Hi guys,

I have a little trouble fixing a command block.

Basically i set up an economy system on my server using command blocks. The idea is that you can sell and buy items at a central bank location. for currency i am using named and differently coloured firework charges.

here is an example of what this looked like:


For selling stuff and thus aquiring coins i used two command blocks with these codes:

/clear @p minecraft_sugar 0 5

/give @p minecraft:firework_charge 0 1 {display:{name:''5p'',Lore:[genuine]}}

this takes 5 sugar from the player and provides them with a 5 pence coin (im using GBP as currency). i have added the lore 'Genuine' to it, so it would be harder to forge.



for buying something i used two commandblocks with these codes:

/clear @p minecraft:firework_charge 0 1 {display:{name:''5p'',Lore:[genuine]}}

/ give @p minecraft:sugar 5 0

this buying point takes a 5p coin and provides the player with 5 sugar.



i know it might not be the most foolproof way of doing it, but i am not very good with codes.
And it worked just fine, until the 1.13 update, when minecraft decided to mess around with the way commandblocks accept codes.

I am now completely at a loss as to how to fix this.
Does anyone know how i can fix this system and what codes i need to use?

Cheers!
