Some Gui Functions!

Yo, it's me again. Zak. I am going to show you some gui functions and the way of changing them. This will be a short tutorial on GUI. So remember- pay attention!

Creating your own function:
Creating a function of your own can easily be done, you can just do something like...

So, this is a function I made up in a few seconds.
Explanation:
function hover() --Custom function
BLANK--in these blank lines, will be what the script will do when you "hover" over the gui.
BLANK
BLANK
end --Ending the function.
script.Parent.MouseEnter:connect(hover) --script.Parent=the button you will hover over. MouseEnter:connect(hover)= connects the custom function to the mouse enter method.

Now, we'll add some things inside...

Here I have a frame, textbutton and a screengui - obviously! :P
The frame is not visible, so we can make it visible when you hover over it!
Inside the code:

A short video, what it does:

What about other functions?

Now, MouseEnter() is just one method. There is tons of others, and they never stop....
How about an intro? All we need is a frame, a screengui, and a textlabel!!
How about this...
Frame Size= {1, 0, 1, 0}
Frame position= {0, 0, 0, 0}
TextLabel Size = {0, 0, 0, 0}
TextLabel Position = {0.5, 0, 0.5 0}
[Note]: The TextLabel is in the Frame.
The script that is in the frame:

You can just cut out the textstroketransparency if you aren't using TextStroke. :)
What it does:

If you want to delete the background after the text has faded, or even fade the background at the same time, just do this instead of the code above...

wait(3)

for i=0.01, 1, 0.01 do

script.Parent.TextLabel.TextTransparency=0+i

script.Parent.TextLabel.TextStrokeTransparency=0+i

script.Parent.BackgroundTransparency=0+i

wait()

end
