I try to use ADetourCrowdAIController, but it gives linking errors:
Header file:
include “DetourCrowdAIController.h”

In your Build.cs file add AIModule to the PublicDependencyModuleNames array.

It was already added, i fixed the linking errors by doing this:
class POSSESSIONGAME_API AEnemyAIController : public AAIController
instead of ADetourCrowdAIController i inherited from AAIController.

Ah that’s correct, and to get the crowd component you do this in your constructor

AKaiAIController::AKaiAIController(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer.SetDefaultSubobjectClass<UCrowdFollowingComponent>(TEXT("PathFollowingComponent")))
{
	
}
