This tutorial covers modern locomotion in Unreal Engine from start to finish. It begins by explaining how State Machines work, their limitations, and why Epic Games introduced Motion Matching. Then it breaks down Motion Matching in UE 5.5 and finally explores GASP in UE 5.7, including the Mover plugin and Locomotor system, to help you understand the future of character movement in Unreal Engine.
