TypeError: game.GameManagerSystem is not a constructor

I am able to run my game fine from my local host, but when I build it and launch index.html, I get the error:

TypeError: game.GameManagerSystem is not a constructor

It is from line 32 in main.js:

game.GameManagerSystemJS.update = new game.GameManagerSystem()._MakeSystemFn();

I cannot figure out what is causing this. Does anyone have some insight?

 

Don't know much about it and haven't encountered this error, but two things I would try if I were you:

• Check if GameManagerSystem inherits (extends) ut.ComponentSystem
  
  
• Check the project's modules (enable all modules just to test if it works, and then disable the ones you don't need one by one).

Besides that, a last resort backup option would be to create a new project and import all your components, systems and stuff and then hope it works again.

 

Thank you.

It does inherit from ut.ComponentSystem.

Check my project's modules? What does that mean?

 

UPD: oh, sorry, I get the real context.

The first question - where you get the listing of the main.js file? As I know when you do release build there is no main.js file.
Do you try to clear browser cache?

If so, please check the existence of .map file in the folder where index.html placed. Please remove this file then relaunch your game again and post the code that is going before the line where throws exception.

 

I am not sure the difference between release build and any other build. The only build option I see is "Build". (Alternatively, to press play via the editor.)

There is a local host I can launch from that is created when I build, and that works correctly.

I guess my main objective is to be able to take the created build and drop it on a website. Perhaps I am building incorrectly?

I see no .map file. The main.js is autogenerated when I build.

What steps should I take when I make a build?

(PS, thank you for your help.)

 

I am very blind. I never clicked on the .utproject. There are all sorts of options in there. Thanks

 

Yes, you're right. "Debug" and "Development" versions of the game require started web server on your target machine.
Release version is fully standalone and portable, so it don't require any web servers and may be just opened in the browser with index.js file.
