enable

---

Example

local start, duration = GetSpellCooldown(spellID, BOOKTYPE_SPELL);
if ( start > 0 and duration > 0) then
	Print('Please wait ' .. duration - ( GetTime() - start) .. ' seconds before using this spell.');
else
	Print('Spell is ready.');
end

Result

Retrieves data. Does not (to my knowledge) actually change anything.

"For the Nature's Swiftness spell and posibly other spells that don't start their cooldown timer before they are used up the values retrieved by GetSpellCooldown change over time. The startTime returned is the current time (that this function was called), not the time the spell was cast. The duration is 0.001 not the spell's normal cooldown.

In this way we can use GetSpellCooldown to see if this type of spell is active on the player without having to look at buffs and debuffs."
