How it works, step by step
- 1
Inventory state lives server-side; client receives a snapshot + delta events.
- 2
Grid renders slots from a template; item icons map from a config module.
- 3
Drag-and-drop swaps slot indices locally then commits MoveItem{from,to} to the server.
- 4
Server validates ownership + bounds, applies, broadcasts the delta to keep other UIs honest.
- 5
Tooltips read item metadata (name, rarity color, description) from the shared config.
Concepts you'll use
- Snapshot + delta sync
- Optimistic drag with commit
- Metadata-driven rendering
Mistakes that cost you players
- Client-owned inventory state gets duplicated by exploiters instantly.
- Drag operations without server commit vanish items on lag spikes.
