Precompiled per engine version, because the projects that need this cannot compile C++.

Why binaries

Unreal exposes no HTTP and no JSON to Blueprint, so the plugin has to contain C++. But a survival template bought from the marketplace usually has no Source/ folder at all, which means the project cannot build C++ even if it wanted to. So we ship compiled binaries, one build per engine version, and a zip drops in with no toolchain involved.

Install

Close the editor first — Unreal reads Plugins/ once at startup.

Engine versions

A plugin zip is built for one engine version and refuses to mount on another. Unreal checks the compatible version rather than the exact one, so the descriptor is stamped MAJOR.MINOR.0.

What you get in Blueprint

• Raid State - Authenticate Player — provider and ticket in, a player id out.
• Raid State - Ensure Container — find-or-create a stash, returning its contents.
• Raid State - Grant Item, Move, Consume, Split, Merge.
• Raid State Stash Panel — a widget that draws a container and can deposit and withdraw.
• Raid State - Sync Container From USME — reconciles a template inventory in one versioned transaction.

Offline behaviour

Mutations are queued to disk with stable idempotency keys and replayed when the platform comes back. A retried grant cannot become two items, because the key is derived from the operation rather than generated per attempt.
