RMMV how to make the menu stop triggering Scene_Map.prototype.onMapLoaded ?

[HenriqueBG]

I am working on a game where I can "summon" random heroes.
So I have 6 events on the summon map that changes their sprites based in the summons, which are the random heroes.
After the heroes are displayed, I can interact with them to choose which ones will join the party. I can also interact again to remove it from the party. But once I do it (selfSwitch is turned off), the event's page seems to reset. The sprite goes back to the originally defined on the software, and not the changed from code.

I changed the event's page's charsetsName and charsetIndex on $dataMap. Even though the game loaded the original info, probably directly from the database.

I think I can get over it by making everything in the same page. Making it not change.
But is there a way to load the pages from the variable $dataMap instead of the database? It would be much better.
-----------------------------------
Edit: Just noticed it happens only if i open the menu. It seems to load the map again.
My pluging works inside a Scene_Map.prototype.onMapLoaded.

It's possible to stop the Game from loading when you resume from the menu, but I recommend you to look for something else. Maybe pure eventing here?

Add this as a Plugin:

var loadedMapId;

(function() {
    const alias = DataManager.loadMapData;
    DataManager.loadMapData = function(mapId) {
        if (loadedMapId != mapId)
            alias(mapId);
    loadedMapId = mapId;
    }
})();

Tell me if it works for you

Thanks for the reply!
i got an error:

rpg_managers.js:1949 TypeError: Cannot read property 'bind' of undefined
    at DataManager.loadMapData (rpg_managers.js:109)
    at Function.DataManager.loadMapData (stopMapReloadFromMenu.js:7)

Replace the line

alias(mapId)

with

alias.call(this, mapId)

This is the exact code from my Plugin that does work, when copy-pasting it needs some adjustments, but maybe this helps you understanding what I did.

// Alias
MK.alias.loadMapData = DataManager.loadMapData;
DataManager.loadMapData = function(mapId) {
    if ($dungeonGenerator.mapId != mapId) {
        $dungeonGenerator.leaveRNGArea();
        MK.alias.loadMapData.call(this, mapId);
    }
    // else: do nothing
};

But in the end, I'm not sure if you really want to make a Base function to not do its job in some cases, it has a high chance to raise incompatibilities. In my Plugin, I do a on-the-fly map manipulation, so I really don't want to reload the Map from disk. But still, it's difficult for me to ensure compatibility with other Plugins that alias loadMapData function.

Thanks Aerosys!
I will take a closer look at it. I just want the menu to stop reloading on one map only. not the entire game.
---------------------
Edit:

It works great!
Just in case anyone else comes here in the future:

var loadedMapId;
const dontReload_MapID = 8; //Add this only if you wanna set what map you want to not reload when openning the menu.

const alias = DataManager.loadMapData;
DataManager.loadMapData = function (mapId) {
    
    if (loadedMapId != mapId) {
        alias.call(this, mapId)
    }
    
    if (mapId == dontReload_MapID) { //Remove the IF, in case you want to the script works on all maps
        loadedMapId = mapId;
    }
    
//Thanks Aerosys for the help
}
