An Introduction to the Mover Plugin | Unreal Fest 2024
Summary
The video introduces the new Mover plugin, addressing issues with the old system's steep learning curve, limitations, and complexity. It explains the need for a new character movement system to improve upon challenges like system complexity, character type limitations, and networking model issues. The Mover plugin offers modularity, composable inputs, and enhanced state management, providing benefits over the traditional Character Movement Component (CMC). Future plans include enhancing physics-based characters, animation support, trajectory queries, and anticipatory animations, aiming to improve scalability, performance, and overall user experience. The ongoing work focuses on animation improvements like bracing characters for impact, transitioning from root motion to controlled motion, and exploring multi-threaded movement capabilities to address current challenges.
