Hey folks,
i'd like to have a function, that calculates the time to die of my current target.
I've found a addon that does the same - but somehow i am to dumb to do it on my own.
Maybe someone has got nothing to do and can help me out? ^^
i'd like to have a function, that calculates the time to die of my current target.
I've found a addon that does the same - but somehow i am to dumb to do it on my own.
Code:
-- VARIABLES
--first lookup percentage
local first_life
local first_life_max
--first time target seen
local first_time
--current
local current_life
local current_time
Code:
--calculate the time to death
local function calculate_time_to_death()
if current_life == 0 then
am("TTD: "..UnitName("target").." is dead!")
if script_running == 1 then
stop_this("target is dead")
end
else
local time_diff = current_time-first_time
local hp_diff = first_life-current_life
if hp_diff > 0 then
-- Rule of three (Dreisatz):
-- If in a given timespan a certain value of damage is done, what timespan is needed to do 100% damage?
-- The longer the timespan the more precise the prediction
-- time_diff/hp_diff = x/first_life_max
-- x = time_diff*first_life_max/hp_diff
local full_time = time_diff*first_life_max/hp_diff
--if unit was not at 100% at first time seen this is very important we need to calculate backwards in time then too
-- second rule of three needed
--if first_life == max life this will be 0 but otherwise a time will be the result
local past_first_time = (first_life_max-first_life)*time_diff/hp_diff
calc_time = first_time-past_first_time+full_time-current_time
--SecondsToTime can only display values >= 1
if calc_time < 1 then
calc_time = 1
end
local time_to_die = SecondsToTime(calc_time)
local fight_length
local dps
if show_dps == 1 then
dps = floor(hp_diff/time_diff)
dps = " (DPS "..dps..")"
else
dps = ""
end
if show_fightlength == 1 then
fight_length = SecondsToTime(full_time)
fight_length = " after "..fight_length
else
fight_length = ""
end
last_string = "TTD: "..UnitName("target").." dies in "..time_to_die..fight_length..dps
am(last_string)
elseif hp_diff < 0 then
--unit has healed, reseting the initial values
first_life = current_life
first_time = current_time
am("TTD: "..UnitName("target").." has healed. :/")
else
if current_life == first_life_max then
--since unit is at full health we can reset the time and hp values
--thus data will be tracked from the point on when the unit starts to loose life
first_life = current_life
first_time = current_time
am("TTD: "..UnitName("target").." is at full health.")
else
--no damage occured in the timespan
--do nothing but wait
end
end
end
