Plugin Troubleshooting

Symptoms and quick fixes when enabling RPGReact in MZ.

No window opens on desktop (NW.js) after packaging

  • Cause: NW.js runtime not included or invalid package.json entry.

  • Fix: Use the packager with desktop runtime bundling, and ensure package.jsonmain is index.html.

    • ./build-package.ps1 -Target windows

    • Provide the runtime via one of: -RuntimePath, deploy.config.json.runtimePath, or RMMZ_RUNTIME_PATH env var.

Game boots but never leaves black screen

  • Cause: React assets not loaded; the plugin waits for ReactSystemReady.

  • Checks:

    • menus/build/.vite/manifest.json exists in your packaged folder

    • menus/shared/types.js exists

    • Plugin parameter manifestPath matches where the manifest actually is

Overrides didn’t run in development

  • Cause: Missing or invalid overrides manifest, or export names don’t match.

  • Checks:

    • js/plugins/rpgreact/overrides.manifest.json exists and contains { "entries": [ { "file", "export" } ] }.

    • Each listed file exists relative to js/plugins/rpgreact/ (custom files under custom/).

    • Each file defines a function whose name matches the export value.

    • Open DevTools and look for: Error evaluating override ... or Exported function ... not found.

Packaging failed when building overrides

  • Cause: esbuild missing or a syntax error produced an invalid concatenation before minification.

  • Fix:

    • Install esbuild (any one of): yarn add -D esbuild (in project root or under menus/) or add esbuild to PATH.

    • Re-run: ./build-package.ps1 -Target windows.

    • The script fails fast with errors like:

      • Missing manifest: js/plugins/rpgreact/overrides.manifest.json

      • Manifest references missing override file: <file>

      • Failed to create minified overrides bundle. Aborting.

    • Address the specific error and try again.

Production runs but overrides don’t execute

  • Cause: The minified bundle loaded, but exported functions were not promoted due to a mismatch in names.

  • Fix:

    • Ensure each manifest export exactly matches the function name defined in that file.

    • Confirm the bundle exists: js/plugins/rpgreact/RPGReact.overrides.min.js in the packaged output.

    • Confirm only the minified bundle is present (individual override sources are intentionally removed).

Overlay shows scrollbars

  • Cause: Overlay sizing/children overflow.

  • Fix: Use position: fixed + inset: 0 and avoid mixing width/height: 100% with inset.

    • Ensure html, body { margin:0 } and consider overflow: hidden on the overlay container.

Plugin commands appear to do nothing

  • Cause: React app not initialized or hidden.

  • Fix: Ensure you called Show React App after boot; check console for asset load errors.

How to gather logs (desktop)

  • Add to package.json:

    • "chromium-args": "--enable-logging --v=1 --remote-debugging-port=9222"

  • Re-run Game.exe and review debug.log next to the executable.
