the normal easy answer:
Create BP from mesh etc.
Spawn BP Actor - Spawn Actor From Class (node) - needs a local transform where it initially starts at
Move Actor - AddActorLocalOffset (node) - use vector to move (usually a break & make vector and move it on the x,y,or z axis)(using a timeline, timer, and if in a hurry or testing event tick (not advisable for finished game)
lots of documentation & tutorials on the different approaches but that’s pretty much it, put simply.
