Script Update Or Create

Script / Update or Create

Updates or creates script file with the provided C# code. Does AssetDatabase.Refresh() at the end. Provides compilation error details if the code has syntax errors. Use 'script-read' tool to read existing script files first.

Inputs

• filePath — required .cs path.
• content — C# source. MUST pass ScriptUtils.IsValidCSharpSyntax.
• requestId — required for the processing/delivered-later contract.

Behavior

Creates any missing parent directories, writes the file, then calls AssetDatabase.Refresh and schedules a post-compilation notification so the final response is delivered after Unity finishes the recompile.

How to Call

unity-mcp-cli run-tool script-update-or-create --input '{
  "filePath": "string_value",
  "content": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool script-update-or-create --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool script-update-or-create --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.
