Move AI Character using C++ instead of blueprint

simtbi, thank you for you attention to my question!
I had all the needed includes and that’s why I was so frustrated. But! At last I found out what was missing - it was the dependency in MyGame.Build.cs file.

PublicDependencyModuleNames.AddRange(new string] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay", "AIModule" });

it was this line, where I had to add AIModule!
I guess I have to dig deeper into this, and mind dependencies next time something wouldn’t compile.

Ahh yes, that was going to be my next suggestion Glad you got it sorted anyway

So now, my code looks like:

	
        // spawns default controller (if not, there is no controller for NPC to control)
	NPC->SpawnDefaultController();

	// cast controller recieved in NCP in Bar Class, derived from AAIController class
	ABarNPCAIController * moveController = Cast<ABarNPCAIController>(NPC->GetController());

	// moves character to location defined by TargetLocation component of moveEvent	
	moveController->MoveToLocation(*moveEvent.targetLocation);	

still need some tuning, but it works!
As you, or anybody who have same problem might notice, I had to create my own AIController class (I called it ABarNPCAIController), which striclty inherits from AAIController, because engine demans my main Game.h file to be included in all of .cpp’s and if I just left default AAIController, I would have to include it in AIController.cpp.

Hmm, that doesn’t sound right, you should be able to use AAIController directly just fine (assuming that does everything you need).

I have the following code in one my game classes and it works no problem. Are you getting a specific error if you use AAIController directly?

UNavigationPath* path = UNavigationSystem::FindPathToLocationSynchronously(this, a->GetActorLocation(), dest, a);

if (path && path->IsValid())
{
	FAIMoveRequest req;
	req.SetAcceptanceRadius(50);
	req.SetUsePathfinding(true);

	AAIController* ai = Cast<AAIController>(a->GetController());
	if (ai)
	{
		ai->RequestMove(req, path->GetPath());
	}
}
