Lua Assassin Spell TFS 1.0

[Codinablack]

I have this spell I tried to use on tfs 1.0 and it seems that the problem is with doTeleportThing() but tfs does have that function. Here is the spell...

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_ASSASSIN)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_NONE)
setCombatFormula(combat, COMBAT_FORMULA_LEVELMAGIC, -1, -10, -1, -20, 5, 5, 1.4, 2.1)

local function delayedTeleport(cid, position)
if(not isCreature(cid)) then return true end
doTeleportThing(cid, position)
return true
end

function onCastSpell(cid, var)
addEvent(delayedTeleport, 500, cid, getCreaturePosition(cid))
doSendMagicEffect(getCreaturePosition(cid), CONST_ME_POFF)
doTeleportThing(cid, getThingPos(variantToNumber(var)), true)
return doCombat(cid, combat, var)
end

Does it require pushMovement? and if so what is pushMovement? and how do I use it correctly?

Use on target, caster disappears and reappears as the assassin animation on target, then reappears back where casted.
