如何在计算中使用滑块值？

Question

我有一段代码会产生噪音。噪声在 0.0 到 1.0 范围内产生。只要我设置一个定义的数字，代码就可以工作。如果我允许用户 select 最大范围的数字与滑块停止工作。

我有一个滑块可以替换亮度计算中的值 1.0。一旦我将 Brightness 中的 1.0 值替换为一个名为 noiseAttribute 的滑块生成值，代码就会中断。它没有给出任何错误并且技术上运行但只是使对象变黑而不是锁定颜色值。

import maya.cmds as cmds
import random
import functools

colorList = cmds.ls('colorSet*')

def createUI( pWindowTitle, pNoiseVerts):

    windowID = 'myWindowID'

    if cmds.window( windowID, exists=True ):
        cmds.deleteUI(windowID )

    cmds.window( windowID, title=pWindowTitle, s=False, rtf=True )
    cmds.rowColumnLayout( numberOfColumns=1, columnWidth=[(1,200)])

    cmds.text(label= 'Max Value Lock')
    noiseAttribute = cmds.floatSliderGrp( min=0.0, max=1.0, value=1, field=True)

    cmds.button( label='Noise', command=functools.partial (addNoise) )
    def cancelCallback( *pArgs ):
        if cmds.window( windowID, exists=True ):
            cmds.deleteUI( windowID)
    cmds.button( label='Cancel', command=cancelCallback )
    cmds.showWindow()


def pNoiseVerts(object, noiseAttribute):
    verts = range(cmds.polyEvaluate(object, vertex=True))
    random.shuffle(verts)

    for vertex in verts:
        cmds.select(object + '.vtx[' + str(vertex) + ']')

        brightness = random.uniform(0.0, noiseAttribute)

        cmds.polyColorPerVertex(rgb=(brightness, brightness, brightness))
        cmds.setAttr(object + '.displayColors', True)

def addNoise(noiseAttribute, *args):
    if len(colorList) > 0:
        cmds.delete(colorList)

    objects = cmds.ls( sl=True, long=True)

    if len(objects) > 0:
        setList = cmds.ls('colorSet*')
        result = cmds.polyColorSet ( create=True, colorSet='colorSet#')
        result = cmds.polyColorPerVertex ( rgb=[0.5,0.5,0.5])  
        result = cmds.polyColorSet ( create=True, colorSet='colorSet#')

        for object in objects:
            pNoiseVerts(object, noiseAttribute)
    else:
        cmds.inViewMessage (amg='Message: <hl>Please select an object first</hl>.', pos='midCenter', fade=True )


createUI( 'Config', pNoiseVerts)

如前所述，对象变黑而不是锁定其最大颜色值。

import maya.cmds as cmds

colorList = cmds.ls('colorSet*')

def createUI(pWindowTitle):

    windowID = 'myWindowID'

    if cmds.window( windowID, exists=True ):
        cmds.deleteUI(windowID )

    cmds.window( windowID, title=pWindowTitle, s=False, rtf=True )
    cmds.rowColumnLayout( numberOfColumns=1, columnWidth=[(1,200)])

    cmds.text(label= 'Max Value Lock')
    noiseAttribute = cmds.floatSliderGrp( min=0.0, max=1.0, value=1, field=True)

    cmds.button( label='Noise', command=functools.partial(ui_addNoise, noiseAttribute) )
    def cancelCallback( *pArgs ):
        if cmds.window( windowID, exists=True ):
            cmds.deleteUI( windowID)
    cmds.button( label='Cancel', command=cancelCallback )
    cmds.showWindow()

def ui_addNoise(noiseSlider, *args):
    value = cmds.floatSliderGrp(noiseSlider, q=True, value=True)
    addNoise(value)


def pNoiseVerts(object, value):
    verts = range(cmds.polyEvaluate(object, vertex=True))
    random.shuffle(verts)

    for id in verts:
        # you should never select things in maya, pass it as variable : 
        vtx = '{}.vtx[{}]'.format(object, id)

        brightness = random.uniform(0.0, value)

        cmds.polyColorPerVertex(vtx, rgb=(brightness, brightness, brightness))
        cmds.setAttr(object + '.displayColors', True)


def addNoise(value):
    if len(colorList) > 0:
        cmds.delete(colorList)

    objects = cmds.ls( sl=True, long=True)

    if len(objects) > 0:
        setList = cmds.ls('colorSet*')
        result = cmds.polyColorSet ( create=True, colorSet='colorSet#')
        result = cmds.polyColorPerVertex ( rgb=[0.5,0.5,0.5])  
        result = cmds.polyColorSet ( create=True, colorSet='colorSet#')
