try changing it to number, in your constant.lua in the lib folder you'll see something like this:

CALLBACK_PARAM_TARGETCREATURE = 4

then just switch:

setCombatCallback(combat, 4, "onTargetCreature")

sometimes it works..

Hmm, I think problem is with this

doTeleportThing(target, toPosition, true)

 

because my function is little different

doTeleportThing(target, toPosition)

 

Instead use doTeleportThing can I use this function?

doMoveCreature(cid, direction)

try without the , true in the teleportThing then try replacing with this:

doMoveCreature(target, getDirectionTo(getCreaturePosition(target), toPosition))

When i use

doMoveCreature(target, getDirectionTo(getCreaturePosition(target), toPosition))

I have crash when CONST_ME_POFF "wave" attack monster :/

 

Maybe I have broken this functions:

doTileQueryAdd(from TFS 0.4)

or

getThingPosition(from TFS 0.4)

 

:/

crash in server or in tibia? any errors in console? dunno how to replace doTileQueryAdd but you can change getThingPosition for getCreaturePosition
