Editor / Application / Set State

How to Call

bash
unity-mcp-cli run-tool editor-application-set-state --input '{
  "isPlaying": false,
  "isPaused": false
}'

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

bash
unity-mcp-cli run-tool editor-application-set-state --input-file args.json

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool editor-application-set-state --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.

Input

Name Type Required Description
isPlaying boolean No If true, the 'playmode' will be started. If false, the 'playmode' will be stopped.
isPaused boolean No If true, the 'playmode' will be paused. If false, the 'playmode' will be resumed.
