From https://chipmunk-physics.net/forum/viewtopic.php?t=2338 and the chipmunk author: Chipmunk doesn't have any global shared state. You can safely run separate Chipmunk spaces in different threads. It's not thread safe however. If you want to access a single space from multiple threads, you'll need...

Sure--pm me with some times that work for you and we can find a time to chat.

Hello, ARGoS crashes whenever I try to use the spatial_hash capability of the dynamics2d engine with multiple engines. If I set two physics engines (each has half the arena) and then 2 threads, ARGoS always crashes. If I then set ARGoS to only use 1 thread (keeping multiple physics engines), then th...

Specifying the light placements manually helped to some degree. Now, I only see that black floor sporadically (see attached video). If I disable interpolation it happens less, but it still happens. The blocks on the floor (black squares in the video) also seem to sporadically move around, which does...

I think your best bet is to contact the Thymio extension author and ask for a Thymio example written in ASEBA. ARGoS only supports controllers written in C/C++ or Lua. From looking tho extension repo, I don't see anything that is not written in C++ :-(, so it may be that the documentation is incorre...

Yeah I did try that. The default ARGoS camera positions were a little low for what I wanted, so I raised them up to ~10 meters above the arena. Instead of the entire floor being black, only MOST of it was--the end of the arena furthest from the lights had a white floor, and I was able to determine t...

Upon further investigation, I found that the black floor was caused by having lights that are too high above the floor/too bright. Why would this be the case ?

Do you have Qt installed ? It looks like libQt5Core.so is missing. What does "ldd /path/to/argos3/lib/libargos3plugin_simulator_epuck.so" show ?

Did you install ARGoS from source or from a package ? It looks like ARGOS can't find all its libraries. Does the <install prefix>/lib/argos3 contain the epuck library ?

Have you made any headway on this issue ?
