FNP Patcher

The build for Javaagent is only released on GitHub.

This is an extension mod for Krypton Fabric, ported from KryptonFNP.

Feature

• More basic optimizations
• RecastLib provides acceleration features for Windows (x64/arm64)

Install

Install directly as a Mod.

Starting from version 26.1.2, the Mod body no longer includes the Patcher and JavaAgent modules. If you still want them to take effect, please see README.

Config

Add the following parameters to the Java startup parameters to control the mixin enablement:

Parameter	Description	Default value	Configuration in file form
velocity.natives-disable	Disable Native	false	Not supported

example:

java -Dvelocity.natives-disable=true -jar neoforge_launcher.jar

Dependencies

• Krypton Fabric - Optional dependency. I put some optimizations here.
