Response Format

All commands return JSON:

json

{
  "status": "success",
  "result": { ... }
}

Or on error:

json

{

Troubleshooting

"No Unity port files found"

•Unity must be running with Bridge Lite installed
•Check ~/.unity-bridge/ for status files

"Connection refused"

•Unity may be recompiling - wait and retry
•Restart Unity if bridge is stuck

"Unknown command"

•Unity needs to recompile after code changes
•Click on Unity window to trigger recompile
