What surface are you colliding with in the editor?
From my post: In my test, I’m simply colliding with a basic cube (Modes->Place->Basic->Cube) static mesh actor.
Where are you including this code?
Just the Tick function for a random actor.
SphereStartLoc is a world position I get form a reference target actor. For SphereEndLoc I simply add 10.0 to Z of the start loc.
float Radius = 35.0f;
FVector SphereLoc = RefActor->GetActorLocation();
FVector EndLoc = SphereLoc;
EndLoc.Z += 10.0f;
I use DrawDebugSphere to show where I’m doing the sphere collisions and it looks exactly right:
DrawDebugSphere(GetWorld(), SphereLoc, Radius, 12, FColor::Red, false, -1.0f);
DrawDebugSphere(GetWorld(), EndLoc, Radius, 12, FColor::Yellow, false, -1.0f);
