Crash when launching self-compiled simulator

[ZiwenWan]

Hi LGSVL team, I met some problems when I tried to simulate on a map built by my self. Here are what I did on my Windows machine:

• Pull the simulator code from GitHub and checkout to the release-20.06 branch
• Run the command 'git lfs pull'
• run 'npm install' for WebUI
• Open the project with Unity 2019.3.15f1
• Build the WebUI
• Build both the map and simulator (I built for both Linux and Windows) Here is my problem:
• The released binary can launch successfully on both windows and Linux, but the map generated can not be loaded successfully. I got the error message that the map can not be loaded.
• When I launched the self-built executable on Windows and Linux, the program will crash after showing the logo of Unity. I could not see the button "Open browser"
• Here is the player log when running the self-built executable on Windows:

Null Sensor Prefab Detected - Check RuntimeSettings SensorPrefabs List for missing Sensor Prefab

This is your issue. Find RuntimeSettings.asset in the editor Open SensorPrefabs list and make sure no sensors are null or missing. If you have created a new sensor in the simulator source code, be sure it is listed here. Let us know if you have any other issues.

[ZiwenWan]

Thanks for the answer. I followed your instruction and I found that element 21 (WheelControlSensor in your screenshot) in the runtime setting is missing. Can you provide more details about how to fix the missing sensor?

Also, I have not added any sensors. Do you have any idea of why this happens?

Thanks!

Unity can be a pain sometimes. I usually see this when I pull changes or switch branches while Unity is open. I try to always close unity when using git and open back up once I am finished. esp if you don't force compile with Ctrl+R. I always set unity to not recompile until I say. To fix, just drag the wheel control sensor prefab into the missing spot.

[ZiwenWan]

Thanks for the reply. I followed the instruction you gave:

• import the asset of wheelcontrolsensor
• Drag the prefab to the missing element Now, the crash problem has been fixed and the simulator can launch perfectly. I still met some problems when I tried to run the simulation with the map built locally.

Here is the snapshot of the error message:

And here is the log:

BTW, I think I executed the git pull command when the unity was still running. I was wondering whether you can provide more tips on how to recompile the project? I think that may help.

Thanks a lot!

[EricBoiseLGSVL]

Is the map scene file named SingleLaneRoadBicycle and the repo folder named SingleLaneRoadBicycle? See CubeTown:

Please open the bundle with any zip application and screen shot the contents

As for recompile, Edit -> Preferences -> General. I set Unity to false with Auto-Refresh (You then must use Ctrl + R and it will take a bit to get used to :) ) and always stop the editor when done running a test Also set Script Changes While Playing to Stop Playing and Recompile in General preferences. That way a recompile will stop playmode and prevent corrupted files.

[ZiwenWan]

SingleLaneRoadBicycle is just the nickname used in the simulator to refer to the map, right? I am not sure why I have to make the name consistent. The map scene file name and the asset bundle name are both "SingleLaneRoad". I used the project pulled from Github and just added another asset bundle into the map.

Here is the screenshot of the bundle:

Thanks!

[EricBoiseLGSVL]

If you are creating SingleLaneRoad, then keep this name. If you want a new one, make a new repo. You probable are having name conflicts with the map bundle being the same name. How are you adding another asset bundle into the map?

[ZiwenWan]

Here is a list of what I did to modify the map:

• Import an asset from asset store in Unity
• Directly drag the prefab into the map and adjust the position
• Rebuild the map I did not aim to build a new map. I just made some changes and rebuilt the single-lane road map. Thanks!

[EricBoiseLGSVL]

Do you have code components on the prefab you dragged in? Did you move the asset store assets into the folder for the environment repo?
