How can I make a command like that above?

/sell [item] [amount] [price]

It would help SO much. I use ZCMD and SSCANF. Thank you SO much everybody.

You can use sscanf to create a command like this, it's pretty simple.

You would have alter it though on how you're doing your items, for example: If you're getting them from an inventory which is numbered then you might sell via the number, but if not then you'd use a string and just type in the name of whatever you are selling.

pawn Код:

if(sscanf(params, "sii", Item, Amount, Price)) SendClientMessage(playerid, COLOR_WHITE, "USAGE: /sell [Item] [Amount] [Price]"); // Items via string

Obviously you'd have to define the 'Item', 'Amount' and 'Price' before the sscanf line, but that's it. Then you'd just implement the code for your items inside of it.

You'll need strdel, and (advanced) sscanf knowledge. Here's an example of mine - Try to make something out of it:
