Built on Bimdav's Delta Rollback Addon
Built using David Snopek's SG Physics 2D Addon
This project was made both as a resource to provide example implementations of many common fighting game features as well as using SG Physics 2D, a deterministic physics engine designed with rollback netcode in mind, with the Godot Rollback Addon using Godot 4.2.2. Bimdav's "Delta Rollback" is a fork of the original Godot Rollback Netcode addon by David Snopek which ports all of the core functionality to C++ as a GDExtension which gives much better performance! It is generally used in the same way as the original addon so if you want to get started you can follow along Snopek's absolutely excellent tutorial series! While his tutorial is a great resource, there will be differences in syntax since it was made for Godot 3. I recommend looking through my project and BimDav's example project for getting the addon running within Godot 4.
- A "FightManager" node which manages the order methods are called on all gameplay-related nodes
- A simple node-based state machine implementation
- An input system with a command buffer to interpret motion inputs such as quarter circles (executed as down, downforward, forward)
- Fighter push interactions
- Fighter hurtbox/hitbox system where hitboxes are assigned behaviors to decide what to do on block, on hit, or on air hit
- High/low blocking
- Projectiles
- Health bars and round restarting once a player is KO'd
All fully functional with rollback netcode, the gold standard solution for fighting game netplay!!!!
