[Help] How to write to json files (data folder) ?

[lordvalinar]

== CONTEXT ==
I am creating a Grid Based Tactical System on the map and I have setup some scripts to write enemy data to put into Game_Troops; however, I do not know how to write it (overwrite) the Troops.json file.

I am not asking for people to do the plugin for me (just wanted to clear that up), I am merely asking what is the code to save the data to the Troops.json file?

(( I understand possibly using JSON.stringify($gameTroop) or JsonEx.stringify($gameTroop) perhaps? Or something with stringify in general )) But after that, I don't know if there's some HTTP or the DeepCopy functions are required, and so on. A little help would be appreciated.

P.S. I also apologize but I didn't know if this goes in here, or in plugin development since I am asking a little help on JS itself - even if the end goal is for the plugin.

I use this method to write and overwrite json, hope it helps:

RPGMakerMV & Node.js Part 1: Reading And Writing Files

Introduction Following up on the Node.js post, we’re going to create our first plugin in RPGMakerMV with Node.js. Now, this post will require some JavaScript knowledge to follow effectively. …

EDIT: Alright tried it and it's a little finnicky... to use this I need to now find a way to get the game's current directory (or else I have to write it in all manually - and that would not be good for other users).

Currently looking in rpg_managers.js to see how they save/retrieve the data\ json files and see if I can get their methods for the directories. Still thank you for this huge help though

I wouldn't write to the Troops.json file at all. That's MV's file, and the moment you do anything in the editor and save, all your changes will be gone. I would create a completely separate file.

Well I won't be using the Troops tab in the database at all. When I have everything setup and running, it will be easy to setup enemies (they're only ever added to an existing Troop (troopId = mapId); think like the PSP game D&D Tactics, or Divinity: Original Sin, etc).

So overwriting Troops won't be a problem. Also problem solved, made a function that now saves to the Data/ folder:

StorageManager.saveDataFile = function(src, json) {
    if (this.isLocalMode()) {
        var data = JSON.stringify(json);
        var fs = require('fs');
        var path = require('path');
        var base = path.dirname(process.mainModule.filename);
        //
        var dirPath = path.join(base, 'data/');
        var filePath = dirPath + src + ".json";
        if (!fs.existsSync(dirPath)) {
            fs.mkdirSync(dirPath);
        }
        fs.writeFileSync(filePath, data);
        console.log("saveDataFile:\n"+data); // DEBUG
    } else {
        // This section isn't complete
        console.log("saveDataFile: Not local");
    }
};

So above example would use:
var troop = {}; // construct the data
StorageManager.saveDataFile('Troops', troop);

If anyone wants the function by itself to construct enemy data (based on event, not battler) I can post that too. (Or wait until I finish the plugin lol)

The entire database is saved every time you make changes, whether you change anything in that tab or not. So even though you're not using the Troops tab, your file will be overwritten.

If you're determining this as the game is played, why do you need to save the data at all?

Oh! Now I see what you mean..

And I'm trying something out as i'm experimenting and trying to create this battle system. I'm trying to convert the normal battle system to on the map (I know other people have done this already, but I'm trying to make my own; hope to improve it, etc etc).

So I figure there's at least a few things that need to be changed:

- BattleManager
- Game_Map
- Game_Troop
- Scene_Battle

Possibly more... still in early development. Since the battle scene is no longer done in its own battle screen, I'm trying to process the events on the map that trigger (currently with Yanfly's proximity activate plugin) that will setup/add the enemy to a singular troop array (troopId = mapId).

Since currently Game_Troops is still using its functions like ".troop()" that gets $dataTroops[this._troopId], I figure I can mess with less overwrites as possible by just overwriting the Troops.json file.

Now the edits will happen -ingame- including cleanup, so I'm not worried about any edits in the engine overwriting it. It happens real-time. So that's why I save the data. However that being said, I think I see your point. I could just localize the data in the script without having to save a json file at all... since it would merely be cleaned out at the end of battle anyways.

EDIT: Any conditionals could be handled by the event's interpreter instead of the troop's as well
