Migrating from the BungeeCord Chat API#
Adventure’s text API and the BungeeCord Chat API are designed along very different lines. This page goes over some notable differences.
It is strongly recommended you read about Audiences first. Unlike BungeeCord, which limits functionality to specific user types, Adventure allows only the specific operations that apply to an audience to be taken.
Decoration and Styling#
The BungeeCord Chat API stores all decorations in the
BaseComponent. Adventure separates
out styles into their own
BungeeCord allows you to merge the styles from one component into another. Adventure provides equivalent methods that merge styles together, or allows you to replace the styles on one component with another.
Adventure’s chat color and styling hierarchy differs from that of BungeeCord’s
API. This is probably where the most stark contrast between the Adventure API and BungeeCord/Bukkit
Adventure’s equivalents for
ChatColor are split over three types:
Formatting types (such as
ITALIC) are in
TextDecoration, and can be set on a component or a style with the
decorationmethod. Decorations also use a tristate to specify if they are enabled, disabled, or not set (in which case the component inherits the setting from its parent component).
Named colors (also called the legacy Mojang color codes) now exist in the
RGB colors are constructed using the
TextColor.color()methods (this is equivalent to the
ChatColor.of()method in the BungeeCord
Legacy strings can’t be constructed#
ChatColor API’s heritage is in the Bukkit API. The Bukkit
ChatColor API in turn
dates from the early days of Minecraft (Beta 1.0), when the normal and accepted way of sending formatted
messages to the client was to concatenate magical strings that told the client what to format. A formatted
chat message would be sent to the client like this:
player.sendMessage(ChatColor.GREEN + "Hi everyone, " + ChatColor.BOLD + "this message is in green and bold" + ChatColor.RESET + ChatColor.GREEN + "!");
This style of sending messages has persisted to this day, even as Mojang introduced rich chat components
into Minecraft 1.7.2. Bukkit preserved this backwards-compatible behavior, and BungeeCord introduced the
change as a result of being compatible with the Bukkit
In Adventure, you can’t concatenate magical formatting codes. The equivalent of
ChatColor in Adventure,
TextColor, instead returns descriptive text describing the color when its
toString() is called. The
recommended replacement is to convert all legacy messages to components.
ChatColor.stripColor() does not exist in Adventure. An equivalent would be to use
ChatColor.translateAlternateColorCodes() does not exist in Adventure. Instead you should use
LegacyComponentSerializer.legacy(altChar).deserialize(input) when deserializing a legacy
ComponentBuilder treats each component independently and allows you
to manually carry over styles from a prior component. In Adventure, there are multiple
component builders. The closest equivalent for a BungeeCord
to append components to a top-level empty component using
as a base. To replicate the behavior of
ComponentBuilder, consider doing the
Styleclass to store common styles and the
stylemethods to merge and replace styles on a component.
Use the Adventure
TextComponentbuilder to create one component at a time and then append to a top-level text component builder that is empty.
As an example, this BungeeCord component:
new ComponentBuilder("hello") .color(ChatColor.GOLD) .append(" world", FormatRetention.NONE) .build()
becomes this Adventure equivalent:
Component.text() .append(Component.text("hello", NamedTextColor.GOLD) .append(Component.text(" world")) .build()
new ComponentBuilder("hello") .color(ChatColor.GOLD) .bold(true) .append(" world") .build()
Style style = Style.style(NamedTextColor.GOLD, TextDecoration.BOLD); Component.text() .append(Component.text("hello", style) .append(Component.text(" world", style)) .build()
In the BungeeCord Chat API, all components are mutable. Adventure text components, however, are immutable - any attempt to change a component results in a new component being created that is a copy of the original component with the change you requested.
The BungeeCord Chat API includes three serializers. All three have equivalents in Adventure:
TextComponent.fromLegacyText()deserialization method is equivalent to the
deserializemethod of the Legacy text serializer. Likewise, the
BaseComponent.toLegacyText()serialization method is equivalent to the
serializemethod on the legacy text serializer.
TextComponent.toPlainText()serialization method is equivalent to the
serializemethod of the Plain text serializer. A component can be created from a plain-text string using
The Adventure equivalent of
ComponentSerializeris the Gson text serializer.
BungeeCordComponentSerializer allows you to convert between Adventure Components
and the native BungeeCord chat component API and back. This can be used when native platform support is
unavailable. The serializer is available in the
