Re: Signal 11 error on linux Mint MATE 19

I think Mint 19 is Ubuntu 18.04 based, so that would explain my trouble. I'd give a good guess that if V-REP ran on ubuntu 18.04 it would probably cope on Mint 19 to (they are very smilar distros). Do you expect V-REP 3.6 to be ubuntu 18.04 compatible? As well as preserving compatibility with Ubuntu...

Re: Signal 11 error on linux Mint MATE 19

EDIT: I've tried V-REP 3.4.0 (previous version) on this PC, it opens up alright and runs a few simple simulations ok. This issue is clearly related to a change made to V-REP between version 3.4.0 and version 3.5.0*. As all my files I need to work on here made in 3.5 though i get serialisation warnin...

Signal 11 error on linux Mint MATE 19

I've got linux mint mate 19 newly installed on a PC and have tried to install V-REP. It crashes upon startup and prints the below error message into the terminal. robert@robert-HP-PC:~/V-REP_PRO_EDU_V3_5_0_Linux$ ./vrep.sh Using the default Lua library. Loaded the video compression library. Add-on s...

Re: Repeatable seeded pseudorandomness

Just to check, will there be a way to set a seed for the whole scene, then even if multiple identical robots are all running the same controller they won't all get the same sequence of random numbers? Will there also be other options to have a separate randomness source and separate randomseed on ea...

Re: Repeatable seeded pseudorandomness

Thank you for that, any idea when the new version of V-REP with this feature will be released? P.S. I'm assuming you'll do all you can to maintain compatibility of scripts and models between the current version and that next one. I'd hate to have to redefine all my geometry, actuators and custom sen...

Repeatable seeded pseudorandomness

If one wants to insert deliberate randomness into a simulation using (for example) CompassAngleToDriveAlong=math.random(-180,180) but one wants the series of directions chosen by this function to be random but repeatable then in lua one would typically set math.randomseed(KnownConstantValue) beforeh...

Re: Are proximity sensors actually line of sight?

I'm pretty sure the model between the dummy and sensor is detectable, yet the sim.checkProximitySensor(thisSensor,thatDummy) command still seems to see the dummy.

Re: Nested joints: how to associate both a prismatic and a revolute joint to an object

You can make the object to go between the joints visually invisible and dynamically non-respondable. You still need to give it a mass and moments of inertia but otherwise it can bne like its not there at all. The joints can be co-located in space, an object can go between things in a hierachy withou...

Are proximity sensors actually line of sight?

Excuse me, I've got some child script code running on a proximity sensor in an attempt to check whether a dummy object is within it's field of view. The key line in the child script being InFieldOfView, junkDistance, RelativePos=sim.checkProximitySensor(ThisSensor,thatDummy) If InFieldOfView==1 I th...

Change volume colour of proximity sensor from script

Through the GUI one can click on a proximity sensor in the hierachy, then "adjust volume colour" in the "scene object properties" dialog box, then change things like ambient colour or visual pulsation frequency. Is there any way to do this from within a child script, I'm using proximity sensor to se...
