Descrição
This is a technical system. Traversecraft is the movement code: C++, predicted on the client, checked on the server, for both the Character Movement Component and Mover. The environment in the video and the gallery is a showcase and is not included. The animations in the package are examples, meant to be replaced with your own or with Epic's Game Animation Sample.
Every move runs inside the movement system's own prediction. The owning client does not wait for the server, the server runs the same move from the same input, and a correction replays it like any other move. Nothing is switched off while it runs.
The moves
Vault, mantle and climb, fitted to the obstacle's real height (up to 3 m)
Ladders, straight or leaning, with a jump off and a climb off the top
Hang from ledges, shimmy, go round corners, jump from ledge to ledge, climb up
Slide under obstacles
Wall run and wall kick (off by default)
Ziplines and ropes
Co-op: brace to boost a teammate up, kneel at the edge to pull them after you
Measured
Dedicated server and two clients at 150 ms of lag and 5% packet loss:
CMC: about 2 corrections per traversal, a few centimetres each
Mover: under 1 rollback per traversal (Epic's Mover vault: 2.2 on the same course)
Traversecraft.Debug 1 draws each path and every correction, so you can check it yourself
For your project
Works with your own character: reparent a Blueprint character, or add the modes to your Mover component
Game Animation Sample: one right click sets it up
Full Blueprint access: 21 classes to make Blueprint children of, 140 calls, events and settings
AI nav links, Gameplay Ability System tasks, Traversal Hand IK node for hands on the real edge
Root motion animations stretched to each obstacle, still predicted
Requirements
- Traversecraft turns on three of Epic's engine plugins it depends on: Mover (the Mover version), Enhanced Input (the example character's controls) and Gameplay Abilities (the Gameplay Ability System tasks). All come with the engine.
Included
The plugin (C++ source), for Unreal Engine 5.6, 5.7 and 5.8, Windows
A grey example map with every move and the example character
Example animations (meant to be replaced)
Not included
The environment art shown in the video and gallery (Abandoned Factory Buildings and Construction Site, sold separately on Fab)
Try it first: the demo (Windows, no engine needed) has the showcase and the plain example course: https://github.com/filipetessaro/traversecraft-demo
