How to find NPC Around?

[tryller]

Im trying to find npc around using monster funciton but it does not work;

if not islocation(3) then
gotolabel("go_shop", "City")

 elseif maround(7, "Sigurd") > 0 then
reachcreature("Sigurd")
end

how can I check if npc is around player?

[Raphael]

local npc = findcreature('Sigurd')

if npc then -- Sigurd is on screen

    -- Do whatever you want

end
