Advanced Ledge Locomotion System on UE5 - Overview
This video showcases a fully modular Advanced Ledge Locomotion System built in Unreal Engine 5. The system was originally implemented for GASP, but it works with any UE5 project.
Instead of relying purely on dynamic calculations, this system uses level-driven Ledge Markers and Tags to control behavior. That means level design directly drives gameplay interaction giving designers you full control over how the character will behave on different surfaces.
💡 Core Concepts Explained
Ledge Markers control attachment so if no marker, no grab
Color-coded surfaces: supported, free hang, slippery, and poles
Tag-based direction system to avoid rotation glitches
Automatic climb-up using the “Top” tag
Explicit direction logic instead of unstable dynamic rotation
Master Chooser + Secondary Chooser tables for clean animation selection
Fully modular Ledge Component architecture
🎮 Features Demonstrated
Supported ledge climbing
Free hang mode
Inner and outer corner transitions
Pole traversal (vertical logic)
Supported ↔ Free Hang transitions
Drop down to lower ledges
180° backward leap transition
Per-character hand alignment adjustments
Character switching (N key)
🏗️ System Architecture
95% of logic inside a single Ledge Component
Clean Character Blueprint (no bloated logic)
Trace detection & surface validation
Direction calculation using tags
Animation selection via Chooser System
Animation Blueprint only handles idle blending
Expandable without rewriting core logic
⚠️ Important – Animations
This system uses animation packs from the Unreal Marketplace.
Due to licensing restrictions, animations are not included in the project.
You must purchase the animation pack separately (link below).
