Hello and thanks dmon shelton,
I tried this but still nothing :(
frameStart = 1
frameStop = 50
step = 1
myObject = cmds.ls(selection = True)
#This loop queries the position of the animated object and creates a curve
based on its position.
for object in myObject:
i = frameStart
while i <=frameStop:
#yield i
i += step
print('The current frame is', cmds.currentTime( i, edit = True))
animationCurve = cmds.curve( p = [(0,0,0)], name = ('Jack_' + str(object) ))
time = cmds.currentTime(i, edit = True)
#Get the object position on everyFrame.
pos = cmds.xform((object), r=True, query = True, t=True )
cmds.curve(animationCurve, append = True, p = (pos))
