Yes it is ugly,
Some time ago somebody asked on the list making trees on geo to
manipulate the transforms when the geo was reading a cache file. I did
some quick script example. Maybe you can find this a good start:

prefDict = {"scripting.cmdlog": False} # more key - value pairs can
be added to this dictionary ex: "interaction.autoinspect": False
def outer(func):
@functools.wraps(func)
def inner(*args, **kwargs):
# Get pref values
tmpPrefs = {}
for k, v in prefDict.iteritems():
tmpPrefs[k] = xsi.GetValue("preferences." + k)
xsi.SetValue("preferences." + k, v, "")
try:
# Run original function
return func(*args, **kwargs)
finally:
# restore pref values
for k, v in tmpPrefs.iteritems():
xsi.SetValue("preferences." + k, v, "")
return inner
return outer
def _moveToFirstFrame():
inFrame = xsi.GetValue('PlayControl.In')
msgStr = ""
msgStr += "Do you want to move to first frame before creating \n"
msgStr += "the manipulator null ?"
if MSG(msgStr, c.siMsgYesNo | c.siMsgQuestion, "MOVE TO FIRST FRAME
?")==6:
xsi.SetValue('PlayControl.Current', inFrame)
def _centerNullOnGeo(inNull, inGeo):
c = xsi.GetBBox(inGeo, True)
inNull.Kinematics.Global.Parameters('posx').Value = (c(
"UpperBoundX" ) + c( "LowerBoundX" )) / 2

I would say that this is where a more functional programming approach
may be neater. That way you can hide all the nastyness away in small
functions elsewhere and then just stick a suspiciously tidy looking
map() in the main Execute.

Prepare yourself for some ugly, ugly code when it comes to
ICE! Nice long command names as well. :)
Indeed. A mix of OM and commands is necessary. You can query ports
via OM but you'll need to use commands to connect stuff. Have fun
you'll find it to be frustrating.
