There already exist items that you can only buy if you meet rep requirements (things like item 30623: [Reservoir Key]). I tried adding such an item to an NPC unrelated to the reputation and it still checked my rep when buying, so I assume any item with a reputation requirement (on the item itself) will have that reputation as a purchasing requirement.

In other words, try just putting a rep requirement on items and it wont let you buy them unless you meet the requirement.

Yeah i understand that, but im using a custom reputation system with reputations that dont exist in WoW, and dont really use the WoW reputation system. Its literally juat comparing two numbers and cancelling the purchase or retracting the item if conditions are not met. But, it looks like its not really possible. Thanks for trying to help anyway dude i appreciate it.

Is there any way to hook into an event for an item purchase?

I'm trying to make a vendor where some items can only be purchased if certain conditions are met. There doesn't seem to be an 'item purchased' hook anywhere, but I'm wondering if anyone has done this in a more hacky way?

Ideally, I'd like to be able to do this:

function itemPurchased(event, player, item)
   local arbitraryCondition = GetPointsFor(player)
   local itemID = item:GetEntry()
   if(itemID == VENDOR_ITEM_1) then
         if(arbitraryCondition >= 3000)then
               return true;
         else
                 player:SendBroadcastMessage("Requires 3000 arbitrary condition points dumbass")
                  return false; (or, like, player:RemoveItem(itemID, 1))
         end
   end
end



Obviously, I'm using LUA. If anyone has any insight on this it would be greatly appreciated. Thanks guys.
