blender 2.92 python重写

Question

关于这个问题，我已经看到了相当多的问题，但我还不能理解它。

所以这里有一个具体的例子。

我创建了一个立方体，并在编辑模式下添加了循环剪切。不客气!

我从info窗口复制代码并在脚本中试用，得到不祥的RuntimeError: Operator bpy.ops.mesh.loopcut_slide.poll()预期的view3d region & editmesh错误消息。

我现在明白了，它首先是通过重写来给python提供正确的上下文。可惜，我不知道该怎么做！

代码如下：

import bpy
import os

os.system("cls")

# remove the default cube...
objs = bpy.data.objects
for obj in objs:
    if obj.name.find("Cube") == 0:
        bpy.data.objects.remove(obj, do_unlink=True)

# add a cube!
bpy.ops.mesh.primitive_cube_add(size=2, enter_editmode=True, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
# do something to it to be sure that we have it...
bpy.data.objects['Cube'].scale[0] = 10

# THE CODE BELOW GIVES THE RuntimeError: Operator bpy.ops.mesh.loopcut_slide.poll() expected a view3d region & editmesh error message.

# What is the override code I have to use to fix it????????

bpy.ops.mesh.loopcut_slide(MESH_OT_loopcut={"number_cuts":16, "smoothness":0, "falloff":'INVERSE_SQUARE', "object_index":0, "edge_index":4, "mesh_select_mode_init":(True, False, False)}, TRANSFORM_OT_edge_slide={"value":0, "single_side":False, "use_even":False, "flipped":False, "use_clamp":True, "mirror":True, "snap":False, "snap_target":'CLOSEST', "snap_point":(0, 0, 0), "snap_align":False, "snap_normal":(0, 0, 0), "correct_uv":True, "release_confirm":False, "use_accurate":False})

import bpy      
import os

os.system("cls")


objs = bpy.data.objects
for obj in objs:
    if obj.name.find("Cube") == 0:
        bpy.data.objects.remove(obj, do_unlink=True)

# add a cube!
bpy.ops.mesh.primitive_cube_add(size=2, enter_editmode=True, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
# do something to it to be sure that we have it...
bpy.data.objects['Cube'].scale[0] = 10



for area in bpy.context.screen.areas:
        if area.type == 'VIEW_3D':
            for region in area.regions:
                if region.type == 'WINDOW':
                    override = {'area': area, 'region': region, 'edit_object':bpy.context.edit_object}


                    bpy.ops.mesh.loopcut_slide(override,MESH_OT_loopcut={"number_cuts":16, "smoothness":0, "falloff":'INVERSE_SQUARE', "object_index":0, "edge_index":4, "mesh_select_mode_init":(True, False, False)}, TRANSFORM_OT_edge_slide={"value":0, "single_side":False, "use_even":False, "flipped":False, "use_clamp":True, "mirror":True, "snap":False, "snap_target":'CLOSEST', "snap_point":(0, 0, 0), "snap_align":False, "snap_normal":(0, 0, 0), "correct_uv":True, "release_confirm":False, "use_accurate":False})
