Note

New update: 3.1.0: Reactive holograms. Scroll down for more information.

HoloEasy is a simple, modern and high-performant Java and Kotlin Minecraft Hologram library for 1.8-1.20.4 servers.

Quickstart

Requirements

• ProtocolLib installed on your server

Add dependency

Maven

<dependency>
    <groupId>com.github.unldenis</groupId>
    <artifactId>holoeasy</artifactId>
    <version>3.1.1</version>
</dependency>

Gradle

implementation("com.github.unldenis:holoeasy:3.1.1")

Make sure you include the repository as well.

Start programming

Java

import static org.holoeasy.builder.HologramBuilder.*;

// you can use a Pool or a org.bukkit.Plugin for HologramKey
IHologramPool pool = HoloEasy.startInteractivePool(plugin, 60, 0.5f, 5f);

public void addHologram(Location location) {
    hologram(new HologramKey(pool, "unique-id-holo"), location, () -> {
        textline("Hello");
        textline("Score {} - {}", 0, 1);
        clickable("Click me").onClick(p -> {
            p.sendTitle(ChatColor.AQUA + "Hi", ChatColor.BOLD + "by HoloEasy",
                    20, 20, 20);
        });
        item(new ItemStack(Material.ENCHANTED_GOLDEN_APPLE));
    });
}

Kotlin

import org.holoeasy.builder.HologramBuilder.*

// you can use a Pool or a org.bukkit.Plugin for HologramKey
val pool = startInteractivePool(plugin, 60.0, 0.5f, 5f)

fun addHologram(location: Location) {
    hologram(HologramKey(pool, "unique-id-holo"), location) {
        textline("Hello")
        textline("Score {} - {}", 0, 1)
        clickable("Click me").onClick {
            it.sendTitle(ChatColor.AQUA + "Hi", ChatColor.BOLD + "by HoloEasy",
                20, 20, 20)
        }
        item(ItemStack(Material.ENCHANTED_GOLDEN_APPLE))
    }
}

Reactive Holograms

From 3.1.0 version, the parameters of text lines and item lines can also be reactive. This means that you can update the line by simply calling the 'set' method to these.

Warning

Mutable states have no player information at this time. If you need to create a hologram for a specific player, it is recommended that you do not add it to a Pool.

Java

var clickCount = mutableStateOf(0); // can be any type

var holo = hologram(new HologramKey(plugin, "unique-id-holo"), location, () -> {
    textline("{}!", "Static");
    textline("Count: {}", clickCount);
    clickable("Click me", 0.5f, 5f).onClick($ -> clickCount.set(clickCount.get() + 1));
});

// It hasn't been added to a pool, so it's up to us to make it visible and hide it from players. It's better to use a pool because it's automatic and performs asynchronous operations.
// HologramKey decides whether to add it to a pool or not.
holo.show(player);

Kotlin

val clickCount = mutableStateOf(0) // can be any type

val holo = hologram(HologramKey(plugin, "unique-id-holo"), location) {
    textline("{}!", "Static")
    textline("Count: {}", clickCount)
    clickable("Click me", 0.5f, 5f).onClick { clickCount.set(clickCount.get() + 1)}
}

// It hasn't been added to a pool, so it's up to us to make it visible and hide it from players. It's better to use a pool because it's automatic and performs asynchronous operations.
// HologramKey decides whether to add it to a pool or not.
holo.show(player)
