Thanks for the help guys.
After a couple more hours exploring this, I've tried everything I can
think of, but I'm still not getting it.
Probably missing some small thing:
tmpJnts = ls (sl = 1)
numJnts = len(tmpJnts)
print tmpJnts
[nt.Joint(u'joint1'), nt.Joint(u'joint2'), nt.Joint(u'joint3'),
nt.Joint(u'joint4'), nt.Joint(u'joint5')]
print tmpJnts.name() # Fails - 'list' object has no attribute
'name' (I get that)
print tmpJnts[0].name() # Works
# Copy joints to space separated list - avoid adding a trailing space:
jntStringList = ''
count = 1
for jnt in tmpJnts:
if count < numJnts:
jntStringList += jnt.name() + ' '
else:
print ('else add jnt')
jntStringList += jnt.name()
count += 1
print jntStringList
# joint1 joint2 joint3 joint4 joint5
print jntStringList[0]
# j (First Letter)
print jntStringList[0].name() #Fails because it is text object
('unicode' object has no attribute 'name') (I get that)
jntSplitList = jntStringList.split (' ')
print len(jntSplitList)
print jntSplitList
[u'joint1', u'joint2', u'joint3', u'joint4', u'joint5']
print jntSplitList[0]
#joint1
select (jntSplitList[0]) #Works because select is a Maya command which
takes text as arg -
# After converstion to a list and back, the attr method fails because
the object is text - "it's got no maya special goodness"
print jntSplitList[0].name() #Fails - 'unicode' object has no
attribute 'name' (I get that)
#--------------------------------
HERE'S THE PROBLEM:
#--------------------------------
#cast strings back to pymel objects:
print Attribute(jntSplitList[0]).name() # Fails - Determined type is
Joint, which is not a subclass of desired type Attribute
if Attribute(jntSplitList[0]).hasAttr('liw'):
print ('Has Attr')
# Fails - Determined type is Joint, which is not a subclass of desired
type Attribute
for jnt in jntSplitList:
myNode = PyNode(jnt)
if jnt.hasAttr('liw'):
print ('Has Attr')
# Error: AttributeError: file <maya console> line 3: 'unicode' object
has no attribute 'hasAttr' #
#------------------------------------------------
#------------------------------------------------
Also, trying to use the name() method to build the string list failed:
#------------------------------------------------
tmpJnts = ls (sl = 1)
# Copy joints to space separated list:
jntStringList = ''
jntStringList = tmpJnts[0].name
print jntStringList
<bound method Joint.name of nt.Joint(u'joint1')>
print len(jntStringList)
# Error: TypeError: file <maya console> line 1: object of type
'instancemethod' has no len() #
jntStringList = ''
jntStringList += str(tmpJnts[0].name)
<bound method Joint.name of nt.Joint(u'joint1')>
print len(jntStringList)
