Lua Spells that teleport player to target

[Helliot1]

Hello, I have a problem here, I saw a spell that teleport you to a player that are in screen, but I'm using OTX3, and get a error when I use this spell

How I can fix it ??

You're trying to call the function getPosByDir that either doesn't exist or isn't visible to that script, check if you have this function anywhere, if not, write it or replace it.
I don't know whether this function that I found in my libs is the same as what that one does, but it appears to fit, try putting it in your libs and using it here instead of getPosByDir

function getPositionByDirection(position, direction, size)
    local n = size or 1
    if(direction == NORTH) then
        position.y = position.y - n
    elseif(direction == SOUTH) then
        position.y = position.y + n
    elseif(direction == WEST) then
        position.x = position.x - n
    elseif(direction == EAST) then
        position.x = position.x + n
    elseif(direction == NORTHWEST) then
        position.y = position.y - n
        position.x = position.x - n
    elseif(direction == NORTHEAST) then
        position.y = position.y - n
        position.x = position.x + n
    elseif(direction == SOUTHWEST) then
        position.y = position.y + n
        position.x = position.x - n
    elseif(direction == SOUTHEAST) then
        position.y = position.y + n
        position.x = position.x + n
    end
    return position
end
