#39;, True)
options.static_mesh_import_data.set_editor_property(&#39;reorder_material_to_fbx_order&#39;, True)
#上面是设置static_mesh_import_data的数据
return options

#Datasmith导入
def build_Datasmith_import_options():
options = unreal.DatasmithImportBaseOptions()
options.set_editor_property(&#39;include_animation&#39;, False)
options.set_editor_property(&#39;include_camera&#39;, False)
options.set_editor_property(&#39;include_geometry&#39;, True)
options.set_editor_property(&#39;include_light&#39;, False)
options.set_editor_property(&#39;include_material&#39;, True)
#上面是设置 UI的数据
#options.static_mesh_import_data.set_editor_property(&#39;import_translation&#39;, unreal.Vector(0.0, 0.0, 0.0))
#options.static_mesh_import_data.set_editor_property(&#39;import_rotation&#39;, unreal.Rotator(0, 0, 0))
#options.static_mesh_import_data.set_editor_property(&#39;import_uniform_scale&#39;, 1.0)
#options.static_mesh_import_data.set_editor_property(&#39;combine_meshes&#39;, False)
#options.static_mesh_import_data.set_editor_property(&#39;generate_lightmap_u_vs&#39;, False)
#options.static_mesh_import_data.set_editor_property(&#39;auto_generate_collision&#39;, False)
#options.static_mesh_import_data.set_editor_property(&#39;one_convex_hull_per_ucx&#39;, True)
#options.static_mesh_import_data.set_editor_property(&#39;reorder_material_to_fbx_order&#39;, True)
#上面是设置static_mesh_import_data的数据
return options
def creatImportTask(filename, Destination_path, options=None,factory = None):
importtask = unreal.AssetImportTask()
importtask.set_editor_property(&#34;automated&#34;, True)
importtask.set_editor_property(&#39;destination_path&#39;, Destination_path)
importtask.set_editor_property(&#39;filename&#39;, filename)
importtask.set_editor_property(&#39;replace_existing&#39;, True)
importtask.set_editor_property(&#39;options&#39;, options)
importtask.set_editor_property(&#39;save&#39;, True)
importtask.set_editor_property(&#39;factory&#39;,factory)
return importtask
def execute_import_tasks(tasks):
asset_tools = unreal.AssetToolsHelpers.get_asset_tools()  # 创建一个资产工具
asset_tools.import_asset_tasks([tasks])
Destination_path = &#34;/Game/texture/&#34;
StaticMesh_path = &#34;E:/ue/data/bunny.obj&#34;
DataSmith_path=&#34;E:/ue/data/bunny.udatasmith&#34;
#FBX的导入
#options = build_static_mesh_import_options()
#execute_import_tasks(creatImportTask(StaticMesh_path, Destination_path, options,None))
##Datasmith导入
datasmithImportOptions =  unreal.DatasmithImportOptions();
datasmithImportOptions.base_options = build_Datasmith_import_options();
#需要指定的导入工厂类型  通过调试ue源码发现，需要指定个工厂类
datasmithFactory = unreal.DatasmithImportFactory();
execute_import_tasks(creatImportTask(DataSmith_path, Destination_path, datasmithImportOptions , datasmithFactory))
8、python的执行
8.1 命令行执行
UnrealEditor-Cmd.exe &#34;E:\UE\projectTest.uproject&#34; -run=pythonscript -script=&#34;C:\\Users\\Administrator\\Desktop\\UePython\\PythonUE.py&#34;
8.2 编辑器界面下菜单栏 Tools->ExecutePython Script...
