i have a problem. In tutorial you have said, "Note that each dot (.) can be substituted by any number of named or unnamed nodes". But if I use dWebotsGetBodyFromDEF(defname.), I can only get GeomID from one unnamed nodes, not all nodes. What should I do, if I want to get GeomID frome all unnamed subnodes.

Best wishes, Thomas

  • In its current form this question can't be answered. What tutorial are you referring to? What program/library? What version of what software (ROS?). – cst0 Dec 08 '23 at 03:30
  • with webots R2023b and ROS1. https://cyberbotics.com/doc/reference/utility-functions. It is for collision detection used physics plugin. I can only get the GeomID from first subnodes, not all. – Haolei Tong Dec 08 '23 at 10:17
