Using UE 5.5.3 + Colosseum (Airsim)

[hamedbastami]

Bug report

• AirSim Version/#Colosseum :
• UE/Unity version: 5.5.3
• autopilot version: --
• OS Version:--

What's the issue you encountered?

I installed the Colosseum version of AirSim on Unreal Engine 5.3.5 and created a new project. I also cloned the source code using the following command:
git clone --recurse-submodules https://github.com/CodexLabsLLC/Colosseum.git
However, when I try to open the project, I get the following error:

">"Project Name" could not be compiled. Try rebuilding from source manually."

I have already completed the following steps:
✅ Installed Visual Studio 2022
✅ Created a Plugins folder in my project and copied the AirSim plugin inside
✅ Cloned the Colosseum source using Git
✅ Tried opening the project in Unreal Engine 5.3.5, but it failed

How can I fix this issue? Any help would be greatly appreciated! 🚀

I've encountered this issue a lot. If you've already run the build.cmd script and compiled the plugin, I would generate a visual studio project file from the unreal engine project and just attempt to build the project in there. You can more easily tell what the actual issue is in the compilation process is and maybe fix it from there.

I often encounter this issue as well, but it's on Ubuntu. For your problem, first, after moving the AirSim plugin to the Plugins folder, please check if it is enabled in the uproject file:

{
  "Name": "AirSim",
  "Enabled": true
}

Then, delete the compilation cache folders: Binary, Intermediate, and Saved.
Next, manually invoke the command-line build:
./Engine/Build/BatchFiles/Linux/Build.sh <Project Name> Linux Development <path_to_uproject_file>
You might encounter a prompt saying there are different compiled versions of the AirSim plugin. If so, choose to recompile, and then proceed with the build.
This approach seems to work.
