Hello again, update....
I managed to make it work a bit better but still not as I need to...
thanks to your suggestions I'm able now to check channels and create
locators, constraints etc ...
So I have a script that checks everything and if selections have both
rotations and translations available, it runs the function properly; if
there is something locked it stop and warn. And I can also have several
objects selected.
Now Im trying something more...
I'd like the script to check what channel is available and act accordingly,
if there is only translation, it contstraint just the translations, if only
rotations available, it works only with that....
I ended up make it work by adding the skipRotation or skipTranslation flag
but it works only selecting one object at a time, if I select several
object in the scene where some has both T and R and some had just
translation and no rotations, it fails for all the object but work only for
the first one....
I guess I need a loop or another condition which checks inside my 'userSel'
variable but not sure how to do.....
Probably the problem is in the sel[0] call, which looks only on the first
obj selected, I tried to add a loop but it works only with translation,
seems that it doesnt connect the rotations
anyways this is what I have so far which works only selecting obj 1 by 1:
# this works fine BUT 1 obj x time
import maya.cmds as mc
LocList = []
userSel = []
len(userSel)
sel = []
sel = mc.ls(sl=1)
userSel.append(sel)
if len(sel) != 0:
_has_trans = mc.getAttr (sel[0]+'.translate', settable=True)
_has_rot = mc.getAttr (sel[0]+'.rotate', settable=True)
else :
mc.warning('Please make a selection')
# check if there is rotations
# create a loc for ech selected obj and constraint to it
if _has_rot ==1 and _has_trans ==1:
for obj in sel:
newLoc = mc.spaceLocator()
newCon = mc.parentConstraint(obj, newLoc, mo=0)
LocList.append(newLoc)
elif _has_rot ==0 and _has_trans ==1:
for obj in sel:
newLoc = mc.spaceLocator()
newCon = mc.parentConstraint(obj, newLoc, mo=0, sr=['x', 'y', 'z'])
LocList.append(newLoc)
elif _has_rot ==1 and _has_trans ==0:
for obj in sel:
newLoc = mc.spaceLocator()
newCon = mc.parentConstraint(obj, newLoc, mo=0, st=['x', 'y', 'z'])
LocList.append(newLoc)
# select all new Loc
if len(sel) != 0:
for loc in LocList:
mc.select (loc, add=1)
start = mc.playbackOptions(q=True, min=True)
end = mc.playbackOptions(q=True, max=True)
mc.bakeResults(sm=1, sr=1, t=(start, end))
#else:
#mc.warning('Please make a selection')
for loc in LocList:
mc.select (loc, add=1)
mc.delete(cn=1)
# reverse connection
if _has_rot ==1 and _has_trans ==1:
for idx, item in enumerate(LocList):
ctl = item
makeParentCons = mc.parentConstraint(ctl, userSel[0][idx], mo=True, w=1)
elif _has_rot ==0 and _has_trans ==1:
for idx, item in enumerate(LocList):
ctl = item
makeParentCons = mc.parentConstraint(ctl, userSel[0][idx], mo=True,
w=1, sr=['x', 'y', 'z'])
elif _has_rot ==1 and _has_trans ==0:
for idx, item in enumerate(LocList):
ctl = item
makeParentCons = mc.parentConstraint(ctl, userSel[0][idx], mo=True,
w=1, st=['x', 'y', 'z'])
