I’m trying to use some of the new AI logic that is being released in 4.7 so I decided to convert my game. When I do so it fails to compile but it’s not my code that’s throwing the errors.

I’m not entirely sure what would be causing this. I’ve tried a clean build and still get the same errors. I’ll continue to debug and post additional details as I get more information.

REPO STEPS

  1. Create a new top down project

  2. Add an AIController to the code. (this compiles fine)

  3. Setup the AIController for detour using the code bellow

  4. Add the required header #include “Navigation/CrowdFollowingComponent.h”

  5. Compile fails.

    #include “MyProject.h”

    #include “Navigation/CrowdFollowingComponent.h”

    #include “MyNewAIController.h”

    AMyNewAIController::AMyNewAIController(const class FPostConstructInitializeProperties& PCIP)
    : Super(PCIP.SetDefaultSubobjectClass(TEXT(“PathFollowingComponent”)))
    {

    }

Thanks for reporting it. I’ve just fixed it in our 4.7 sources and it will be included in 4.7 p3, but for now just add this line

#include "AITypes.h"

just after #pragma once in CrowdAgentInterface.h

Cheers,
