HyperLightBCL Branch ​

HyperLightBCL is a Rust implementation branch separated from Bad Craft Launcher, continuing to maintain the design philosophy of Bad Craft Launcher. The Rust hybrid implementation in Bad Craft Launcher will modify portions of the code based on this project.

Why does this development branch exist? ​

Because Rust offers exceptional memory safety, effectively preventing player privacy leaks. Additionally, HMCL's Taowa Multiplayer and PCL-CE & FCL Multiplayer implementations are based on EasyTier, which is developed in Rust. Since our efficient multiplayer method will also be developed using Rust, we will modify portions of EasyTier's source code.

Another reason is that Rust's resource occupancy is extremely low, which can reduce the load on older devices and provide players with a smooth gaming experience.

Note

This project is separate from Bad Craft Launcher, including the portion of code implemented with Rust hybrid approach.

When submitting issues, please submit them to the corresponding project. Otherwise, the issues will be mercilessly closed.
