Services and settings

The scene objects and assets around a view.

AuiLanguageService

One per scene, on a GameObject named AUI Language Service. Views find it by name at start, because a prefab cannot hold a reference to a scene object. Every view exposes it as lang.

Create it with AUI/Rebuild Language Table.

Language

int    GetLanguage();
string GetLanguageCode();
int    LanguageCount();
string LanguageName(int index);      // the native name, from the file's "_name"

void SetLanguage(int index);
void SetLanguageByCode(string code);
void ClearChoice();                  // follow the player's client language again

string Get(int key);                 // by key index; falls back to the default language
int    IndexOfKey(string key);       // slow path, for editor and debug code

A player's choice is persisted with VRChat's PlayerData, so it survives rejoining. Until they choose, the client's own language is followed. Changing it repaints every registered view.

Style variables, world-wide

void   SetStyleVariable(string varName, string value);
string GetStyleVariable(string varName);
int    StyleVariableCount();
string StyleVariableName(int i);
string StyleVariableValue(int i);

Unlike the same call on a view, this reaches every registered view in the scene, including views created later. See theming.

Other

void Register(AuiView v);       // views register themselves
bool TweensAvailable();         // false under ClientSim, where VRCTween is inert

AuiInputPanel

One per scene, on a GameObject named AUI Input Panel. The invisible click targets behind every <input>, because no Udon API opens VRChat's keyboard directly: a Text Panel with a TMP_InputField, and a Url Panel with VRChat's own VRCUrlInputField for <input type="url">. Each is its own canvas and collider; one is enabled at a time.

Create it with AUI/Rebuild Input Panel. Re-run it on a scene built before the url panel existed; the builder moves the old text field under Text Panel and adds the url one.

Field	Default	Meaning
distance	0.6	metres along the head ray where the target is parked
clickTimeout	3	seconds the player has to click the second time before it dismisses

An <input> therefore takes two clicks: the first arms the panel, the second opens the keyboard. You do not call this class yourself.

AuiSettings

One per project, at Assets/AUI/AuiSettings.asset, found by type. Editor-only: nothing reads it at runtime.

Create it with AUI/Create Settings.

Field	Default	Meaning
langFolder	Assets/AUI/lang	where the language JSON files live
defaultLanguage	en	the language a missing translation falls back to, and the one a missing key is an error in
componentFolders	empty	extra folders searched for nested views used by tag
iconFolders	empty	extra icon folders, searched before the package's own
extraCharacters	empty	characters to include in the font bake beyond what the language files use
unicodeRanges	Latin, Latin Extended, Greek, Cyrillic, punctuation, currency, arrows, CJK punctuation, fullwidth, U+200B	ranges always baked
fontSet		the baked AuiFontSet, assigned by AUI/Bake Fonts
boundTextSample	Mmmmmmmmmmm日	the string used to measure text="{binding}" elements that have no max-width

Keep a CJK character in boundTextSample

It makes bound text boxes as tall as the Noto fallback's line. A box shorter than a line renders nothing when the text is truncated, which looks like a bug and is hard to trace.

AuiFontSet

The baked fonts, at Assets/AUI/Fonts/AuiFontSet.asset. Produced by AUI/Bake Fonts; you do not edit it by hand.

Field	Meaning
regular, medium, semiBold, bold	one static atlas per Inter weight
cjkRegular, cjkBold	Noto JP, KR and SC atlases, in fallback priority order
dynamicLatin, dynamicCjk	dynamic atlases for runtime strings such as player names
bakedCharCount, bakedHash	what the last bake covered; drives the AUI600 staleness warning

Characters Inter does not have fall back to Noto JP, then KR, then SC.

AuiSignal

One per interactive element, added by the prefab builder. It relays a uGUI event into the view's dispatch. You never add or configure one, but you can drive one in a test:

signals[S_CLOSE].SendCustomEvent("_Click");

• Languages for the file format and the workflow.
• Menu and windows for the commands that create these.
• View API for the view side.
