Maya Python Game and Film Programming Guide Reading Notes-Chapter 2

1. Set object attributes and read object attributes (setAttr & getAttr)

Code:

import maya.cmds
lco = maya.cmds.spaceLocator()[0] #创建定位器

#Get attributes

sx = maya.cmds.getAttr(lco+ ".scaleX")
print(sx)

#Set attributes

sx*= 2
maya.cmds.setAttr(lco+".scaleX")

2. Set the connection attribute (connectAttr & disconnectAttr)
code:

import maya.cmds
sphere = maya.cmds.polySphere()[0]
cube  = maya.cmds.polyCube()[0]

#Connect the y-axis rotation property of the cube to the y-axis movement property of the sphere

maya.cmds.connectAttr(cube + ".ry",sphere + ".ty")

maya.cmds.select(cube)

#Disconnect attribute

maya.cmds.disconnectAttr(cube + ".ry" , sphere + ".ty")
