Community C++ port of Advanced Locomotion System V4 for Unreal Engine: a third-person character locomotion framework with stances, gaits, rotation modes, mantling, ragdoll and footstep handling, rebuilt as a replicated plugin. The source code is MIT licensed. The maintainer now recommends newer locomotion systems for new projects, so treat this as a reference or a base for existing ALS projects.

active: License spot-checked at the source; the entry carries dated evidence.
Canonical URL: the original address github.com/dyanikoglu/ALS-Community now redirects to github.com/PanicPetal/ALS-Community, which the GitHub API reports as the repository's current full name; the README still links issues and the wiki under the old path
The README states: "Advanced Locomotion system is built upon pretty outdated animation programming techniques of pre Unreal Engine 5 era, and I highly recommended to utilize other available locomotion systems, such as Epic's Lyra sample project. This repository will only receive engine compatibility fixes from now."
Version recorded from the README ("for Unreal Engine 5.4") and the .uplugin, which declares "EngineVersion": "5.4.0"; release v4.26 (2024-07-09) is the 5.4 compatibility update and no later release exists
Supported platforms per the README are Windows and Linux; console, Mac and mobile are "not tested and supported"
C++ core with an Animation Blueprint; input uses Enhanced Input; setup instructions are on the repository wiki
The README scopes the licence to "Source code of the plugin"; the LICENSE copyright line credits LongmireLocomotion "as developer of the blueprints used as reference for source code"; the original marketplace ALS V4 content is a separate product under Epic's marketplace terms, so check any animations or meshes you take from the sample before redistributing them outside an Unreal project
MIT is compatible with the Unreal Engine EULA, which forbids combining engine code with copyleft licences such as GPL and LGPL; keep the copyright notice in your third-party credits
Maintenance: GitHub API (2026-10-13) reports the repository not archived, last push 2024-07-10; under three years, so no maintenance value is set, but the README limits future work to engine compatibility fixes
