CarSim manual control example not working

[svanimisetti]

I am unable to use CarSim plugin example in CARLA as per instructions in the documentation. The following information should help reproduce the issue.

CARLA version: 0.9.13 Platform/OS: Windows 10 Problem you have experienced: manual_control_carsim.py does not use CarSim vehicle model physics What you expected to happen: CARLA to use CarSim model for physics - but it does not.

Steps to reproduce:

1. Download latest version of CARLA and install to C:\CARLA
2. CarSim program installed to C:\CarSim2021p1_prog. Open program and export UE4 example (Run Control dataset -> External Control, Wrapper -> Unreal Engine 4 Plug-in, Lead Vehicle) to C:\CarSim2021p1_data\ue4simfile.sim
3. Start CarSim GUI or license server using C:\CarSim2021p1\Programs\cs-lm-cli.exe to acquire solver license.
4. Download CarSim UE4 plugin v2021.1 r166435 from MSC website and unzip the contents to C:\CARLA\CarlaUE4\Plugins\CarSim
5. Start CARLA server using cd C:\CARLA && CarlaUE4.exe -windowed -carla-server -carla-no-networking -quality-level=Low
6. Modify line 419 in manual_control_carsim.py to:

world.player.enable_carsim("C:/CarSim2021p1_data/ue4simfile.sim")

7. Start CarSim example provided with CARLA installation using cd C:\apps\CARLA\PythonAPI\examples && python manual_control_carsim.py
8. The pygame console starts - and I can control the vehicle. Press k to switch to CarSim solver as per python code (line 419). However, I think CarSim solver is never used, as the solver output and log files are not being written to the CarSim results folder for this testrun (C:\CarSim2021p1_data\Results\Run_dd7a828d-4b14-4c77-9d09-1974401d6b25)

Do I need to compile CARLA from source on my computer to be able to run the CarSim example? This is not clearly mentioned in the documentation. If re-compilation is not needed, it would be helpful if the steps to install the CarSim plugin into CARLA installation are clearly explained.

Hello, I have same problem, too.

When I print the output of world.player.enable_carsim("C:/CarSim2021p1_data/ue4simfile.sim") after modifying the line 419 in 'manual_control_carsim.py', the output is Nonetype.

Can you solve that problem??

Hello, I had a similar experiance of crash in carsim plugin using carla 0.9.13 compiled from source and CarSim_UE4.26_Plugin_v2021.0.0_2020-12-14_r153946.zip with the sim file provided at VehicleSim_Plugin-Example-4.26_Project-r154045.zip I could see carla output saying loading library and immediately saying releasing library :

Loading simfile: .../ue4simfile.sim Loading library: /tmp/VSSuxK9E7 Releasing library

Did anyone have a working experiance of carla + carsim on ubuntu 18.04?

hi, i'm using Linux version of both and Carsim not working either. On your procedure 8, you mentioned pressed k, did you try to press CTRL + k? Because in the script it says "event.key == K_k and (pygame.key.get_mods() & KMOD_CTRL)"
