The default khepera K3 model includes in v-rep 3.5 includes a UI which when thr robot is clicked upo9n will appear but if the robot, during the simulation run, doesn't get selected stays invisible. How is this done? I want to do something similar for models of my own but all I can see within the khe...

Thanks fferri, that looks like an appropriate solution for my trouble. I've edited doNotShowUpdateCheckMessage in the usrset.txt file from false to true but can't find "suppressStartupDialogs = false" anywhere so as to change it to being true, should I just add that line in, set to true, a...

I need to turn off the automatic update checker as it is causing havoc with my attempts to run sims over nights and weekends. After setting a series of simulations running using (on a linux terminal) for i in {1..20}; do ../vrep.sh -g70.5 '/home/user/Downloads/V-REP_PRO_EDU_V3_5_0_Linux/scenes/filen...

Thanks, that sim.setInt32Parameter(sim.intparam_speedmodifier,x) tip is exactly what I needed.

The floatparam option isn't much help to me. I'm not looking to decrease the number of simulation ticks per second of sim time, I just want to do what the "hare" button does and only render a frame on a smaller fraction of those ticks.

On linux I can run V-REP from the command line using things like ../vrep.sh -g10 '/home/full/file/path/file.ttt' -s10000 -q to launch a sim which will run until 10 seconds of sim time has elapsed which quits V-REP when the sim ends, with a parameter of 10 fed in as first argument. But once running I...

Simulation itself can be made faster by using the simplified shapes to build up your physics engine enabled structures, avoiding meshes where possible and especially avoiding concave objects. You can use compounds of simple shapes to form your parts. If you disable any un-necessary proximity sensor ...

You can replace a joint object's callback script with something else, and you can then feed data to the joint object from another object by using something like a custom datablock. But I can't imagine why you would want to replace the simplicity of a deterministically commanded joint with a neural n...

Thanks, all woking well now. Am passing data into the joint object via a custom datablock, I have set things up so the datablock gets set by the script of the robot's body during the actuation simulation step. Then in the simulation's sensing step the joint object reads the custom datablock and upda...

This seems fixed in version 3.6, the Ubuntu 18.04 edition. Downloaded a copy a few minute ago, first time I tried to do "./vrep.sh" I got a signal 11 error again, but there was a helpful print statement just beforehand advising me to run "sudo apt install libgl1-mesa-dev". I inst...
