Cores
This mod has a built-in Core library.
A library mod developed for Minecraft mod development. It packages numerous frequently used, repetitive code blocks and offers several practical features.
Player Features
- Attribute Fix : Modifies the default, maximum, and minimum values of attributes. This can be adjusted via the configuration file.
- Experience Fix : Modifies experience deduction. When deducting experience levels, it deducts the exact amount of experience points required to level up from level 0 to the target level, instead of using the vanilla calculation of (current level - target level) points. Both of the above features can be disabled via the configuration file.

);
}
// This method has a default implementation that dispatches POST and GET requests to their respective handlers; you can also override it to implement your own logic.
public void handle(HttpExchange exchange){}
}
// How to register
public class ListenRegister {
// Get registry
public static final Register<Listen> LISTEN_REGISTER = new Register<>(Cores.MOD_ID, "listen", builder -> builder.sync(false));
// Register instances
public static final DeferredHolder<Listen,ImageListen> IMAGE_LISTEN = LISTEN_REGISTER.register("image", ImageListen::new);
//public static final DeferredHolder<Listen,ExampleListen> EXAMPLE_LISTEN = LISTEN_REGISTER.register("example", ExampleListen::new);
// Call this method during mod initialization
public static void register(IEventBus eventBus){
LISTEN_REGISTER.register(eventBus);
}
// Assuming this is your Mod initialization function (constructor)
public Cores(IEventBus modEventBus, ModContainer modContainer) {
ListenRegister.register(modEventBus);
