在maya里用python代码，生成一个修改blendshape的插件

好的，以下是一个简单的示例代码，可以在Maya中自动生成BlendShape插件：

import maya.cmds as cmds

class BlendShapeUI():

    def __init__(self):
        self.window_name = 'blendShapeUI'

    def create(self):
        if cmds.window(self.window_name, exists=True):
            cmds.deleteUI(self.window_name)

        cmds.window(self.window_name, title='BlendShape UI')
        cmds.columnLayout(adjustableColumn=True)

        # 创建一个 BlendShape 节点
        cmds.text(label='Create BlendShape Node:')
        self.blendshape_field = cmds.textFieldGrp(label='BlendShape Name:', text='new_blendshape')
        cmds.button(label='Create', command=self.create_blendshape)

        # 为 BlendShape 添加目标形状
        cmds.text(label='Add Target Shapes:')
        self.target_list = cmds.textScrollList(numberOfRows=6, allowMultiSelection=True)
        cmds.button(label='Add', command=self.add_target_shape)

        # 设置目标形状的权重
        cmds.text(label='Set Target Weights:')
        self.weight_field = cmds.floatFieldGrp(label='Weight:', value1=0.0)
        cmds.button(label='Set', command=self.set_target_weight)

        cmds.setParent('..')
        cmds.showWindow()

    def create_blendshape(self, *args):
        blendshape_name = cmds.textFieldGrp(self.blendshape_field, query=True, text=True)
        cmds.blendShape(name=blendshape_name)

    def add_target_shape(self, *args):
        selected = cmds.ls(selection=True)
        cmds.textScrollList(self.target_list, edit=True, append=selected)

    def set_target_weight(self, *args):
        selected = cmds.textScrollList(self.target_list, query=True, selectItem=True)
        weight = cmds.floatFieldGrp(self.weight_field, query=True, value1=True)
        blendshape_name = cmds.textFieldGrp(self.blendshape_field, query=True, text=True)
        for shape in selected:
            cmds.blendShape(blendshape_name, edit=True, target=(shape, 1, weight))

ui = BlendShapeUI()
ui.create()

这个插件可以在Maya中创建一个新的BlendShape节点，然后添加目标形状并设置它们的权重。你可以通过修改这个代码来实现你自己的BlendShape插件。
