Descripción
The Life Engine
The Life Engine is a fully custom first-person movement framework for Unreal Engine 5, built entirely in C++ without relying on Unreal Engine's CharacterMovementComponent.
Designed for developers who want responsive, skill-based movement inspired by classic FPS titles, this plugin provides a complete movement solution featuring air strafing, bunny hopping, custom acceleration, custom friction, custom gravity, crouching, runtime key rebinding, and configurable movement presets.
The system is implemented from the ground up using a standalone movement component and pawn architecture, giving developers full control over movement behavior without fighting against the limitations of the default Character Movement system.

Classic FPS Movement Presets
Includes multiple movement presets inspired by classic shooter movement styles:
GoldSrc-inspired movement
Source-inspired movement
Quake-inspired movement
Fully customizable preset
Developers can quickly switch between movement styles or create their own custom configuration.
Advanced Air Movement

Air strafing
Air acceleration
Momentum preservation
Skill-based movement control
Perfect for movement-focused shooters and arena-style gameplay.
Bunny Hopping
