Performance optimized & replicated C++ port of Advanced Locomotion System V4 for Unreal Engine 4.25+
- Converted into plugin structure (by AHGS-Jens). You can immediately start using it in your project without doing any serious change in your project configuration.
- Source code is highly optimized while being ported from blueprints. For 100 characters in a scene, CPU time is decreased from ~17ms to ~10ms.
- Network performance optimized, and comes with full replication support (Big kudos to senfkorn92 for his work). ALSV4_CPP currently beats ALS V3 and other BP based V4 replication implementations on network performance:
Advanced Locomotion System V3 (BP):
Total outgoing bandwidth is 686KB over 60 seconds (30 seconds playing server, 30 on client).
Character Actor Data sent over network - 43KB
'ReplicatedMovement' Data sent over network - 19KB
Highest RPC Data sent over network - 90KB
Overall Property Size - 46KB
Overall RPC Size - 201KB
Advanced Locomotion System V4 (BP):
Total outgoing bandwidth is 2.7MB over 60 seconds (30 seconds playing server, 30 on client).
Character Actor Data sent over network - 116KB
'ReplicatedMovement' Data sent over network - 45KB
Highest RPC Data sent over network - 536KB
Overall Property Size - 209KB
Overall RPC Size - 1.7MB
Advanced Locomotion System V4 (C++):
Total outgoing bandwidth is 618KB over 60 seconds (30 seconds playing server, 30 on client).
Character Actor Data sent over network - 38KB
'ReplicatedMovement' Data sent over network - 14KB
Highest RPC Data sent over network - 48KB
Overall Property Size - 41.1KB
Overall RPC Size - 91.1KB
