Use an event script with a tag and check event.dst

Hi admin,

is it also possible to run a script on scheduled en just check at that moment?
to check what adres did chanced last?
I only want run the script on 11pm.
so i think it is better to just check that time.

Use this:

Code:

tagobjs = grp.tag('tag_name')
maxtime = 0

for _, tagobj in ipairs(tagobjs) do
  updtime = tonumber(tagobj.updatetime) or 0
  if updtime > maxtime then
    obj = tagobj
    maxtime = updtime
  end
end

log(obj)

Thanks admin, it looks like it is working.

Just curious to understand better scripts.

Why is this part of script need for?

Code:

  if updtime > maxtime then

changing the maxtime, doesnt look do anyting.
and why doesnt work

Code:

log(tagobj)

for me it looks like its the same as 'log(obj)' , but it isn't?

[admin]

maxtime stores the maximum update time, it is changed when an object with a larger update time is found. Another option would be to sort the tagged object table by the updatetime field and use the first element of the table.
tagobj is a local variable and it's only visible inside the for loop.
