I want to fade a dialog I made. I cannot fade the color of it, that makes it really complex as it is multiple elements. I want to fade the alpha. It is in a separate gui file and collection
How do I archive this?

Have you tried doing the following:
gui.set_color(gui.get_node("nodeName"), vmath.vector4(1,1,1,1))
and changing the alpha channel (the last one) to whatever value you wish to have? This can, of course, also be animated using a timer to get a fade effect.
There’s an easier way:
gui.animate(node, gui.PROP_COLOR, vmath.vector3(1,1,1,0), gui.EASING_LINEAR, duration)
All of those really on knowing the color. And I have a box insite the box I want to fade, in a different color, so it’s not really color I want to fade right?
Also is there a way to define colors and stings that I can use for both guidelines colors and text?
Ah, ok, so it’s a colored box node without a texture? You can get the color before fading (and alpha will be inherited by child nodes unless you’ve explicitly unchecked that box):
local color = gui.get_color(node)
color.w = 0
gui.animate(node, gui.PROP_COLOR, color, gui.EASING_LINEAR, duration)
Will this effect things inside the box to? Like text?
Ah. So alpha is somehow linked to color?
Well, yes, it’s the fourth component of RGBA (Red, Green, Red, Alpha).
If you assign a texture to a gui node and leave the color as 1,1,1,1 it means that the image will be displayed with the color values of the image. Set a color of 0,1,1,1 and you’ll eliminate all the red from the image while if you set the color to 1,1,1,0 you set it to completely transparent.
If it’s a box node without a texture the color value decides the actual color of the node, where 1,1,1,1 means white and fully opaque. 1,1,1,0 means white but completely transparent.
