It works, but as i said before it has no exit because i havent figured out how to use the Input class. i believe update functions are called atomatically, its threw the SceneManager object. To prove that it works i added a sound effect when its called.

After many hours of stressful debugging i have produced a simple HUD plugin (its a script i know i wrote it, plugin makes sounds like it was simpler then it was)

This is one of the few requests i received from game face.

RMMV has nothing to help you AT ALL with syntax errors and most often then not it will just go on pretending the plugin isn't even there if it detects an error but doesn't know how to tell you what error it really is, or even a line number it was found on in the file....

"console.log()" does NOT work you have to use "throw new Error()" instead and that STOPS everything to where you have to reboot the game again. You could also try to use audio cues like "SoundManager.playOk()" to LITERALLY hear if the script has gotten to certain parts (for intense checking if the window was added into the Scene base window manager). To sum it up, debugging scripts/plugins in RMMV looks like a futile effort.

All i've been using to write the code is Notepad + and it just colors key words. If anyone knows of a freeware java script compiler/ code checker, please inform me of it. :p
