Realtime Spring , a similar tool in 3ds max developed by Harrison Yu .

How to Use: Drag the "RealTimeSpring/scripts/RealTimeSpring.mel" into maya or make button of it.

UI is written in .net ( the installer will automatically copy "clr.pyd" and "Python.Runtime.dll" into maya script folder .

Fixed problem : forgot to upload Python.Runtime.dll .

if you want to compile your own python pyd corrisponding to older maya version , please go to https://github.com/pythonnet/pythonnet. in project setting change the python version . i.e. PYTHON2_4 )

This script require the mll plug in the MXSController folder ( the folder also contains source code ). the plug in simulate the max script controller does , which evaluate python code each system tick no matter user or time changes any value .

Another good example of this node. http://youtu.be/fTnOzDko0TY

I can set python expression directly on the wheel to make it point to the moving direction.

Note . this script system not been massively test . may cause problem during network render . please use it at your own risk .
