Set a curve in a script

Orikam

Hi everyone,

I set in a script to make a path with curve in space system, so i use the transform reference of a component mesh in space with GetTransformBySceneTimeLooped methods of a component curve in space but when i simulate the scene, nothing happens.
I do the same thing in editor, the component moves like it should do.
What i miss in my script to have the same result ?

Thanks for your help
