BestoNet is a custom rollback networking solution developed for the fighting game [Idol Showdown](https://store.steampowered.com/app/1742020/Idol_Showdown/). Built in C# for Unity, it integrates with Facepunch Steamworks to provide a robust and efficient rollback implementation.
This is a work in progress as a library, and won't work right out the box

## Background
Originally we used Unity GGPO but there were some issues.
- Unplayable connections at long distances (experiencing ~7 frames of rollback)
- Maintenance difficulties due to GGPO's C++ codebase
- System instability during poor network conditions
- Using GGPO required a relay system that added extra latency to online matches
## Core Features
### Rollback Management
- **Speculative Frame Saving**: Saves CPU time and preventing 7 frame rollbacks
- Currently saves the midpoint frame, confirm frame, and end frame
- **Input Prediction**: Will predict the next input using the previously received input
- **Rift Management**: Many different options to deal with one sided rollback and game syncing
- **Reliable Input Messaging**: Maintains a 7-frame input buffer to handle packet loss and out-of-order delivery
## Implementation Requirements
1. Frame Timing: Idol Showdown currently uses a separate thread as a timer.
2. Spectator: The current implementation contains a call to send confirmed frame inputs to a spectator buffer
3. State management system: Deterministic game logic is required. For efficiency reasons, we recommend avoiding using byte[] with BinaryWriter/Reader
## Configuration
**Current Unity Configuration Settings**
## Credits
This implementation draws inspiration from:
- MK/Injustice GDC presentation
- Zinac's rollback implementation guide
- GekkoNet's Rollback System
Special thanks to [Rin Iota](https://x.com/sss_iota_sss) for developing the original networking foundation that enabled ISD Rollback's creation.
