Unreal uses a left-handed coordinate system with: X: Forward. Y: Right. Z: Up.
Each object with a transformation has both a global/world and a local/object space. Switch mode with the Cycle Transform Gizmo Coordinate System button in the top-right of the viewport. The button icon is either a globe (global/world space) or a box (local/object space).
We can find the current transformation of an Actor using GetActorTransform.
We can find the current transformation of a Component with GetComponentTransform.
We can find the local/relative transformation of a Component with GetRelativeTransform.
GetReltiveTransform answers the question "Where am I relative to the argument?".
With a Transform we can do TransformDirection.
