[G0tha]

any toughts how to GetTime() from combat log events?

[crystal_tech]

any toughts how to GetTime() from combat log events?

using API_COMBAT_LOG_EVENT the first param is the time stamp.

so under 'if event == "COMBAT_LOG_EVENT_UNFILTERED" then'
add 'local timestamp = select(1, ...)' thats the gettime when it was casted.

[G0tha]

i meant timestamp is diffrent format than Gettime(), so do i use http://www.wowwiki.com/API_time to do it or http://www.wowwiki.com/API_date?
i am not sure what's timestamp return value. they say it's kinda diffrent, but almost the same from time()

[Numba1stunna1]

I have been looking at both of these data files and I have been trying to figure a way to add it to my rogue pvp profile. I want to track just controlled stuns (such as kidney shot and cheapshot). I want to add something like " if controlled stun DR == nil then return true". Any help?

edit: If anyone knows how to script the DR tracker to apply it to abilities and make the abilities return true of CC if the CC is higher than a specific duration. For instance, something like "if "StunDuration >= 3 then return true" (it will only cast the stun ability if the rotation knows that the stun will be 3 seconds or higher based on diminishing returns). Kinda complicated, and I am new to coding.
