Spell [TFS 0.X] Exiva spell from newer tfs

[Tofame]

Yo,
I've just downgraded exiva spell (find_person.lua) from TFS 1.4.2 to TFS 0.X (Tested working on TFS 0.4).
Since it's working and it's good to have the script for that I thought I would share.

    if distance ~= DISTANCE_BESIDE then
        description = description .. " " .. directions[direction]
    end

    doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, var.string .. " " .. description .. ".")
    doSendMagicEffect(getPlayerPosition(cid), CONST_ME_MAGIC_BLUE)

end

spells.xml

<instant name="Player Sense" words="Player Sense" lvl="1" mana="0" aggressive="0" params="1" exhaustion="1000" needlearn="0" event="script" value="yoursense.lua"/>

config those spells.xml, but with the above it's Player Sense "name"
