Im trying to make a block fade in and out. Why is transparency going to 1.1 and -0.1?
Im new to scripting and am trying to create a sphere that continuously fades in and out. I have it working with this script although the transparency will go up to 1.1 and -0.1 and I cant figure out why. Heres what I have.
sphere = script.Parent
transparency = 0
fadeOut = true
while true do
if transparency <= 0 then
fadeOut = true
elseif transparency >= 1 then
fadeOut = false
end
if fadeOut then
transparency = transparency + 0.1
sphere.Transparency = transparency
else -- fadein
transparency = transparency - 0.1
sphere.Transparency = transparency
end
wait(1)
end

After looking at this, I am not sure of this reason either... I can make a guess that maybe it is because of floating point rounding error. Article
What I can tell you is that there is a better way of doing this. Consider using Tween's to do this:
Here is how you would do your fade thing:
sphere = script.Parent
local goal = {}
goal.Transparency = 1 --Assuming that the original transparency is 0
game:GetService("TweenService"):Create(sphere, TweenInfo.new(1, Enum.EasingStyle.Back, Enum.EasingDirection.In, -1, true), goal)
This should work tho I haven't tested it. I recommend you read this: Tween Service

There's a more efficient way to make it.
sphere = script.Parent --- Make sure this is where the object you want to fade in and out transparency
start = 0
goal = 1
----
sphere.Transparency = start --- Ensure you start from transparency 0
while wait() do
for i = 1,10 do
sphere.Transparency = sphere.Transparency + 0.1
end
for i = 1,10 do
sphere.Transparency = sphere.Transparency - 0.1
end
end
