Merchant selling stone, price is 0 and can't be bought

Title: Stone price is 0, buy button is disabled.

Summary: While playing with Raya kingdom, sometimes I have the chance to buy stone which is always very cheap (and I don’t like to mine for it), sometimes it is labeled as low as 0 gold. When that happens, I can’t buy it as all buttons get disabled when the stone is selected.

Steps to reproduce:

  1. Play with Raya (I’m not sure if this also happens with the other kingdom)
  2. Wait for a merchant that sells you stone.
  3. The price varies, if it is 0, you can’t buy it.

Expected Results: Buttons enabled so I can buy it. (if 0/free is not intended, round it up to 1 gold)

Actual Results: Clicking on the buy 1/10/all button does nothing, all disabled.

Hey there @BrunoSupremo, welcome to the Discourse! Thanks for the report. Can you verify if you are running any mods?

In the mods folder there is only the 2 raya smod and radiant and stonehearth smod

OK, thanks for checking. I don’t think trading items are intended to cost less than 1 gold each, as that would make them unbuyable. Going to page @sdee and @yshan to see this when they return from their vacation.

Alright, got it (I think)!

Did some digging, and here is what I have found:

The stonecutter shop is defined in stonecutter_shop.json, which is located in mods\rayyas_children\data\gm\campaigns\trader\arcs\encounters. In that json is the following line:

"overall_price_multiplier": 0.8,

Next, looking at hunk_of_stone.json, that defines a basic stone (located in mods\stonehearth\entities\resources\stone\hunk_of_stone), you can find stone’s value in gold:

"stonehearth:net_worth": {
         "value_in_gold": 1,

Finally, a look at the trading ui (shop_bulletin_dialog.js located in mods\stonehearth\ui\game\bulletin\bulletin_dialog\shop_bulletin_dialog) reveals the following:

_updateBuyButtons: function() {
      var self = this;

      var item = self.$('#buyList').find(".selected");
      var cost = parseInt(item.attr('cost'));

Based on the way JavaScript pareseInt works, it will look for all numbers in the first parameter, up to the first invalid character for the specific number system it is converting to. In this specific case the parameter appears to be "0.8" As there is not a second parameter in the function, it defaults to base 10 (how we humans count). As it is parsing the number to an integer, decimals are not allowed, so a decimal in the function would be an “invalid character,” and thus stop the parser, leaving 0 as the remaining integer.


The story of my entire Java class last semster. Haha

Might need to add a checking statement to make sure all 0 are turned to at least 1. :wink:


Stones only cost “0g” at merchants, which makes it impossible to buy them.

Steps to reproduce:

  1. Play the game and wait for a merchant, which sells ores and stones.
  2. Select the stone and try to buy some.

Expected Results:
You can buy stone and “lose” some of your gold in return, like every other item in game.

Actual Results:
Stones are listed with a price of 0g, which (probably correctly) disables the buying buttons, which makes it impossible to buy stones.

Thanks for the report, This bug has already been posted:

Hope this helps, :slightly_smiling:


I have been counting on the automatic search when you start a new topic, and it didn’t come up, so sorry for the repost… ^^

Don’t worry, better to repost than to have no post about it at all.

Sad to see that it didn’t get fixed yet :frowning:

After they fix the higher priorities ones they will come to this, for sure.

oh… It showed up in the automatic search for me, so I didn’t post this one. Maybe I should have posted in the other to up that one to recent. It only showed up when I was finished writing the thing, which is odd. Not sure how that works.

Anyway, just glad to know someone else noticed that and hopefully when they get quite a few of the major things sorted they can get all these minor ones. :smiley:

i’m pretty sure the auto-search for when you’re creating a new topic takes all the words you currently have and compares it to other posts, so for each word you write it compares it again.

make sense? and i’m probably wrong about that…

Nope, that’s correct…though it does factor the title in as well. The issue we have here is that most of the words we use are similar to most other posts…how many topics on this forum use the word “game” or “Hearthling” or “error/bug”…so it isn’t always perfect.
