Re: Turn off update checker, interferes with automated sim runs

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, at the bott...

Turn off update checker, interferes with automated sim runs

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...

Re: V-REP from command line, press the "hare" button

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

Re: V-REP from command line, press the "hare" button

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.

V-REP from command line, press the "hare" button

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...

Re: How to enhance the speed of simulation

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 ...

Re: Learning joint dynamics

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...

Re: Mixed controller, C and lua

That would let me call a C function from lua then, but when my C function is acting as the main part of a robot's controller code, and needs things like static variables which preserve across subsequent times the code is run, would I have problems? Does using this plugin method effectively start a w...

Re: Mixed controller, C and lua

Thanks for the plugins tip, can you point me to a clear example where this method is used to allow a segment (the bit that handles the logic and "thinking") of a child script to use C while the rest (the bits of script dealing with reading sensors and writing to actuators and custom datablocks) uses...

Re: Mixed controller, C and lua

When running the sims I don't want to run them on my actual robot and have it try to connect to a computer which has V-REP on it, the robot's hardware isn't too fast and wouldn't cope with this. Furthermore my work is with swarms of robots, so I need each to be able to run a V-REP child script of it...
