解决方案
对于您似乎要在此处尝试的非常特定的应用程序，您还可以使用 attrFieldSliderGrp 控件，该控件正是用于将数字从gui直接传递到对象属性.
要执行此操作，您需要确保在要编辑对象时，所有滑块都需要知道其名称.懒惰的方法是确保该功能仅适用于所选项目-尽管这不太可能是您想要的.
在按钮之间传递信息有些棘手(出于此处详细的原因. 将需要确保控件都知道正在处理哪个对象并对其进行操作.尽管通常在这种情况下，一个类对于简单的GUI而言是多余的，但是该类提供了一种非常简单的方式来处理该对象. >
这是一个简化的示例:
import maya.cmds as cmds
class ShapeUI(object): # remember to inherit from object in python 2 classes!
WINDOW_NAME = "myWindowID" # put this up here so all copies of this class share it
def __init__(self):
# you need to remember the name of the object you want to work on
self.active_shape = None
self.layout()
def layout(self):
if cmds.window(self.WINDOW_NAME, exists=True):
cmds.deleteUI(self.WINDOW_NAME)
cmds.window(self.WINDOW_NAME, title="User Interface", resizeToFitChildren=True)
cmds.columnLayout(adjustableColumn=True)
cmds.button(label="Sphere", command=self.mySphere)
cmds.button(label="Cube", command=self.myCube)
cmds.button(label = 'delete active', command = self.myDelete)
cmds.separator(h=20, style="none")
# you need to remember the ids of the sliders so you can query their values
self.TranslateX = cmds.intSliderGrp(
label="Translate X ", field=True, min=1, max=100, value=0, cc=self.move_active)
self.TranslateY = cmds.intSliderGrp(
label="Translate Y ", field=True, min=1, max=100, value=0, cc=self.move_active)
self.TranslateZ = cmds.intSliderGrp(
label="Translate Z ", field=True, min=1, max=100, value=0, cc=self.move_active)
cmds.showWindow(self.WINDOW_NAME)
def mySphere(self, *_): # _ is python slang for "I will ignore this argument"
self.active_shape = cmds.polySphere()[0]
# for good measure, change the window title to the name of the active object
cmds.window(self.WINDOW_NAME, e=true, title = self.active_shape)
def myCube(self, *_):
self.active_shape = cmds.polyCube()[0]
cmds.window(self.WINDOW_NAME, e=true, title = self.active_shape)
def myDelete(self, *_):
if self.active_shape:
cmds.delete(self.active_shape)
self.active_shape = None
cmds.window(self.WINDOW_NAME, e=true, title = "nothing selected")
def move_active(self, *_):
# you could do separate functions for each slider,
# but in this case it's easler to do the same one everwhere
# using the stored widget names and the stored shape
if self.active_shape:
tx = cmds.intSliderGrp(self.TranslateX, q=True, v=True)
ty = cmds.intSliderGrp(self.TranslateY, q=True, v=True)
tz = cmds.intSliderGrp(self.TranslateZ, q=True, v=True)
cmds.xform(self.active_shape, t=(tx, ty, tz))
else:
print "create a shape before adjusting sliders"
ui=ShapeUI()
基本技巧是所有函数都使用self，因此它们可以访问变量self.active_shape，self.TranslateX等.
I am trying to use the following sliders for the Colour, Translate, Rotate and Scale for the shapes I have in this code. Is there a way I can control all the shapes with these sliders? I can't seem to figure it out I've tried everything that I could. I would like to do this with maybe a function but any solution is helpful Any help would be appreciated, thank you.

解决方案
For the very specific application you seem to be trying here, you can also short-circuit some of the work using the attrFieldSliderGrp control which is precisely for passing numbers directly from a gui to an object attribute.
To make this work you'll need to make sure that when you want to edit an object, all of the sliders will need to know it's name. The lazy method would be to make sure that the function just works on the selected item -- though that's not likely to be what you want.
Passing information between the buttons is a bit tricky (for reasons detailed here. Basically you'll need to make sure that the controls all know which object is being worked on and do their work on it. Although in general a class is overkill for simple GUI in this case the class provides an pretty simple way to handle this.
Here's a cut-down example of how it can be done:
import maya.cmds as cmds
class ShapeUI(object): # remember to inherit from object in python 2 classes!
WINDOW_NAME = "myWindowID" # put this up here so all copies of this class share it
def __init__(self):
# you need to remember the name of the object you want to work on
self.active_shape = None
self.layout()
def layout(self):
if cmds.window(self.WINDOW_NAME, exists=True):
cmds.deleteUI(self.WINDOW_NAME)
cmds.window(self.WINDOW_NAME, title="User Interface", resizeToFitChildren=True)
cmds.columnLayout(adjustableColumn=True)
cmds.button(label="Sphere", command=self.mySphere)
cmds.button(label="Cube", command=self.myCube)
cmds.button(label = 'delete active', command = self.myDelete)
cmds.separator(h=20, style="none")
# you need to remember the ids of the sliders so you can query their values
self.TranslateX = cmds.intSliderGrp(
label="Translate X ", field=True, min=1, max=100, value=0, cc=self.move_active)
self.TranslateY = cmds.intSliderGrp(
label="Translate Y ", field=True, min=1, max=100, value=0, cc=self.move_active)
self.TranslateZ = cmds.intSliderGrp(
label="Translate Z ", field=True, min=1, max=100, value=0, cc=self.move_active)
cmds.showWindow(self.WINDOW_NAME)
def mySphere(self, *_): # _ is python slang for "I will ignore this argument"
self.active_shape = cmds.polySphere()[0]
# for good measure, change the window title to the name of the active object
cmds.window(self.WINDOW_NAME, e=true, title = self.active_shape)
def myCube(self, *_):
self.active_shape = cmds.polyCube()[0]
cmds.window(self.WINDOW_NAME, e=true, title = self.active_shape)
def myDelete(self, *_):
if self.active_shape:
cmds.delete(self.active_shape)
self.active_shape = None
cmds.window(self.WINDOW_NAME, e=true, title = "nothing selected")
def move_active(self, *_):
# you could do separate functions for each slider,
# but in this case it's easler to do the same one everwhere
# using the stored widget names and the stored shape
if self.active_shape:
tx = cmds.intSliderGrp(self.TranslateX, q=True, v=True)
ty = cmds.intSliderGrp(self.TranslateY, q=True, v=True)
tz = cmds.intSliderGrp(self.TranslateZ, q=True, v=True)
cmds.xform(self.active_shape, t=(tx, ty, tz))
else:
print "create a shape before adjusting sliders"
ui=ShapeUI()
the basic trick is that all the functions use self so they have access to the variables self.active_shape , self.TranslateX and so on.
