GUI Transparency

[Crzyrndm]

With the Unity default GUI skin, how to decrease the transparency of objects using it? Background alpha channel is maxmised (1/opaque) by default, so I'm a little lost as to where the transparency is originating from

[DMagic]

The only way I've been able to do this is by simply replacing the Unity window background texture with something that has lower transparency. Most of the Unity default skin textures are very simple and you can create something to replicate it fairly easily (the Unity skin set is available to download on the Unity store I think, if you want to have it for reference).

Then you have to load these textures and create new GUIstyles using your new textures as a background.

There's probably some really simple way that I'm missing though...

So basically Unity GUI is as awkward as ever...

Thanks for the answer, but it looks like thats going on the shelf for a while...

You can edit the texture directly (well, a copy of it). I do this in ScienceAlert (CreateReadable):

            Texture2D tex = skin.window.normal.background.CreateReadable();
                windowOpacity = value;

                var pixels = tex.GetPixels32();

                for (int i = 0; i < pixels.Length; ++i)
                    pixels[i].a = (byte)(Mathf.Clamp(windowOpacity, 0, 255));

                tex.SetPixels32(pixels); tex.Apply();

                skin.window.onActive.background =
                skin.window.onFocused.background =
                skin.window.onNormal.background =
                skin.window.onHover.background =
                skin.window.active.background =
                skin.window.focused.background =
                skin.window.hover.background =
                skin.window.normal.background = tex;

As DMagic suggested, editing the default skin is a bad plan. Clone it and edit that one instead.

Is it possible to build a whole new GUISkin using Unity and then use that skin in KSP? I mean I can create one in Unity easy enough but I have no idea how I wold bundle the skin and images up and then load them in KSP, if it is even doable.

Shame KSP didn't update to Unity 4.6 - and thus have the new better UI system - with KSP 0.90. Then again I certainly can't blame them for wanting to keep their engine version stable.

Yes it's doable but you have to write it all in code. See an example in MJ https://github.com/MuMech/MechJeb2/blob/master/MechJeb2/GuiUtils.cs#L269

4.6 was released late November, a bit to late to be used. We will most likely have it for the next release, unless 5 is out by then but I doubt that
