NPC trade sells for custom item (REQUEST)

[tlundin]

Hello! Is it possible to make a NPC sell items for other items instead of gold? Change gold value i guess you can call it...

For example:
I want to sell golden boots for 15 christmas tokens and get the trade window as in a normal NPC seller.

rep++ for help

You have to change your source files responsible for it.

You have to change your source files responsible for it.

and where do i do that? and will it change for only 1 npc? Do you have a link to a guide or something if it's hard?

Maybe you can use the NPC that I made and posted on the NPC boards.

And please notice for the next time to use the right board for requests.

In the end, isn't that the sources should edit?

Add value to a item in items.xml should work just fine.

Add value to a item in items.xml should work just fine.

then it will become like a gold coin? but with higher value? I dont want it to work as an extra alternative coin.
