    @yaginku you cannot add new fields to the "database" files (the ones that exist in the data folder already and that use the $data... names in code) for the very reason you have discovered.

    If you want to add new stuff that gets created as the game is played, put it in the $game... objects instead.

    If you want to create your own data that is unrelated to the data files, you'll need to create your own $data... objects and a corresponding json file that gets set up outside of the engine/editor, and you'll need to update the new game, load game and save game functions to include these.

    If you want to add new data to the existing structures, like actors, classes, states, just use the note box for it, and make your plugin read the notes like many others do. Some databases, such as Tilesets, Animations and Systems, don't have note boxes though so you'll need to go with the previous method.

    My current use case is adding additional message fields to States, so every player character gets a different message when they're hit with the same effect.
    For this, I'd use either the Actor note box, or the States note box.

    This seems like an easy enough question, but I can't find a definitive answer. I want to expand the existing JSON data files with additional fields, to hold additional information about attacks, skills, states, etc., however they are being overwritten immediately on the next save.
    I do have an idea about creating additional "extension" databases and merging them on load, but it seems like a lot of hassle for something so basic. I feel like there should be a simpler answer for what I'm looking for. My current use case is adding additional message fields to States, so every player character gets a different message when they're hit with the same effect.
    Why not store it in a separate JSON file? you could have done something like:
    JSON:
    {
    "MAP001": {
      
    },
    "MAP002": {
      
    },
    "MAP003": {
      
    },
    ...
}
    Simply store any plugin specific data between the brackets. As for the name of the JSON file, just give it the same name as the plugin to make it easier to identify.

    Edit: Ah yes, you could probably also use notetags as well like yanfly.. I guess.

    Okay, I've peeked at a different plugin and noticed the "meta" field. Thanks!

    I wanted to make a separate JSON file and then either reach into it and correlate data by ID, or merge both JSONs on load, but it seemed like a lot of work. I might still go for it and the project progresses, but for now the Notes box is sufficient.

    It really isn't much work. Just a few additions to the DataManager class.

    Is there any way to get the duration of an animation based on its ID in $dataAnimations using RMMZ?

    In RMMV it was as simple as $dataAnimations[animationId].frames.length, but the information isn't as obvious in MZ.

    Hey, guys, I think this question goes here? Since it's just a yes or no question. I'm sorry if it's wrong in advance x'D

    Anyways, I'm wondering if it's possible to make a plugin that allows the full use of non-pixelated tilesets? Not parallex mapping, but actual non-pixelated tilesets.

    My main issue lies with the autotiles' size. They shouldn't be changed for it to work, yeah? So I thought if someone make a plugin that allows for this size change, it could work.

    I have a programmer to do it for me now, but I want to make extra sure before asking them. They're quite new, after all. Gotta save them the headaches.

    I'm still quite unsure whether I want to go with it too. Pixel art is charming and all. But yeah, knowing my options doesn't hurt.

    Thank you : D

    There are already plugins (at least for MV, I don't follow MZ) that allow you to use different dimensions for your map tiles in the game.

    It's a bit of work for you, because the editor can't be changed, so you need to have one version of every tileset at 48x48 to work with in the editor, then a second one at whatever dimensions you choose for display in the game, but it works.

    You should Google it up and see if it works in MZ or has an equivalent before paying someone to code for you.

    I see! Thank you. Good to know :D

    Decided to go with pixels after all. But I'll keep it in mind for future reference ^w^)b

    Hello all, is there a way to seal skills pending on the type of weapon a character is wielding? I tried to use the conditional branches using all the axes to only have ax skills and want to have the swords being able to use only sword skills and so on. However when I play the game to test it, all the skills that are available at the character's level are visible. Any tips or tricks or pointing me into the right direction would be awesome. I also have no idea how to write a script.

    Are you posting in the correct thread? This is for JavaScript questions, but your profile says you use VX Ace, which is Ruby-based.

    Regardless, this is built into the engine - when you're looking at a Skill in the database, on the bottom of the screen there are two drop-down boxes labeled "Required Weapon" - if a character is not wielding one of those weapon types, they can't select the skill to use.

    If that's not what you mean, you should start a separate thread with more details.

    Hello i wanted to ask if its possible to detect if the user closes the game (by closing the exe etc), i tried the method onbeforeunload but it didnt work,
    JavaScript:
    window.addEventListener('beforeunload', function (e) {
  // Cancel the event
  e.preventDefault(); // If you prevent default behavior in Mozilla Firefox prompt will always be shown
  // Chrome requires returnValue to be set
  e.returnValue = '';
});

    I am guessing the function dont works because its made for browsers and not exe but i dont really know if thats the case.

    This is for security reasons i am developing a multiplayer mode and i want my database to know that the user is no more logged in (and for other values) via an ajax call, its all good if the user uses the logout function i created however i need to proof test in case the user uses other methods to exit the game. If there isnt i guess i must create an event in the mysql databse or some other method.

    EDIT

    Ok i think i understand the problem now, the unbeforeunload is not getting trigered because the exiting by the exe dont runs a simple window.close, if i do a window close mannualy the pop up appears, so i need to investigate further to see how the exe works.

    What you're asking goes beyond simple JavaScript, because clicking the X to close a window is a Windows process external to the game.

    Here's the information on how Windows does what you're asking about, you'd have to see if there's some way you can tie this into your game. It might be easier to just manage it on the server side via polling.

    Quick question concerning constructing condition statements:

    Is there a difference between


    if (value > 0 && target.isActor() && user.isEnemy() || user.isActor() && target.isEnemy()) {
    ...
    }

    AND

    if (value > 0 && (target.isActor() && user.isEnemy()) || (user.isActor() && target.isEnemy())) {
    ...
    }

    AND

    if (value > 0 && ((target.isActor() && user.isEnemy()) || (user.isActor() && target.isEnemy()))) {
    ...
    }
    Basically, do brackets inside a condition statement have an effect on how they are evaluated?

    The word you're looking for is parentheses. Brackets are [] and {} are braces. Also, as a tip for next time, I had no idea what you were asking about until I hit Reply, because the yellow color you chose for the extra parentheses doesn't show up against the light background of the forum - bolding or italicizing would've been better :wink:

    The answer to your question is yes. The order of boolean operations functions identically to that in math. The order is NOT -> AND -> OR. Just as in mathematical operations, you can force an operation to have priority by putting it inside parentheses.

    So:
    Code:
    if (a || b && c)
    Will only be true if a is true, or if both b and c are true. Whereas:
    Code:
    if ((a || b) && c)
    Will only be true if c is true, and also either of a or b.

    Ah sorry, I wasn't aware that the yellow would be hard to read on light mode.
    I never touch light mode so I didn't think it would be that bad. As for the parentheses, I was actually quickly looking up the word beforehand, but for some reason I was told that it is brackets.

    I guess the symbol has different names when used in normal writing or in coding.


    But thank you for clearing up my question. I already suspected this would work like that (because why shouldn't it) but I just wanted to make sure. :smile:

    This will make creating intelligent conditions a lot easier.

    Not if it's used correctly - all three of those sets of symbols are used in coding, and they all mean different things, so calling them brackets is just incorrect. For example:
    Parentheses are used to pass arguments to a function.
    Brackets are used to reference the index of an array.
    Braces are used to delineate the contents of a function or conditional section.

    None of those things will work correctly if you use a different one of the symbols, so having the three separate names is necessary.

    Edit: Note that these names are not referenced very often in regular English usage, so there are probably many people who just don't know the correct terms. Even coders, if they didn't have a careful teacher or use an accurate textbook, might never have learned the right words for the symbols they're typing.

    For RPG Maker MV.
    Apologies if this has been asked before. Does anyone know how to change the Actor Positions via a script call with Yanfly's Battle Core? I can do it in the javascript editor, but not in-game. There's a lot of empty space that I'd rather spread my guys out a bit if there's a free slot.

    In the Editor it's referred to as "Home Position X" and "Home Position Y" if that helps.

    How should I check if transfer player event is transferring player to the same map or different map. Cause I don't want some stuff to run when the transfer is occurring when player is just transferring across the same map?

    You shouldn't have to do script calls during the game, you should be able to make the Home X and Home Y plugin parameters account for this if you take into account $gameParty.battleMembers().length in the calculations.

    This isn't a JavaScript question, as it can be done via event commands (Control Variable -> Game Data -> Map ID, do one before and after the transfer, then do a conditional check to see if they're the same).

    But what are the circumstances? You create the Transfer Player events, so how would you not know if it's going to the same map or not?

    I have a plugin that executes some stuff on transfer, but I don't want it to happen when the transfer occurs across the same map.
