Creating Text
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.
Unformatted Text
Oftentimes, all you need is unformatted text. Unformatted text is the simplest form of text to create.
Example:
import net.kyori.adventure.text.Component;
Component unformattedText = Component.text("Hey! This is unformatted text!");
The code excerpt illustrated above will return uncolored, unformatted text with no text actions configured.
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.

Colors
One usage of the text API is the addition of colors to text, as illustrated below.
Example: Colored 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:
Example: Multi-colored 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.
Example: Styled 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);
Just like with colors, multiple styles can be used by chaining together separately styled texts.
Example: Multi-styled 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 the method above, players can click the „Click here!” text to run the specified command.
Megjegyzés
Some text actions, such as ClickEvent#changePage(int), can only be used with book items.
Javaslat
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.
Selectors
Target selectors are used to target players or entities that meet a specific criteria. Target selectors are particularly useful when creating minigame plugins, but have a broad range of applications.
Javaslat
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));
