[vJASS] Resetting an Ability's cooldown

[Sephalo]

I want to do the following but I'm not sure if it's possible:

A unit uses an ability on the ground.
The x and y of the targetted area are called Dat.x and Dat.y.

call GroupEnumUnitsInRange(Dat.g, Dat.x, Dat.y, 130., Bool)
    if FirstOfGroup(Dat.g) == null then
        /// Reset Cooldown and give a yellow text message just like you
        /// would get if you tried to cast the spell on a wrong target.
    endif

Add/remove ability to reset the cooldown. That has side effects but maybe you can live with them. There is no other way to reset single ability's cooldown.

Maker beat me so dont bother reading this if you read makers post, this is totally the same.

call UnitRemoveAbility(..)
call UnitAddAbility(..)

This is one way of resetting cooldown. The other is call UnitResetCooldown(whichunit) but that resets all cooldowns.
I dont know if there is any other way to reset cooldowns.
Also the message is a bit harder, you can use call DisplayTimedTextToPlayer(whichPlayer, x, y, duration, message) but the x and y are resolution dependant I believe. Actually:

Edit: Just tested and it isn't resolution independent, so I won't use it.

in post in http://www.wc3c.net/showthread.php?t=101260 but you can use values that he used, 0.52, 0.96
