MatchTransformsMirrorX

## This script copies the Transforms from one object to another in pairs and mirrors them on the YoZ plane, except Scale. Like if you have 4 objects selected, A B C D, it will copy A > B and C > D.

## These are just XSI variables.
app = Application
oObjs=app.Selection

## List built from the selected objects.
oList=[x.FullName for x in oObjs] ## Softimage Selection list

## Fail safe in case the objects selection is an odd number. Gives me a warning and the name of which object will be ignored.
if len(oList)%2 == 1:
    print 'Odd number of controls selected, so *' + str(oList.pop()) + '* will be ignored.'


## List of Coordinates to deal with.
coords=["sclx","scly","sclz","rotx","roty","rotz","posx","posy","posz"]

ID=0
for i in xrange(len(oList)/2):
    mylist=[]
    invlist=["posx","roty","rotz"]  ## In this list you choose
    for coord in coords:   ## In this loop it will be decided which coordinates are flipped
        if coord in invlist:
            x=-1
        else:
            x=1
        mylist.append(app.GetValue( oList[ID]+".kine.local."+coord, "")*x) ## A List is built with the coordinate values and flips from the source Object. In XSI if I replace in this string 'local' with 'global' I can get a mirrot in world space instead of the local space.

    for coord in coords:
        app.SetValue(oList[ID+1]+".kine.local."+coord,mylist[coords.index(coord)],"")  ## List of values it's applied to the pair. Again I have 'local' in the string, but I could have 'global'.
