Lua Charge Spell problems

[lordjanemba]

Hello.
So i was trying to make a "charge" spell for knights, to basically teleport you to your target at the cost of mana...

since i admit i dont know how to handle it as a spell with doCombat things, i figured i could make a workaround about it as a talkaction.

local Target = getCreatureTarget(cid)
local TargetPos = getCreaturePosition(Target)

function onSay(cid, words, param)
	if (getPlayerVocation(cid) == 4) then
		doPlayerAddMana(cid, -50)
			doTeleportThing(cid, Targetpos)
		doSendMagicEffect(getCreaturePosition(cid), 10)
	end
end

However it does actually nothing... why is it? or if you could provide me for a solution as a spell i would be grateful.
