Change bar color for Mind Blast CD in Weakauras

[EvilMaddness]

This code will change the color for your Mind Blast Cooldown depending on where you set your Warning Time at. I didn't get any help with this code I basically did trial and error till I was able to get it right. This code should work for Shadow Word: Death cooldown also. Just change the spell name.

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
    local start, duration, enable = GetSpellCooldown("Mind Blast")
    local warning_time = 3
    local progress = start + duration - GetTime()
    if start>0 then
        if progress < warning_time then
            return r2, g2, b2, a2
        end
    end
    return r1,g1,b1, a1
end

To make this work in WeakAuras go to the animations tab, main custom, then go down where the color box is ( this is where you set what color you want for your warning time ) put a check on color type will be custom function and then set the code in the custom function box.

Hi! hope everything is going well for you. So I have been trying to find scripts that will change the color of a bar depending on my targets health. I found things like

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
local player_health = UnitHealth("player")
local red, green, blue = 0,0,0
if player_health > 60 then
red, green, blue = 0,1,0
elseif player_health > 20 then
red, green, blue = 0,1,1
else
red, green, blue = 1,0,0
end
return red, green, blue, 1
end

and tried and tried to make it work without any luck.
Do you think you could help me out? Thank you for your time.

Your code assumes that UnitHealth() returns a percentage. It does not.

[Layback_]

Like Seerah said, UnitHealth("unit") function does not return the percentage, but returns current health of the unit.

Your code would still work and even view-able on low levels, but it gets harder to recognize as the damage and health values get huge on higher levels.

Thus, you will have to do something like this:

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
	local health, healthMax = UnitHealth("player"), UnitHealthMax("player");
	local percentage = health / healthMax * 100;
	local red, green, blue = 0, 0, 0;

	if percentage > 60 then
		red, green, blue = 0, 1, 0;
	elseif percentage > 20 then
		red, green, blue = 0, 1, 1;
	else
		red, green, blue = 1, 0, 0;
	end

	return red, green, blue, 1;
end

Hope this helps
