Highlight a point

[Technician13]

My webots's version is 2021a, my system is Ubuntu 18.04 , now I have got a destination point for my robot under world coordinate, what should I do to show this point in the simulation interface? For example, use a little green ball or litlle yellow cubic to make this point highlight. Thanks.

If you need it to change positions, the easiest approach is probably to add a Robot node with a Shape child and then pick whatever shape (Sphere, Box, etc) you like as geometry. Then you can use a supervisor to move the "robot" (the shape) around to whatever position you wish to and change its appearance (color) using also the supervisor functions.
