Hello Matej, ... Yes and no, if you prefer to use the C headers, it's fine but you need to add the line to your Makefile. ... The default is to use the C...
Hello Sridhar, Webots uses two different time steps: the "physics step" and the "control step". The "physics step" is the time interval between two calculation...

Hello Vinod, This is not exactly correct. You always need to have a call to wb_robot_step() in you main loop. This is necessary to return the control flow to...
Hi, Its not the problem of shadow. I also checked by setting the castShadow to false but it didn't work. I am attaching a screenshot and also .wbt file along...
