Allows you to fade out and fade in the screen with a single line of code. No configuration needed, just install the addon and you can use it.
This will fade the screen to black over 1 second.
You can achieve scene transition with these 3 lines:
The fade methods take these arguments (only the first one is required):
time - time of the fade (in seconds)
color - the color to fade to/from. Black by default
pattern - the fade pattern. See below. Empty string for no pattern (default)
reverse - if using pattern, this will reverse it. Default is false
smooth - if using pattern, this will make it smooth. Default is false
The node comes with 5 patterns: Diagonal, Diamond, GradientHorizontal, GradientVertical, Noise, Swirl. Just type the name of the pattern to use it, e.g. Fade.fade_out(1, Color.black, "Diamond")
You can add custom fade patterns by putting PNG files to "addons/UniversalFade" folder. The name format is: "Pattern<name>.png", where <name> is what you will provide as argument for the method. They should use grayscale colors and they will fade from white to black.
