Hi all, Does anyone know what is the problem with using cygwin to compile Webots controllers (written in C) using Make? I receive the following message: make ...
... It is working fine on my machine. However, I have version 1.5.0_04 of Java. But I think this shouldn't be a problem as the Webots/lib/Controller.jar is...
Hi, i just updated Webots 5.0.8 on a machine and I get this message when I try to compile a controller (written in C) that I has been already using with Webots...
Hi, This is strange as it works fine for me (both with gcc and g++) under MinGW. Did you try to perform a make clean (i.e., remove the *.o files from your...
Just for future reference, it was a problem with my working directory(I didnt know what exactly was). What I did was to delete my working directory and start...
Hiya, Quick one this. I thought that the SUPERVISOR_FIELD_ROTATION_ANGLE returned a float of between zero and 2*Pi radians. For some reason my simulation...
Hi, have you tried this function in Webots 5.0.8? for some reason Webots crashes (after saving an empty jpg image) when I try to save images from the camera...
by the way, this is only trying to save using the jpg format, with png format works fine. Cheers, Edgar ... From: Edgar Bermúdez <edgar.bermudez@...> ...
... Yes, all values are allowed (0;2pi) and (-pi;pi) and we could imagine to have even higher values. This modification was introduced because of Servo and...
I have attached a file that is created when i run my experiments. I hope you could find what is happen with this information Thanks... ... From: Olivier Michel...
Hiya ... 5.0.8. Thanks for pointing this out! I have now got it sorted, though in my case (and in soccer_supervisor.c) it's the SUPERVISOR_FIELD_ROTATION_Y...
Hi, I just released Webots 5.0.9 which fixes a couple of bugs (and especially the hang bug under Windows after revert or load). You can download it from the...
hi can anyone tell me if the controllers for the supervisor and the robot are snyced? for example on each clock tick of simulation (return 64) does was one ...
hi everyone i have tried to test this by having both the supervisor and the robot controller print a count value to the log using robot_console_printf() just ...
Hi, About robot / supervisor synchronization, there is a field called synchronization in the CustomRobot, DifferentialWheels and Supervisor nodes. This field...
Hiya, I've been running long simulations with a genetic algorithm, and this error has come up a couple of times: "ODE Message 3: LCP internal error, s <= 0...
Well, you are entering the tricky parts of ODE... I believe these LCP internal errors are results of the accumulation of numerical errors due to extreme...
Hi, We recently found a bug in Webots 5.0.9, which disable the collision detection between robots. It is now fixed and we are going to release Webots 5.0.10...
Hello everyone, I would like to display some basic OpenGl graphics inside the webots scene, for example I would like to draw an ellipsoid given the center and...
... Yes, you will have to write a physics plugin (although it may contain no special physics programming), but it will contain a webots_physics_draw() function...
... Thank you very much! Do you know if (and where) I may find some sample code to get an example of initialization/finalization of the opengl state? On the...
... I have no example here (but maybe other users can share some sample code on this). Basically, you should use the push/pop mechanism of OpengGL state with...
Dear Olivier, I'm sorry to bother you, but today it seems that my QI has run out !! :) I was playing with the "sample.c" inside the physics directory, but I ...
Hello everyone, I'm running a simulation where I use the OpenGl libraries to draw objects (lines, ellipses, cubes, ...) in the scene. The drawing code is...
Paolo, You should set glMaterial() before using glColor3f(). By the way, did you succeed to compile the DLL with Visual C++ ? By default we only support MingGW...
Hello Matthew, Unfortunately the linear servo have not been included in Webots 5.0.9. I'm personally developing the linear servos, and spring & damper for...
Dear Olivier, thank you very much for your hint, with this simple code: glEnable(GL_COLOR_MATERIAL); glColorMaterial(GL_FRONT_AND_BACK, GL_DIFFUSE); //can also...
Hi, A new release of Webots is available. It is an emergency release for Webots 5.0.9 as it fixes a few important bugs introduced in Webots 5.0.9 (like ghost...
