d5ec2fbd11One off inputs are recorded on NetworkTİme.after_tick. Before that* commit rollback inputs were recorded from rbs after_tick. After that commit rollback inputs are recorded from network-rollback after_tick. Godot calls signals based on their connected order. Before server update rbs's were connecting their signals with a deferred call. This was resulting in one off input node winning the race. But after the server update, since servers are initialized before anything else, input nodes are always losing the race. This pr fixes the race condition by explicitly calling NetworkRollback methods, instead of relying on signal connection order. --------- Co-authored-by: Tamás Gálffy <ezittgtx@gmail.com> |

C# Support
For experimental C# support, see the Netfox Sharp repo, and the corresponding Netfox Sharp guide.
Install
Releases
Find the latest netfox under Releases
Each release contains the addons, and a build of Forest Brawl for Windows and Linux. Each addon has its dependencies packed with it - e.g. "netfox.extras.vx.y.z.zip" also contains both netfox and netfox.internals.
Note: For releases before v1.1.1, a separate ".with-deps.zip" version contains the addon and its dependencies, while the regular zips contain only the addon itself.
Asset Library
Search for the addon name in Godot's AssetLib or download from the site:
Source
Download the source and copy the addons of your choice to your Godot project.
Enable the addons
After adding netfox to your project, make sure to enable the addons in your project settings. Otherwise, Godot will present you with errors about undeclared identifiers.
Upgrading
If you're upgrading from an older version of netfox, refer to the upgrade guide.
Usage
See the docs.
Supported versions
Godot 4.x is supported by netfox. If you find any issue using any supported version, please open an issue.
Forest Brawl and the other examples are written against Godot 4.1. They may or may not work when opened with any other version.
Prototyping
To try your game online with noray, a free to use instance is hosted at
tomfol.io:8890, the same instance used by Forest Brawl.
You can use this noray instance to quickly test your games online, but is not recommended for shipping games. The instance has configured limits, and no uptime guarantees are made.
Examples
Comparison sample
To provide a short intro on how to get started with netfox, and how it fares compared to built-in multiplayer tools, a simple demo was implemented as a single-player game, which was ported to multiplayer using both a naive approach and netfox.
Feature examples
Each of these examples give a starting point to a specific feature:
- Input gathering
- State machines
- Multiplayer FPS
- Rollback Debugger
- Property Configuration
- Input prediction
- NPCs with rollback
- NPCs with StateSynchronizer
- Visibility filtering
Example games
Forest Brawl
To provide examples of netfox usage in an actual game, Forest Brawl was created and included specifically for this purpose.
It's a party game where an arbitrary amount of players compete by trying to knock eachother off of the map.
Godot Rocket League
Play soccer with cars, in Godot, with Godot Rocket League!
Demonstrates netfox's physics rollback capabilities, ensuring smooth and responsive physics-based gameplay.

Contribution
Contributions are welcome! Please feel free to fork the repository and open a PR. Ideally, your PR implements a single thing, optionally refers to an existing issue, and follows the GDScript style guide.
Please note that depending on the feature/fix you implement, the PR may need to undergo changes, or in some cases, get rejected if it doesn't fit netfox's intended feature set or vision.
If you feel like it, grant the netfox author(s) write permission to your fork, so we can update the PR if needed.
If you're not sure if the PR would fit netfox or not, open an issue first, mentioning that you'd be willing to contribute a PR.
