Bug report

• UE/Unity version: UE5.1
• autopilot version: NA
• OS Version: Windows 10

What's the issue you encountered?

I cannot build AirSim for UE5.1 in CitySample.

How can the issue be reproduced?

I downloaded the repo and switch to commit b415b39. Used the build.cmd with CMD for VS2022 and copied the folder of the plugin to AirSim. Modified the DefaultGame.ini file and generated the Solution Project. Compiled with F5 and no luck.

Hey,

Thanks for checking my branch out and filling the issue. It looks to me that I have added support for UE 5.1 (and newer CitySample compatible with UE 5.1) later than the commit you have pointed. At your commit, 5.0 was supported and 5.1 was added bit later with 219b0bc

The errors you pasted above suggest that there is some section of Airsim car pawn that is not compiling. As I am only using computer vision mode, what I have done is completely disable car pawn code just to make it compiling. This particular error should be fixed in the newer version of my branch - pls let me know. The one you have pointed out is really old.

I would strongly reccommend to stick with the newest commit, should be less buggy, more stable and the latest one are compatible with upcoming UE 5.2 (new instructions are in a readme).

Also please note that there are two Citysample versions currently on epic marketplace. You should go with it like that:

• citysample 5.1 for UE 5.1 or UE 5.2 (ue5-main commit I've pointed in readme) and latest commits in my citysample branch
• citysample 5.0 for UE 5.0 (I worked with it in the past, didnt check compatibility for my recent commits)
