OnPlayerBuy

The player is about to buy from a shop - return false to refuse.

The stock and the purse were checked already: amount is available and the player can pay amount x price. Return false and nothing moves (say why with SendClientMessage); anything else lets the items and the money go. The class is the item’s GUID (GetItemInfo names it).

Syntax

function OnPlayerBuy(pid, shop, class, amount, price)
  -- ...
end

Parameter	Type
pid	number	the buyer
shop	number	the shop
class	string	the item’s class GUID
amount	number	how many
price	number	Groschen a piece

Returns

false refuses the purchase; anything else (or nothing) lets it through

Example

-- one sword per customer
function OnPlayerBuy(pid, shop, class, amount, price)
  local info = GetItemInfo(class)
  if info and info.category == "MeleeWeapon" and (GetPlayerData(pid, "swords") or 0) >= 1 then
    SendClientMessage(pid, COLOR_RED, "One blade is enough for you.")
    return false
  end
  if info and info.category == "MeleeWeapon" then SetPlayerData(pid, "swords", 1) end
end
