More trigger questions...

[Shoadowshift]

How do i make a unit get damaged by a % of the distance he moves in a certain time, would like it done as he moves not after the timer runs out.
also, i would like this effect only if a unit has a certain buff at the time a certain spell is cast on him. It sounds possible, though i dont no how to make it.
Cheers for any help

Do you mean that he gets damaged each interval that he's moving, or at the end, based on how far he was from his initial location?

local unit u = GetTriggerUnit()
local unit t = GetSpellTargetOrder()
local location l = GetUnitLoc(t)

loop
     exitwhen // I think its GetUnitEffectLevel(t, BUFF_CODE) == 0

     call UnitDamageTarget(u, t, PERCENTAGE * DistanceBetweenPoints(l, GetUnitLoc(t)), false, false, ATTACK_TYPE_SPELLS, DAMAGE_TYPE_UNKNOWN, null)
     // Replace the damage and attack types with w/e you want
     set l = GetUnitLoc(t)
endloop
