Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to get the Rotator of an Actor/SceneComponent?

How would I go about either getting a pointer/reference to the Rotator of an Actor/SceneComponent OR Some way to change only a single Value(pitch/yaw/roll) of a Rotator of a scenecomponent/actor, without touching the others?

You're not supposed to change specific component directly through indirection. Here's what you're supposed to do:

 FVector NewPos = Actor->GetActorLocation();
 NewPos.Z = 1.0f;
 Actor->SetActorLocation(NewPos);

Same for Rotators

 FRotator NewRot = Actor->GetActorRotation();
 NewRot.Yaw = 30.0f;
 Actor->SetActorRotation(NewRot);

You can keep references to actors (preferably through a uproperty variable), and then Get/Set locations/rotations as needed, but not references to single parameters of location or rotation. 'Yaw', 'Pitch' and 'Roll' are not how those values are stored internally for an FRotator. Eulers are used because it's understandable for users, as opposed to quaternion components.

Ah, thank you for explaining that. Still a bit new to Unreal.
