A new version of the Inventory System is available with more multiplayer-related features. The Multiplayer Interaction Demo can now run in multiple modes, through two separate implementations of the Character scene: The simple character scene leverages the MultiplayerSynchronizer and can either let the client have authority and move the character, or have the client send inputs to the server, which then applies the movement logic server-side. A separate netfox character scene leverages the netfox addon to implement client-side prediction and server reconciliation.
Features:
Added a “drop all items” to the GGInventoryUI toolbar.
Added a GGAccessTestPolicy to the access manager for delay and failure testing of policies.
Added crafting to the main tour
Added crafting recipe collection
Added MyMultiplayerSpawner, which reads scenes from a directory to populate its auto spawn list
Added hotbar access policy
Hotbar tracks item when its moved around in the inventory
The GGInventory’s items_changed signal now supports batching
The GGInventory’s swap_items() method now atomic/emits a single items_changed signal
Added reusable MyItemDropHandler to drop items near character within configurable distance
Multiplayer Interaction demo character now includes two versions; A “simple” version, and a “netfox” version for client-side prediction.
Added Multiplayer Lobby demo; similar to the Multiplayer Interaction demo, but uses WebRTC with a lobby server that allows clients to join via lobby code.
Added window management examples to main tour
Added link to multiplayer lobby demo to main tour for web build
The main tour theme selector now uses the resource name as the theme name

Godot-matcha is an addon that lets you use WebRTC for multiplayer games by handling matchmaking using WebTorrent trackers. Conceptually it’s quite an interesting, novel approach. WebTorrent uses a modified BitTorrent protocol that allows it to work with WebSockets. A WebTorrent tracker is essentially a directory service that keeps track of torrents offered by users. A …
For some reason, my Godot game would no longer launch on the Steam Deck. I could hear it running as if it were running in the background, but the screen kept showing the Steam Deck’s UI. Since it’s all Linux I figured it should be possible to just drop to the command line and launch …
When I think of video games, I generally still think of an application that is downloaded and runs on the client. Technically, that’s still the case with web-based exports from Godot Engine, since the web browser has to download the files before being able to run them. I thought maybe I could just run the …
