Seeding CoppeliaSim

[arennuit]

Dear all,

We would like to use CoppeliaSim within the scope of a features tests framework (same as a unit test framework : we compile our control / behavior code, run it against CoppeliaSim for simulation and check we end up with the same behavior as before - so we can track unexpected behavior changes).

We have noticed that CoppeliaSim's behavior is not fully deterministic (there must be some calls to randomization functions). Hence the simulation results we get are each time slightly different. Is there a way to make CoppeliaSim deterministic?

Thanks!

Hello,

except for what the physics engines do, things should be pretty deterministic in CoppeliaSim. Try switching to another engine to see if the problem persists.
Physics engines sometimes introduce randomness in order to obtain better results on average, and/or smooth results.

Cheers
