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.

- Network Listening : Listens on port
4444and returns the registered content when accessed by players.
package dev.anye.mc.cores.am.listen;
// For detailed code, please check the dev.anye.mc.cores.am.listen package
// Here is an ImageListen instance
public class ImageListen extends Listen {
protected ImageListen() {
super("assets/cores/html/image/",// Resource path (optional). If provided, files under this path will be automatically loaded upon access.
"image",// Registration path, used to access this instance (e.g., 127.0.0.1:4444/image/index.html)
300// Shutdown timeout (seconds). Closes this listener after a period of inactivity.
);
}
// 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);
}
