Coins

Coin Trader

• Stick × 1
• Gold Ingot x 1
• Gold nugget × 1

Result

• Call Bell × 1

To use the Call Bell you just have to “eat” the item, right click  you’re playing on PC or keep the screen pressed I’d you play in Pocket Edition, doing this the bell will sound and a coin trader appear on the same place that you, once you finished your trades just leave the trader, its presence don’t affect the any entity around, 

Debit Cards

 Debit cards are selled for the coin trader, but you can also use command blocks to give them to the players, this item makes the add-on compatible with scoreboard stores. In first places coins can be converted in score values, to transform a coin in score you must “eat” it, the coin desapears and you get its value on scores, the card can convert this scores back to coins, this work the same like coins, except that the card don’t desapears, you can see how this works on the video below

      Use with scoreboards

You can create scoreboard stores using this add-on, there’s a tutorial about how

Sell ítems:

• Get a command block

• Put 6 command block in line

• In the first one write this command

• In the second one write the messenge that will be displayed if the player doesn’t have enough money using /title

• All the block after the first one must have the their settings set on “Chain” and “Always Active”
• The third block will give the player the selled item if it has enoug money, use this format, I’m selling a diamond Sword for 10 coins

/give @p[tag=buying,scores={coin=”price”..}] “item” “number of items

• The next block remove the coins from the scoreboard, use this format for the command

/scoreboard players remove @p[tag=buying, scores={coin=”price”..}] coin “price”

• The next block overlaps the previous message with a new one if the players buys the item, use /title for this, you can copy the command, this block also must have the “conditional” setting active, this change how the block looks

• The last one removes the tag, just copy the command in the image

At the end all must looks like this

The sistem that I created on this tutorial sells 1 diamond Sword for 10 coins

Buying player’s ítems: Just use the previous machine with a few changes

• Replace the messenge on the second block

• Replace the command of the third block with this format, this takes the item from the player inventory

/clear @p[tag=buying] “item” 1

• Write on the next block the command that gives coins to the player with this format

/scoreboard players add @p[tag=buying] coin “amount_of_coins”

• This command block also must have the “conditional” settings active

• The whole thing looks like this

This second sistem takes 1 diamond Sword from the player inventory and returns 10 coins

On both of the you must activate the first block to buy/sell the item

             Display Sistem

For default the scoreboard value it’s showed on the pause menu, but you can change this using the botones on one side of the box, that are showed in the image

To keep I working even without players nearby this machine uses mysterious command block magic (Also knowed as ticking area) to keep the nearby chunks charged, so if you need move the box to a new location or just wanna delete it use first the boton on one side, of the machine, this delete both, the machine and the ticking area.

And don’t worry, the machine itself won’t cause any lag, other addons like “F3 Bottom” use this too without even say it, just be sure noone builts big farms or lag machines nearby the box.

Customization

• A zip extractor/compressor
• A pixel art editor, I recommend IsoPix
• A text editor, I use Quick Edit
• Install Json Genie (Only if you will edit the trader)

Extract the files

• Download the addon and change its extension to .zip, on mobile devices this can be donde just renaming the file, in PC it’s different depending of your operative sistem

• Extract the . zip file, you’ll get two carpets, one with the textures and another one with the behaviors

Names: First we’ll edit the names of the items and the trader, here  where you use the text editor

• Enter in the resource pack carpet, open the carpet ” text” and find a file called “en_us.lang
• Change the extension to .txt 

• Open the file, the change the name of every item for whatever you want, you can know what are renaming for the id’s

Coin -> id:coin

Coin 2 -> id:coin2

Coin 5 -> id:coin5

Coin 10 -> id:coin10

Coin 20 -> id:coin20

Coin 50 -> id:coin50

Coin 100 -> id:coin100

Debit Card -> id:card

Call Bell -> id: bell

Coin -> id:coin_trader

• The squares are emojis of the coin logo that you can also customize, if for some reason you erase one and you need to paste it back you can copy this ”   “
• You can also use color text, just paste this symbol ” § ” and after it write a number or letter, depending or what you write the text will change, you can see al the combinations here
• Once you changed the names save the file and change the extension back to .lang
• Now to change how the scoreboard display name go to the behavior pack, find the carpets functions and change the extension of “display.mcfuntion” to .txt

• Use the emoji and color text like in ten previous file if you want
• Open the file and change the last part of the command
• Save the file and change the extension back to .mcfunction

Textures

• First create textures for every coin, the card and the trader if you want, the textures for the items must be a 1×1, you can use any size but must be a 1×1

• Replace the original textures in Custom Economy Resource Pack/textures/items with the new ones, keeping the same names

• To edit the emoji download this image
• Create or paste your icon for the emoji on the image over the coin icon, it must feet into the white square, if you wanna make something bigger that a 16×16 pixels use this page to expand the image, the icon must be on the left side of the square

• Erase the non used pixels and save the image with the same name it has

• Replace the original image inside the carpet “font”  for the new one
• In both cases you can just move the files to the carpets, because they have the same name of the original ones the device will ask you if you wanna overwrite them, just say yes

With that you have finished to create your custom coin, unlike the TLOZ add-on that I created you can use this add-on instead of the main one, if you are going to use a scoreboard store with this add-on you can stop here, if not see how customize the trades for the coin trader .

Coin Trader: This can be the harder part to understand because we need to edit the code directly, I know not all knows about json code, that why we’ll use json Genie, it make edit json code A LOT easier, in this case I won’t use images to explain, I made a video instead,I think  the video is enough it has the same explanations, but you can also see the instructions listed below, read them at the same time that you see what I do in the video and you’ll be fine

• First open the app and find the coin trader table file, it’s inside trading/economy_trades
• Go inside “trades” and clone the last one object
• Edit the trades as you want, there’s 3 parta, “wants” define the item or items and their amount that you must give to the trader, “gives” it’s the same thing but with the items that you obtain and “experience reward” defines if the player will get it not xp for that especifice trades
• When definig the items you “quantity” defines the amount of items, maximum 64, and “items” it’s the id.of the items, for this addon the id’s are

Coin -> id:coin

Coin 2 -> id:coin2

Coin 5 -> id:coin5

Coin 10 -> id:coin10

Coin 20 -> id:coin20

Coin 50 -> id:coin50

Coin 100 -> id:coin100

Debit Card -> id:card

Call Bell -> id: bell

• If you wanna make trades with items from other addons you need to know it’s id, you can use the /give command to know or extract the files of the addon use Json Genie yo open their respective files and find it’s id
• Once you finish save the file, find it on the correct carpet and replace the old one with the new one, you must keep the name and location not the file
• On the video I made a trade that gives you 2 of dirt and xp, but you can do whatever you want, sell items for coins and buy other using them

Closing the addon: Once you have finished compress the resource and behavior pack carpets in a .zip file, change the extension back to .mcaddon and export the addon, if you have exported it before delete it from minecraft first, you can see too on the video
