ATriggerVolume Issue

[Larion]

Hey Guys,
I would really appreciate it if you could help me out.

So I’m having this weird issue with my ATriggerVolume:

This is my code:

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

#include "CoreMinimal.h"
#include "Components/ActorComponent.h"
#include "Engine/TriggerVolume.h"
#include "OpenDoor.generated.h"


UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
class ESCAPEROOM_API UOpenDoor : public UActorComponent
{
	GENERATED_BODY()

public:	
	// Sets default values for this component's properties
	UOpenDoor();

protected:
	// Called when the game starts
	virtual void BeginPlay() override;

public:	
	// Called every frame
	virtual void TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;
	void OpenDoor(float DeltaTime);
	void CloseDoor(float DeltaTime);

private:

float InitialYaw;
float CurrentYaw;

UPROPERTY(EditAnywhere)
float TargetYaw = 90.f;

float DoorLastOpened = 0.f;

UPROPERTY(EditAnywhere)
float DoorCloseDelay = 2.f;

UPROPERTY(EditAnywhere)
float DoorOpenSpeed = 1.f;

UPROPERTY(EditAnywhere)
float DoorCloseSpeed = 1.f;

UPROPERTY(EditAnywhere)
ATriggerVolume* PressurePlate;

UPROPERTY(EditAnywhere)
AActor* ActorThatOpens;
		
};

I tried changing the order of the includes, any other ideas for this error?

Thanks!

Solved by including #include “Engine/Engine.h” which isn’t mentioned anywhere, but nice challenge!
