Re: coppeliaSim crash problem

It seems that CoppeliaSim requires a X11 server even when run in headless mode. That's why it is suggested to use X11 forwarding (i.e. ssh -X or ssh -Y ). In fact, when run via ssh with X11 forwarding, it would work only in headless mode. OpenGL would fail to init otherwise. Additionally, if your lo...

I have updated the libPlugin folder in CoppeliaSim with the latest commit.
It appears you didn't.

Re: libsimExtROS2Interface builds but doesn't load

You need to source the ROS2 environment (source /opt/ros/foxy/setup.bash) prior to running ./coppeliaSim.sh in the same terminal.

Re: How to set the color of multiple shapes at once?

Hi,

you can use sim.getObjectChild (or alternatively sim.getObjectsInTree) to retrieve an object's children, and you can set the shape color of every children with a for loop.

Hi, when using multiple goal states, the search will stop as soon as one goal is reached. Which one is not known, but you should be able to easily check. I didn't find much documentation of ompl::base::GoalStates class, but as you can see from how distanceGoal is implemented, it will return the dist...
