Hello,

it seems you are trying to use the old, deprecated remote API. Make sure to use the ZeroMQ remote APi, which is faster, more flexible, and simpler to use.

Cheers

Hello,

please do not use the legacy remote API anymore. Instead, use the ZeroMQ remote API, which is more flexible, complete, and faster.

To retrieve the handle of an object via the ZeroMQ remote API, do this:

Hello, have a look at following functions for example: sim.createPrimitiveShape sim.createMeshShape sim.loadModel sim.setObjectInt32Param(shapeHandle, sim.shapeintparam_respondable, respondable) sim.setObjectInt32Param(shapeHandle, sim.shapeintparam_static, static) sim.setShapeMass sim.setShapeInert...

Hello,

the error very probably happens because the signal is not set (yet), and the call to sim.getFloatSignal returns nothing. So you can't assign nothing to a variable in MATLAB. Use a try-catch block to handle a possibly non-existing return value.

Hello, yes, it is normal that the display is black, since you disabled rendering with: sim.setBoolParam(sim.boolparam_display_enabled, False) Disabling rendering will not disable vision sensors that will still be able to function normally. Instead of sim.getVisionSensorCharImage, use sim.getVisionSe...

Hello,

it seems that Windows is now handling console windows in a grouped fashion, and you cannot directly hide individual consoles anymore: those consoles will simply be minimized, not hidden. This now also happens with older CoppeliaSim releases (on Windows 11).

Hello, this is an undocumented feature. Use following to get inspiration: --lua sim = require'sim' function sysCall_thread() while true do -- Read the keyboard messages (make sure the focus is on the main window, scene view): local msg, auxData = sim.getSimulatorMessage() if msg ~= -1 then if msg ==...

Hello,

thanks for the mention, yes, we are aware of that and it should be fixed for next release (in 2-4 weeks).

Hello, best would be to post a minimalistic, self-containing scene, that illustrates your problem. Not sure what object you use to get the robot's position/orientation, but if you use the robot's base, then indeed you can only look at the gamma component of the orientation. Keep in mind that it vari...
