that’s why I gave a link only to physical constraints, in version 0.3.0 you can do this using the bpy module, in versions 0.2.5 you can use only physical constraints (dynamic and rigid bodies) or use bone actuators for which you can create connections again at the expense of Physics Constraints (bge.constraints) but you will not create restrictions inside a specific dice during the execution of the game and you can only get what has already been created as in this topic by bge [help][bge] set bone location - #21 by winspeednl
