Player Vehicle and Non-player Agents Not visible #684

Closed ptiwari0664 closed 6 years ago

ptiwari0664 commented 6 years ago

Hello all,

I am a newbie in carla simulator. I have build carla from the source and also able to make binary out of it.

Platform: Ubuntu 16.04 LTS CMAKE version: 3.12.0 ROS Version: Kinetic

Problem: While executing the command "make launch", Unreal Engine's Editor launches and I am able to see town01 in it. However, player vehicle and other cars and pedestrians are not visible.

Query 1: Does anyone has a solution of it or knows how can i import player vehicle and non-player agents?? Query 2: How can i add already defined vehicle in the map (like tesla or mustang or truck)?? I will be glad to receive any help. Thanks in advance.

Hi @ptiwari0664,

  1. If you want to use the ros-bridge, it only works for CARLA 0.8.X (see here https://github.com/carla-simulator/carla/issues/325#issuecomment-414575177)

  2. Looks like you are using the 0.9.X version of CARLA. If so, what you got is what you supposed to get. Take a look at this issue #660. Also more information about the 0.9.0 here

Cheers.

hi Marc,

Thanks for replying. I checked the reference which you gave. Yes, I am using 0.9.x version, however it seems, this version is not going to work for me as the ROS support is not there.

Thanks.

Anyone know what the default CARLA driver model (e.g. car-following, lane-change modeling) is based on? Are the non-player agents/vehicles based on say the Intelligent Driver Model (IDM) or Optimal Velocity Model (OVM) for car-following model? Could not track down any document explicitly describing what the AI non-player vehicles model is modeled after. Any information that can be provided is greatly appreciated.
