Rendering with constraints help!

I am a biomedical engineering grad and I’m using Blender 2.49 to animate a biomechanics model. I am sort of a noob in this so I apologise inb advance if I don’t manage to explain myself clearly. :o

In the first script I wrote, I had to attribute loc and rotation to several objects in the scene so I used:

obj = Object.Get(object_names[i])
                    obj.RotX = theta
                    obj.RotY = phi
                    obj.RotZ = psi

                    obj.LocY = -1*float(transf_list[12])
                    obj.LocX = float(transf_list[13])
                    obj.LocZ = float(transf_list[14])
                    Redraw()

Then, I added some bones with constraints to Copy Location and Rotation of these objects (empties) but when run the script they stay put instead of following the objects.
Does anyone know what lines I have to add to the code to make it work?

Thanks a lot:(

You have to have the script run every time the frame changes I think. This may mean you want to run it as a “scriptlink”, or as a script constraint… look into those

I added a Scene Scriptlink on Frame Change :

import Blender
arm=Blender.Object.Get('HumanRig')
Blender.Window.Redraw
Blender.Window.RedrawAll()
Blender.Scene.getCurrent().update()

but it disn’t solve the problem. Any clues?
