Problem

I have created a pawn wich is controlled by a custom player controller. At the moment I move the pawn like this:

FVector NewLocation = GetActorLocation();
NewLocation += GetActorForwardVector() * (SpeedLvL * Speed) * DeltaTime;
SetActorLocation(NewLocation);

This part is exectuted every Tick. But when I move my pawn like this it obviously “ignors” collision.

So I’ve implemeted a PawnMovementComponent by following this documentation (Step 2 & 3):

In the documenation the Input is passed to the MovementComponent like this:

void ACollidingPawn::MoveForward(float AxisValue)
    {
        if (OurMovementComponent && (OurMovementComponent->UpdatedComponent == RootComponent))
        {
            OurMovementComponent->AddInputVector(GetActorForwardVector() * AxisValue);
        }
    }

After I’ve followed this steps and wanted to test my code the if statement doesn’t become true. Splitting it into:

void ACollidingPawn::MoveForward(float AxisValue)
	{
		if (OurMovementComponent)
		{
			GEngine->AddOnScreenDebugMessage(0, 5.f, FColor::Yellow, "Step 1 done");

			if (OurMovementComponent->UpdatedComponent == RootComponent)
			{
				GEngine->AddOnScreenDebugMessage(0, 5.f, FColor::Yellow, "Step 2 done");

				OurMovementComponent->AddInputVector(GetActorForwardVector() * AxisValue);
			}			
		}
	}

Showed me that the second if (OurMovementComponent->UpdatedComponent) is not == the RootComponet, so this part fails.
I initialize the OurMovementComponent in the constructor like this:

OurMovementComponent = CreateDefaultSubobject<UCollidingPawnMovementComponent>(TEXT("CustomMovementComponent"));
	OurMovementComponent->UpdatedComponent = RootComponent;

When you have any idea what I am doing wrong or what is wrong with documentaion tell me. :slight_smile:

PS: Sorry for the Clickbait :smiley:

Oh and by the way my RootComponent looks like this:

 CollisionSphere = CreateDefaultSubobject<USphereComponent>(TEXT("Collision Sphere"));
    RootComponent = CollisionSphere;

I have also tried the second if statement like this to check if there is something initialized in UpdatedComponent

if (OurMovementComponent->UpdatedComponent->GetName() == "Collision Sphere")

This test was true. So I think there must be something assigned to UpdatedComponent.

Hi, i’m following that tutorial as well, and currently stucked with my problem: My problem
Also, i checked, if i had the same as you, and yes, that statement isnt true for some reason if (OurMovementComponent->UpdatedComponent == RootComponent)
I hope your solution could help me deal with my own. Could u pls check my problem and maybe share some thoughts, if u allready went through it, or, at least, to say what helped you in your own’s. Thank you.
