### GetWorldLinearVel animation problem

Hello everybody,

I am moving a box using the animation system (KeyFrame,...). I would like to output some datas like the model's position and speed. I have created a model plugin.

No problem for the position but I have some trouble for the speed.

The GetWorldLinearVel function seems to return a 0.0 value for x, y and z attributes.

Here is the code to get the speed datas :

custom_msgs::msg_command speed_msg;
