Stop Foot Sliding With MotionBuilder and Python

Update

Oct. 29 2018 –

For the script to work in MotionBuilder 2018 I had to make a slight change. You can down load a new version of StopFootSliding here, I also made the changes to the script below in the original post.

The only difference between to last release and this one is that I removed an FBContainer, which was just a visual element and had no functional baring on the tool. The attribute FBContainer is no longer supported in MotionBuilder 2018, The new version is FBVisualContainer().

StopFootSliding v1.0 was giving this error in MotionBuilder 2018:

“cInfo = fb.FBContainer() AttributeError: ‘module’ object has no attribute ‘FBContainer'”.

Thanks Andy.HH for bringing this to my attention.

After exploring FBVector3d() and creating the Animated Align post, I started to think “Hey, why not use that same process and stop a foot from sliding!”. Using a reference frame we can grab the translation and rotation of an object and then over a range of time have that object match it referenced translations. I decided to work with layers when preventing foot sliding as to not destroy the original data.

Here is a quick demo of the tool (sorry for the poor audio).

You can down load the “StopFoorSliding” tool here.

Here is the script with my notes:

import pyfbsdk as fb
import pyfbsdk_additions as fba

    Frame = fb.FBSystem().LocalTime.GetFrame()
    return Frame

    fb.FBPlayerControl().Goto(t)

##Check For Conflicts In User's Desired Frame Ranges

        return False

    lCount = fb.FBSystem().CurrentTake.GetLayerCount()
    ##Name the Layer to be "Selected Object Name: Start Frame to End Frame" (ie. LeftHeelPivot: 100-150)
