how and where should I use the hide&show function offered by MM?

[grasshopper001]

I tried to hide all other modules except the current module, but it seems does not work. I put my codes to hide other modules inside the start function of the current module.

Module.register("MMM-hideOtherModules",{
    defaults:{},
    start:function(){
         setTimeout("shutOtherModule",5000);
         function shutOtherModule(){
             MM.getModules().exceptModule(this).enumerate(function(module){
                 module.hide();
             })
         }
    },
//not important functions
}

Could anyone help me with a sample module to hide other modules? Are there any place to learn about the inner structure of inter-modules communication except the doc?

turn on the developers console with Ctrl-Shift=i, or npm start dev, then you can use the console and sources tabs to see errors in the module.js and also put stops on code and look at the variables

as u found, the MM variable is only available in the module.js

codes&question updated

setTimeout(shutOtherModule(),10000);
                function shutOtherModule(){
                     MM.getModules().exceptModule(this).enumerate(function(module){
                     module.hide();
                     })
                 }

question:
When I put the above codes in start function, the module never hides other modules.
When I put the above codes in notificationReceived function and let MagicMirror do the codes after receiving “DOM_OBJECT_CREATED” notification, It seems that the module shuts down all modules including itself, leaving me with a blank mirror.

@grasshopper001 join me for a bit in discord and we will solve your problem https://forum.magicmirror.builders/topic/9298/magicmirror-hackathon-2018

It seems that MM is not available?
I tried to write shutOtherModule function in node-helper, and MagicMirror told me that

ReferenceError: MM is not defined

How could I get access to MM object? Why my MagicMirror responded me with a blank mirror when the function is called after receiving “DOM_OBJECT_CREATED” notification?

[grasshopper001]

Finally I deleted the node helper, it seems that MM functions does not work in node helper functions.
But the setTimeout function in notificationReceived function still does not work with “DOM_OBJECT_CREATED”.

I use MMM-ModuleScheduler to show or hide modules. It works very simple out of the box.
