Cores

简体中文

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.

Developer Features

Developer Features
  • Color Schemes : When using this mod's Screen or certain rendering-related code, you can customize the color palette by changing the color scheme (as shown in the images below). Press the Home key to open the configuration interface: Home Screen Select a color scheme: Select Color Scheme Save and view the results: Amber Sunset Teal Twilight
  • Network Listening : Listens on port 4444 and 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);
    }
}
