Texte erstellen

Formatted text can be created using Component factories as described in this section. The robust text API can be used in a variety of ways to combine styling, coloring, and actions.

Unformatierter Text

Oftentimes, all you need is unformatted text. Unformatted text is the simplest form of text to create.

Beispiel:

import net.kyori.adventure.text.Component;

Component unformattedText = Component.text("Hey! This is unformatted text!");

Der oben gezeigte Beispielcode gibt ungefärbten, unformatierten test ohne text actions zurück.

Formatted Text

The Component interface allows for the creation of formatted text in a „building-block“ style. Components in Adventure act like builders where any Component can be amended with colors, decorations, etc. Components are immutable, so using these builder-like methods will create a copy each time. There is no need to call .build() at the end, unlike with Sponge’s previous Text API from API 7 and below.

Tipp

Read this Wikipedia article for help understanding the purpose of the builder pattern in software design.

Farben

One usage of the text API is the addition of colors to text, as illustrated below.

Beispiel: Farbiger Text

import net.kyori.adventure.text.format.NamedTextColor;

Component coloredText = Component.text("Woot! Golden text is golden.", NamedTextColor.GOLD);

Any Minecraft color specified within the NamedTextColor class can be used when coloring text, as well as full-RGB colors using TextColor. Multiple colors can be used in text by appending additional texts with different colors:

Beispiel: Mehrfarbiger Text

import net.kyori.adventure.text.format.TextColor;

Component multiColoredText = Component.text("Sponges are ", NamedTextColor.YELLOW).append(
        Component.text("invincible!", TextColor.color(0x5fb0ff)));

Styling

The API can also be used to style text, including underlining, italicizing, etc. This is called „decorating“ in the Adventure library.

Beispiel: Gestylter Text

import net.kyori.adventure.text.format.TextDecoration;

Component styledText = Component.text("Yay! Styled text!").decorate(TextDecoration.ITALIC);
Component shortcutText = Component.text("Shortcut for both!", NamedTextColor.GRAY, TextDecoration.UNDERLINE);

Genau wie schon bei den Farben gezeigt, kann auch die Textformatierung Verkettet werden.

Beispiel: Mehrfarbiger Text

Component multiStyledText = Component.text("I'm italicized! ").decorate(TextDecoration.ITALIC)
        .append(Component.text("I'm bold!").decorate(TextDecoration.BOLD));

Text Events

Components also offer the ability to create actions for text. Any action within the HoverEvent or ClickEvent classes can be used when creating text actions for text. Sponge provides additional actions in SpongeComponents. The method below is a small example of what text actions can do.

Example: Text with an Event

import net.kyori.adventure.text.event.ClickEvent;

Component clickableText = Component.text("Click here!")
    .clickEvent(ClickEvent.runCommand("tell Spongesquad I'm ready!"));

Component callbackText = Component.text("Click here too!")
    .clickEvent(SpongeComponents.executeCallback(
        cause -> cause.audience().sendMessage(Component.text("You clicked!"))));

In der oben gezeigten Methode kann der Spieler auf den „Click here!“ Text drücken, um einen Befehl auszuführen.

Bemerkung

Some text actions, such as ClickEvent#changePage(int), can only be used with book items.

Tipp

Just like with colors, multiple actions can be appended to text. Text actions can even be used in tandem with colors because of the builder pattern interface.

Selektoren

Ziel-Selektoren werden genutzt, um bestimmte Spieler oder Entitys auszuwählen, die eine bestimmte Bedingung erfüllen. Ziel-Selektoren habe teilweise Nutzen in Plugins für Minispiele, werden aber für viele Anwendungsbereiche benötigt.

Tipp

Read this Minecraft wiki article for help understanding what target selectors are in Minecraft, and how to use them.

To use selectors in text, there is a component factory for Selectors. This is illustrated in the example below.

Example: Selector-generated Text

Component adventurers = Component.text("These players are in adventure mode: ")
        .append(Component.selector("@a[m=2]"));

In this example, the target selector @a[m=2] is targeting every online player who is in adventure mode. When the method is called, a Component will be returned with a selector of all the usernames of every online player who is in adventure mode. To send this selector to players, the selector will have to be expanded to the real usernames using SpongeComponents#resolve.

Text Builders

Mutable builder classes exist for every kind of Component. These are available should you need a mutable representation, and they are also used in a few convenience methods throughout the library to expose parts of an existing Component for editing.

Example: Text Component builder

Component weBuiltThisText = Component.text()
        .content("with Sponge and Flard")
        .color(NamedTextColor.YELLOW)
        .decorate(TextDecoration.ITALIC, TextDecoration.BOLD)
        .build()

Example: Editing text with a StyleBuilder

Component limitedEdition = weBuiltThisText.style(
        styleBuilder -> styleBuilder.decorate(TextDecoration.UNDERLINE));
