Interaction System

Docs last synced: 2026-10-11 00:32 UTC

One shared interaction model for Unreal Engine 5.8 on desktop, mobile and VR: ray-based selection with local focus feedback, server-authoritative grabbing, one- and two-hand manipulation with profiles, physics items, a bow and arrow, rotary and linear handles, and a built-in debug panel. Works from Blueprint and from C++, in single-player and multiplayer.

What it covers

A source on the pawn (a camera or a VR hand) finds a target with a ray or a sphere and shows focus at once. The server validates every request, decides who holds what through a claim ledger, and explains every rejection with a reason. Items can be held by two hands of one player, scaled, thrown, attached to a surface or driven along a rotary or linear constraint. The documentation doubles as a tutorial: it has a glossary, seven step-by-step lessons and a debug-tools chapter.

Where to start

New to interaction systems? Read the Quick Start, then the step-by-step tutorials; unfamiliar words are in the glossary (Ukrainian: Швидкий старт, покрокові уроки, словник).

When something does not work, open the debug panel with the console command InteractionOverlay (Debug tools): it shows focus, hand state and the server's answer.
