Tokens, turns and time describe resource use, not a dollar price.

This benchmark measured an earlier version of the skill.

A newer attempt on gemini-3.8-flash on 10/20/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.

Localization in Godot 4.3+

All examples target Godot 4.3+ with no deprecated APIs; GDScript first, then C#.

Related skills: godot-ui for Control nodes and theme management, save-load for persisting language settings, responsive-ui for layout adjustments per locale.

1. Core Concepts

How Godot Localization Works

Wrap all user-facing strings in tr() — Godot's translation function
Create translation files (CSV or PO) mapping keys to translated strings
Import translation files as Translation resources
Switch locale at runtime via TranslationServer.set_locale()

All Control nodes with text, tooltip_text, or placeholder_text properties auto-translate when the value matches a translation key.

Translation Key Strategies

Strategy	Example Key	Pros	Cons
Semantic keys	`MENU_START_GAME`	Clear intent, easy to find	Needs a default language fallback
English-as-key	`Start Game`	Readable code, no mapping file for English	Breaks if English text changes

Recommendation: Use semantic keys (MENU_START_GAME) for production; English-as-key only for prototypes or solo projects.

2. Translation Files

CSV Format

The simplest format. First column is the key, subsequent columns are locale codes.

keys,en,cs,de,ja
MENU_START,Start Game,Začít hru,Spiel starten,ゲームスタート
MENU_OPTIONS,Options,Nastavení,Optionen,オプション
