[NPC] trade items

[Allesn]

Hello, could you help me with an NPC that exchanges items? I want him to change life crystal 10 by a pure life energy, or 15 for a flawless crystal ice crystal.
thanks

Use following part in creature say callback:

if msgcontains(msg, 'keyword') then
	if doPlayerRemoveItem(cid, 1234, 10) then
		doPlayerAddItem(cid, 4321, 1)
		selfSay('There, sir.', cid)
	end
end
