How do GlobeAwareDefaultPawn move forward in the world

Cesium for Unreal
1

Hi, I use this code to move forward, but it will move down and forward

this->_moveAlongViewAxis(EAxis::X, Val);

I just want to move along the ellipsoid

Hello @http3w ,

You may be able to try creating a longitude-latitude-height values that gradually change when given input. In Tick, you can use the updated longitude-latitude-height to set the position of your actor. Adjusting only the longitude-latitude will let you move along the ellipsoid. To convert from longitude-latitude-height to Unreal coordinates, you will need to use the conversion functions on the CesiumGeoreference. Let me know if that idea works for your use case!

@Nithin_Pranesh thanks for your reply. That’s right;
this my code:

FVector LongitudeLatitude = GlobeAnchor->InaccurateGetLongitudeLatitudeHeight();
		FVector UnrealForwardVector = FRotationMatrix(FRotator(Controller->GetControlRotation())).GetScaledAxis(EAxis::Y) * Val * -10000.f + GetActorLocation();
		FVector UnrealToLongitudeLatitude = GlobeAnchor->GetGeoreference()->InaccurateTransformUnrealToLongitudeLatitudeHeight(UnrealForwardVector);
		FVector UnrealVector = GlobeAnchor->GetGeoreference()->InaccurateTransformLongitudeLatitudeHeightToUnreal(FVector(UnrealToLongitudeLatitude.X, UnrealToLongitudeLatitude.Y , LongitudeLatitude.Z));
		SetActorLocation(UnrealVector);
