CourierAPI

Minecraft 版本： 26.1.2

平台： fabric

标签： library utility

CourierAPI is a Fabric mod library that lets any mod send animated HUD notification cards to players — via the Java API, JSON files, or in-game commands. Supports server-to-client broadcasting and client-side local display.

Features

• Animated slide-in / slide-out cards in the top-right corner of the HUD
• Fully customizable colors — title, description, background, and border accent (ARGB)
• Configurable display duration per notification
• Up to 4 notifications visible at once; extras queue automatically
• Description wraps to a second line when text is too long
• Server → Client — send notifications via Java API or JSON files, no coding required
• Client-only — display notifications locally from another client mod without a server
• Drop-in /courier command for operators
• Auto-creates a sample couriernotifications.json on first server start

For Developers

Add to your gradle.properties:

courierapi_version=0.1

Then in build.gradle:

repositories {
    maven {
        name = "LunazStudios"
        url  = "https://maven.lunazstudios.com/releases"
    }
}

dependencies {
    modImplementation "com.lunazstudios:CourierAPI:${project.minecraft_version}-${project.courierapi_version}"
}

Full documentation and API usage examples are available on the GitHub repository.

Server API

Notification n = Notification.builder("Event Started!", "Head to the arena.")
        .durationSeconds(6)
        .borderColor(0xFFFF4444)
        .build();

CourierAPI.send(player, n);        // single player
CourierAPI.broadcast(server, n);   // all online players

Client API

// Client-side only — do not call on a dedicated server
CourierClientAPI.showLocal(n);

JSON — No Coding Required

Place couriernotifications.json in your server root to define reusable notifications:

{
  "restart_warning": {
    "title": "Server Restart",
    "description": "The server restarts in 5 minutes.",
    "duration": 8,
    "border_color": "#FF5555"
  }
}

Trigger them in-game with /courier send restart_warning, or drop entries into
couriernotifications_queue.json to dispatch from external scripts or RCON — no restart needed.

Commands

Requires permission level 2 (operator).
