Blink mechanic and Enemy script not working together with a specific value?

I have made a blink script for my game, and that's all good and it works perfectly, however, there is a thing that is not working, I am using the blink mechanic for make enemies move when you blink so they can snap your neck, but the script doesn't seem to realize when the blink frame's BackgroundTransparency value goes to 0, which takes only 0.15s (I also tried to make it 0.5-1s)

while true do
local Blink = game.StarterGui.BlinkGui.BlinkMeter.BlinkCastFrame.BackgroundTransparency == 0 --the local value

----------------------------

if minply and not beingwatched and canSee2(script.Parent.Parent, minply.Parent) or minply and canSee2(script.Parent.Parent, minply.Parent) and Blink == true then --Blink == true is the part I am talking about, focus on that
if minmag and minmag <= 99999 then
local unit = (script.Parent.Position-minply.Position).unit
unit = Vector3.new(unit.X,0,unit.Z)
script.Parent.CFrame = CFrame.new(script.Parent.Position + (unit*-1), Vector3.new(minply.Position.X, script.Parent.Position.Y, minply.Position.Z))
script.Parent.Slide:Play()
if minmag < 5 and minply.Parent:FindFirstChild("Humanoid") and minply.Parent.Humanoid.Health > 0 then
minply.Parent:FindFirstChild("Humanoid"):TakeDamage(9999)
local SelectedAttackList = {"NeckSnap1", "NeckSnap2", "NeckSnap3"};
local SelectedAttackSound = script.Parent[math.random(1, #SelectedAttackList)];
SelectedAttackSound:Play()end
end
end
Wait(0)
script.Parent.Slide:Pause() --This is the enemy's final script phase

end

When I change the BackgroundTransparency value to 1 (which means you aren't blinking) in the local value, the enemy moves, but when I change it to 0 (what I want, it means you are blinking) it won't work, despite the frame having the correct value (0).

This is the Blink script phase where the Frame becomes transparent with a nice effect instead of going straight dark:

    if Blink == true then
        while (BlinkCast.BackgroundTransparency > 0) do
            wait(0.01)
            BlinkCast.BackgroundTransparency = BlinkCast.BackgroundTransparency - 0.333
        end
        BlinkCast.BackgroundTransparency = 0
        wait(0.15)
        while (BlinkCast.BackgroundTransparency < 1) do
            wait(0.01)
            BlinkCast.BackgroundTransparency = BlinkCast.BackgroundTransparency + 0.333
        end
        BlinkCast.BackgroundTransparency = 1

The local value as I said works perfectly when changing it to ''BlinkCastFrame.BackgroundTransparency == 0'' So I can't seem to find the solution to fix this problem.
