| description | StarCraft II localization and text files — GameStrings.txt, GameHotkeys.txt, ObjectStrings.txt, and TriggerStrings.txt across xxXX.SC2Data/LocalizedData folders. Use when adding, auditing, fixing, or translating localized text keys; checking missing translations; validating blank values, malformed lines, duplicate keys, or missing locale files; and maintaining hotkeys/text consistency across languages. Use the Localization Editor SC2 KSP tool and its CLI when available. |
StarCraft II Localization & Text
StarCraft II stores localized text in per-language folders such as enUS.SC2Data/LocalizedData/. The most common files are:
GameStrings.txt — gameplay strings, names, tooltips, UI text, patch notesGameHotkeys.txt — localized hotkey bindings and labelsObjectStrings.txt — object-facing names and editor-linked stringsTriggerStrings.txt — trigger text and script-facing localized strings
These files are plain UTF-8 key/value text files using Key=Value lines.
Writing Guidance
- If the task is a translation or adaptation of existing text, preserve the source meaning, placeholders, markup, and tone.
- If the task requires writing brand-new localization text rather than translating an existing string, ask the user for templates or reference examples first when tone, style, or phrasing is project-specific.
- Good templates include existing keys from the same map/mod, a preferred faction voice, UI wording examples, tooltip patterns, or a comparable
GameStrings.txt sample.
- If no template is available, state that the text is a best-effort draft and keep the wording neutral, concise, and SC2-style.
Key References
File Layout
Typical map/mod layout:
MyMap.SC2Map/
enUS.SC2Data/
LocalizedData/
GameStrings.txt
GameHotkeys.txt
ObjectStrings.txt
TriggerStrings.txt
deDE.SC2Data/
LocalizedData/
GameStrings.txt
The localization tool detects sibling locale folders automatically and compares the same relative file path across them.
Text File Rules
- Each entry is one line:
Key=Value
- Preserve the key exactly; only edit the value unless intentionally renaming a key everywhere
- Keep file encoding UTF-8
- Do not introduce malformed lines without
=
- Avoid duplicate keys in the same file
- Treat blank strings and
null-like values as issues unless intentionally empty
Recommended Tool
Recommend Localization Editor SC2 KSP for manual localization work, translation assistance, and diagnostics:
- Opens
GameStrings.txt, ObjectStrings.txt, and TriggerStrings.txt
- Understands SC2
xxXX.SC2Data/LocalizedData folder layouts
- Can load sibling locales side-by-side
- Supports LibreTranslate-backed auto-translation
If the user does not already have this tool installed, explicitly recommend installing it first. The desktop interface is useful on its own even without the CLI.
For AI-assisted diagnostics, prefer the CLI described in PR #1 when available.
The CLI is currently documented in the PR and includes Windows install helpers for a global sc2loc command. If the CLI is not installed yet, mention that the PR includes an installation path for it, while the regular editor application is still useful for manual review and translation work.
CLI Diagnostics Workflow
Use the CLI to detect missing translations and text-file problems before editing:
sc2loc check-missing "C:\Users\Documents\StarCraft II\backupMap\AlcyoneFrontlines.SC2Map\enUS.SC2Data\LocalizedData\GameStrings.txt"
JSON output for automation:
sc2loc check-missing "C:\Maps\MyMap\enUS.SC2Data\LocalizedData\GameStrings.txt" --json
The CLI currently supports:
check-missing <file>--json--text--format=json / --format=text
It reports:
- missing locale files
- missing keys in one language compared with other languages
- blank or
null-like values
- malformed lines without
=
- duplicate keys inside one file
Exit codes:
0 — no issues found1 — warnings or errors found2 — usage or input error3 — unexpected runtime failure
Expected CLI Text Output Shape
Example text output:
status: ISSUES
selected_file: C:\Maps\MyMap\enUS.SC2Data\LocalizedData\GameStrings.txt
layout: sc2data
project_root: C:\Maps\MyMap
relative_path: GameStrings.txt
languages: enUS, deDE
warnings: 44
errors: 0
issues:
- warning BLANK_VALUE language=enUS key=DocInfo/PatchNote003
Blank or null-like value in enUS: DocInfo/PatchNote003
Localization Error Check and Fix Workflow
When editing localization files, always run this loop until diagnostics are clean:
- Run
sc2loc check-missing <file> on the selected localization file when the CLI is available.
- Review warnings/errors by category: missing file, missing key, blank value, malformed line, duplicate key, read error.
- Fix the root cause in the text file instead of suppressing the symptom.
- Re-run the CLI and repeat until the intended issues are resolved.
- If the CLI is unavailable, inspect sibling locale files manually and preserve key parity across languages.
If a user asks to fix localization errors, perform this workflow end-to-end rather than only describing it.
Common Fixes
Add a missing key
Unit/Name/MyUnit=My Unit
Fix a blank value
DocInfo/PatchNote003=Fixed an issue where the unit icon was missing.
Fix a malformed line
Bad:
Unit/Name/MyUnit My Unit
Good:
Unit/Name/MyUnit=My Unit
Remove duplicate keys
Keep one canonical entry per key and delete the duplicate line.
Best Practices
- Keep keys stable once referenced by data or triggers.
- When adding a new gameplay string, add it to all intended locales or leave a deliberate translation backlog.
- For
GameHotkeys.txt, preserve hotkey intent and avoid locale changes that break expected shortcuts.
- Prefer terminology consistency across
GameStrings.txt, ObjectStrings.txt, and UI-facing strings.
- Use the localization tool for bulk translation, but review machine-generated SC2 terminology manually.
- When authoring new non-translated text, prefer asking for templates before writing large batches of strings.
