Hello,

Ubuntu 20.04

Matlab 2022b

I am getting started with the Roadrunner toolbox and integrating with Simulink. I have a roadrunner scenario and I would like to read the ego vehicle poses. I am following this guide but making my own simulator: https://www.mathworks.com/help/driving/ug/highway-lane-change-planner-with-roadrunner-scenario.html

I have an ego vehicle defined with ID 1 in my scenario.

However, on Simulink the roadrunner reader block (block at the bottom of screenshot) throws an error saying "actor with the given id ' ' is not defined". What should I do to fix this issue?

Hi Giancarlo,

I understand that you are facing an issue with the “RoadRunner Scenario Reader block”. To receive and process the actions or events from “RoadRunner Scenario” in Simulink, you must create a Bus Object and add it to the “RoadRunner Scenario” Block.

Please refer to the following documentation for further information,

Hope this helps!
