GUI enabled/disable

hi all,

its like this i have a form for people to fill (user registration), and this form its on a pop-up window , when i call that window i need the elements on the main gui to be disabled, so i do GUI.enable = false, this part is all fine and working.

in unity documentation:
"Set this value to false to disable all GUI interaction. All controls will be draw semi-transparently, and will not respond to user input."

is there a way to control how much is the semi-transparency? more or less alpha?

thx

 

What you are looking for is probably in the color field of the GuiStyle you're using. Set the 'a' property to the value you want between 0 and 1 and you'll have your alpha where you want it.

 

hi,

thx for sugestion _met44 but it is not the background of the pop-up window i want to change its the buttons that are draw in "main gui".

1ª image no pop_up windo and GUI.enable = true



2º image pop_up windo and GUI.enable = true


i want to be able to control how intence is the gray area. more or less gray

 

If I understand correctly you want to create a modal window, then the method I described will work just fine.

1 - Make a gui.box bigger than the screen size (x = -5, width = screen.width + 10 kinda thing)
2 - before you draw it, set the style color of the box's background to what suits your needs (perhaps a rgba(0, 0, 0, 0.5) or rgba(0.25, 0.25, 0.25, 0.5) will do the trick, the 3 first values are the actual color, setting all 3 to 0 will be black, 1 is white, then the 4th is for the alpha so 0.5 will let what lies behinds pass though at 50%)
3 - Draw you box using your custom style
4 - Draw the popup window

 

Code (csharp):

1. if (whatever) {
2.     GUI.enabled = false;
3.     GUI.color.a = .1;
4. }

first thx for the help guys

draw a black texture the full screen this controls what we let the player see in the background and of course keaping the aspect ratio

Code (csharp):

1.  
2.             GUI.color = new Color(1,1,1,0.85f);
3.             GUI.DrawTexture(new Rect(0,0,Screen.width, Screen.height),textura_preta);
4.             GUI.color = new Color(1,1,1,1);            
5.             GUI.enabled = false;
6.  

before i launch the gui.window i frist reactivate the gui

Code (csharp):

1.  
2.  
3.                GUI.enabled = true;
4.                 GUI.skin = sk_window;
5.                 janela_fazer_login = GUI.Window(0, janela_fazer_login, fazer_loging, "");
6.                 GUI.skin = null;
7.                 GUI.enabled = false;
8.  

after the gui.window is done i disable the gui again
