who can me explain what that lua make ''Smart Special Area''

[Tj Script]

Smart Special Area

auto(200)
local avoidance = '250'
if $attacked.id == 0 then
avoidance = '0'
end

foreach settingsentry e 'Cavebot/SpecialAreas' do
setsetting(e, 'Avoidance', avoidance)
end

[ozzix]

that will set all spec areas' avoidance to 0 as soon as you don't attack something
