When I try to make a build, I'm getting error
Cannot open include file: 'Actions/PawnAction.h': No such file or directory
But I have this file in Visual Studio
You need to include AIModule
in your module dependencies.
Source: JamieDale from UE4 Q&A site:
Right, so if your game was called "MyGame", then you'd have a file called "MyGame.Build.cs" inside the "Source\MyGame" folder.
This file tells the UnrealBuildTool (UBT) what to do when building your game.
In there you should see an array for PrivateDependencyModuleNames and/or PublicDependencyModuleNames - this tells UBT which modules need to be linked when building your game, so you'll need to add "AIModule" to one of those.
