Some legal problem about supporting data format in RPG Maker MV

[XenoAmess]

I used to enjoy RMMV(I bought it on steam,full prize), but I found out that I my wish to make a game engine is bigger than making a game... (also, I HATE JAVESCRIPT!)
So I'm making my own game engine no.
And RPG Maker series are so good that I can't help to have a thought to support some data format used in RPG Maker MV, such as how to save maps, how to save events (by the way ,since you do have the [continue loop] event method,why can't I find it in editor...)
I wouldn't read your original codes(actually I tried but , that is javascript and javasript is too awful to read).
In fact I made a lot of experiments to know how the data in your jsons (in folder /data ) are arranged.
And now I do have some clue to do some things.
So I just wonder if I do have the right to support the json data format in my own game engine?
By the way ,I am writing the engine using LWJGL, and planed to sell it on steam for 2 or 3 dollars for commercial use and free to non-commercial use.(and open sourced).
But I think I should ask before I make the support to RMMV json files.
Well I read your liscence and didn't find anything violation to my plan ,but I would ask about it to make sure.
Notice that I don't want to use your resource or codes,but only want to support the format you used to save json.
I think it is good to you too because I have no interest in making editors.I just enjoy writing runtime cores.And even if there be People willing to use my engine, they shall buy RMMV as editor.
I'm happy to know about your ideas.
Notice that I really want to do this. And even finally I cannot earn profit from it, I would do it too.
Or if you prefer to take half of the pure profit it would make and add it to rpg-maker series ( and thus my engine can use your media and graphic resources too),I would be rather happy.

My opinion is if I understand you correctly. I don't think this would be an issue, I mean you're only selling your editor and the developer who uses that editor MUST own RPG Maker MV and the assets in order to use it, correct? Essentially all you're doing is creating a JSON file that matches the same key properties as MV's json files. So your not actually using anything that has to do with MV at all, the only concern I would see is if you promote it specifically as an RPG Maker MV editor and use their assets in your program or for advertising.

On the other hand it sounds like you want to create a whole new RPG game engine? If so then I would say what you're doing is well against the terms as any RPG Maker MV developer cannot use their assets in other game engines, essentially leaving your game engine useless for anything to do with MV, other than export json files of the data.

Spoiler: More personal opinion

As something a bit more personal.... it's kind of silly to create a whole new engine/editor just because you dislike a language, in fact if you dislike JavaScript so much you're better off finding a better game engine that uses the languages you prefer. RPG Maker MV is a product and a damn good one at that, they have the fans, they have the community and they have a solid publisher. If what you're doing is trying to make a new game engine similar to RPG Maker MV then you will have one hell of a time trying to get noticed in the already dominated(By Degica) market. The fact that you won't use Javascript is another one of those things will help you fail, why? Because I believe at least 60% or more of new RMMV users probably picked it up because of Javascript. Just because you hate Javascript does not mean the other hundreads of developers who use RMMV do and that will make things even tougher.

Nope,the user of my engine of cource have no right to use resources (like pictures or musics) in RTP. But they can make resouces by themself to fit in the format,and import it in RMMV, and make their game, and save the jsons, and finally use my engine to run it. So here come back the question: I don't know quite suer if you treat the jsons as assets like png or music you provided in RTP, or just something not so important? Or in other words, can I use it?
This is the question I want to ask.
Thanks.

Actually it is not so hard to write an editor.
I just think it a little waste of time to do so, as there has already been so good an editor, and if I could borrow it, it would be a help.
But if they think it not acceptable then I would just not support that json format , and make an editor by myself.
It's just a time consuming work, but I would do it if needed. OvO

Also, what I want to make is not actually a remake of RMMV, but more like a 2D ARPG engine.But logics like money, items, party menbers are similar.
But as for event system (or entity , other words), I'd like do it in a way more like Unity, but not like RMMV, to make things funnier.
Of course it would never be an RMMV runtime.Why would I create another RMMV runtime if there already exist one...I'm not insane= =

So you want to use MV's code structure to create your own game engine?

Pretty sure they are just asking if they can struct their JSON files the same as RMMV. That way, they could skip all of the work it'd take to create an editor and use those data files within his custom game engine.
