AAIController::SetPathFollowingComponent

function AIModule Blueprint Since 4.0

#include "AIController.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Replaces the active PathFollowingComponent with a different one. Intended for initialization and setup — not for hot-swapping during active movement.

Caveats & Gotchas

• The header comment explicitly states this does not transfer path following state. Call it only during initialization or setup, never while a move is in progress.
• Passing nullptr will leave the controller without a path following component, causing GetMoveStatus, MoveToActor, and related functions to silently do nothing or return stale results.

Signature

void SetPathFollowingComponent(UPathFollowingComponent* NewPFComponent)

Parameters

Example

{
	UMyPathFollowingComponent* CustomPFC =
		CreateDefaultSubobject<UMyPathFollowingComponent>(TEXT("MyPFC"));
	SetPathFollowingComponent(CustomPFC);
}
