Using Run Time Selection : table pointer error at run time
Hi
I attempt to write a custom solid body motion solver. The external force management is massively inspired from "sixDoFRigidBodyMotion" (many thanks to the author), and uses the Run Time Selection mechanism.
The problem is that the RTS table pointer is not found and throw an error at run time.
Here's the skeleton of my code and the run error message.
I've been struggling with that bug for days.
I probably miss something big, too big to be seen ?
Dear RTS specialists, I would appreciate your help so much
