RMMV (MV) Trying to open Shops with dynamic inventory. Help needed in placing items into shops through scripting.

[TheTitan99]

Basically, I want to make a shop that updates its inventory based on variables. Like, as an example, if you are level 1, it has potions. If you're level 2, super potions. Level 3, ultra potions. I would rather not have a million different event commands where I have to manually place all the items in the shop, but instead simply have a simple array of items that I can create, and put that array into the shop.

It feels like it should be simply to do this. I know how to open a shop using script calls. The problem comes to actually giving that shop any inventory. For instance, this code:

var goods = [0,1,2,3];

SceneManager.push(Scene_Shop);
SceneManager.prepareNextScene(goods, false);

Doesn't work! The shop opens fine, and you can sell to your heart's content. But the shop has no items at all.

I tried changing it to this, but to no avail:

var goods = [$dataArmors[2], $dataArmors[3]];

SceneManager.push(Scene_Shop);
SceneManager.prepareNextScene(goods, false);

Once again, there's simply nothing in the shop.

I don't know how to proceed. Any help in formatting how to put items into the store's goods will be super helpful. Once I know the formatting, I think I can do the rest on my own. I just need to know how to, through scripts (or a plugin command), and not events, to populate a shop's inventory.

goods is an array of arrays, where each element has a different meaning:
- The first element of the subarrays is the kind (0 for item, 1 for weapon, 2 for armor)
- The second element is id of the item
- The third element is a flag to indicate whether a custom price should be set
- The last element is the custom price,

so:

var goods = [];

goods.push([0, 1, 0, 0]); // Would push item #1 without a custom price into the goods.
goods.push([1, 2, 1, 50]); // Would push weapon #2 with a custom price of 50 into the goods.

SceneManager.push(Scene_Shop);
SceneManager.prepareNextScene(goods, false);

I hope that helps you.

Thank you very much! This is super helpful, and I think I'll be able to make my systems now.

I think this can probably be closed now. Thanks a bunch!

Just report your first post and let the mods know you got your answer, if you want the thread to be closed.

hime or yanfly had a plugin to hide good until require level or whenever you want
unhide it if it makes easier for you.
