this is one Which other do you want :slight_smile:

#4

this is the Mover code `// Fill out your copyright notice in the Description page of Project Settings.

#include "Mover.h"
#include "Math/UnrealMathUtility.h"


// Sets default values for this component's properties
UMover::UMover()
{
	// Set this component to be initialized when the game starts, and to be ticked every frame.  You can turn these features
	// off to improve performance if you don't need them.
	PrimaryComponentTick.bCanEverTick = true;

	// ...
}
 

// Called when the game starts
void UMover::BeginPlay()
{
	Super::BeginPlay();

	OriginalLocation = GetOwner()->GetActorLocation();
	// ...
	
}


// Called every frame
void UMover::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
	Super::TickComponent(DeltaTime, TickType, ThisTickFunction);

	


	if (ShouldMove)
	{
	FVector CurrentLocation = GetOwner()->GetActorLocation();
	FVector TargetLocation = OriginalLocation + MoveOffset;
	float Speed = FVector::Distance(OriginalLocation, TargetLocation) / MoveTime;

	FVector NewLocation = FMath::VInterpConstantTo(CurrentLocation, TargetLocation, DeltaTime, Speed);
	GetOwner()->SetActorLocation(NewLocation);
	}
	

	// ...
}

void UMover::SetShouldMove(bool NewShouldMove)
{
	ShouldMove = NewShouldMove;

}

and this is Grabber Code

	// ...
}


// Called when the game starts

// Called every frame

	if (HasHit)

	}
	
}


UPhysicsHandleComponent* UGrabber::GetPhysicsHandle() const
{
	return GetOwner()->FindComponentByClass<UPhysicsHandleComponent>();

bool UGrabber::GetGrabbableInReach(FHitResult& OutHitResult) const

	return GetWorld()->SweepSingleByChannel(
		OutHitResult,
		Start, End, 
		FQuat::Identity,
		ECC_GameTraceChannel2,
		Sphere
	);
	
	
}
`
and this is Trigger Code `// Fill out your copyright notice in the Description page of Project Settings.


#include "TriggerComponent.h"





UTriggerComponent::UTriggerComponent()
{
    PrimaryComponentTick.bCanEverTick = true;
}

void UTriggerComponent::BeginPlay()

    Super::BeginPlay();
}

AActor* UTriggerComponent::GetAcceptableActor() const
{
    TArray<AActor*> Actors;
    GetOverlappingActors(Actors);
     
    for (AActor* Actor : Actors)
    {
        if (Actor->ActorHasTag(AcceptableActorTag))

            return Actor;

    if(Actor !=nullptr)
    {
        Mover->SetShouldMove(true);

    }
    else
    {
        Mover->SetShouldMove(false);
    }
}

void UTriggerComponent::SetMover(UMover* NewMover)
{
    Mover = NewMover;

}
#5

I also Tried to Debug using UE_Log it is Setting it to true But Not working
image it is also setting it to true but its just dont want to move

#6

And the trigger and the tags on the actors?
