WINTERLX'S PROFILE

The way it handles selling price is probably a different function entirely. Like, in VX Ace, it's...

class Scene_Shop < Scene_MenuBase
  def selling_price
    @item.price / 2
  end
end

...right here. How that translates to MV, though, I have no idea! My guess would be the the location of the processing isn't terribly much changed. As for what to change it to, I can't really say for sure off the top of my head. Like, the logic in my head is telling me that, if the good in question has a custom price, it should use (half of?) that, and if it does not, use the standard price. However, how to refer to that custom price is what's not coming to me at the moment.


*Edit: The override I did in Myriad Cypher was...

class Scene_Shop < Scene_MenuBase
  def selling_price
    if @buy_window.price(@item) != nil
      @buy_window.price(@item)
    else
      @item.price
    end
  end
end

...this. So, I figure it should be somewhat similar for MV, depending on what the function-call is for obtaining the buy-price.

Glad you got your system working :)

author=Craze
and now you've broken the barrier and are ready to fiddle with scripts for the rest of your gam mak career :)

Thank you all for your support! I hope to have a working prototype for the game's mechanic and story by the end of the month.

Alright!

Solved my issue: I changed my unknown by:

$gameVariables.value(x)

so the codes looks like:

 
var goods = 
[ 
[ 0, 1, 1, $gameVariables.value(1) ], 
[ 0, 2, 1, $gameVariables.value(2) ] 
] 
SceneManager.push(Scene_Shop); 
SceneManager.prepareNextScene(goods, false);

and then created an event to set what x should be equal as, and now I can dynamically modify the price while in-game!

Thank you very much!

I'll give updates about the game development, now that I have the foundation for the store set up.

When you want to know what code is run for a certain event command, a good place to start is the Game_Interpreter. All your game's code is under the "js" directory, and the interpreter code is defined in "rpg_objects.js".

If we search that file for "Shop" we find this is the code that gets run when an event opens the shop menu:

// Shop Processing
Game_Interpreter.prototype.command302 = function() {
    if (!$gameParty.inBattle()) {
        var goods = [this._params];
        while (this.nextEventCode() === 605) {
            this._index++;
            goods.push(this.currentCommand().parameters);
        }
        SceneManager.push(Scene_Shop);
        SceneManager.prepareNextScene(goods, this._params[4]);
    }
    return true;
};

We can call similar code in a script event, and provide our custom "goods" for the shop. The format for the "goods" variable looks like:

goods = [
    // Shop item 1 (item 12 with a custom price of 400G)
    [
        0, // Item type: 0 for item, 1 for weapon, 2 for armor
        12, // id from database
        1, // A value of 1 means use a custom price
        400 // Custom price value
    ],
    // Shop item 2 (armor 30 with a custom price of 800G)
    [
        2,
        30,
        1,
        800
    ]
]

To put it all together we can create a script command inside an event with the code:

var goods = [
    [ 0, 12, 1, 400 ],
    [ 2, 30, 1, 800 ]
]

SceneManager.push(Scene_Shop);
SceneManager.prepareNextScene(goods, false); // Use 'true' for a purchase only shop

If any of this seems way confusing, taking an intro to JavaScript course online should help.
