Newb having problems with images in GUI.Box

Hi Everybody,

Just starting out in Unity after years of Director3dness and loving the potential of Unity, but I've hit a bit of a stumbling block. I've been following http://unity3d.com/support/documentation/Components/gui-Basics.html to create buttons, which work fine, but when I try to add an image nothing happens.

My script...

Code (csharp):

1. var bgImage : Texture2D;
2.  
3. function OnGUI(){
4.     GUI.Box(Rect(0,0,256,256),GUIContent("Select a shape",bgImage));
5.     if(GUI.Button(Rect(55,40,80,20),"Box")){
6.         print("Box");
7.     }
8.     if(GUI.Button(Rect(55,70,80,20),"Sphere")){
9.         print("Sphere");
10.     }
11. }
12.  

Now, if I've understood this I assign an image by dragging an image asset from the project window into the default references. It seems to relate bgImage to the image I want to use, but I can't see anything.
The image is a psd 256x256.

Any ideas what I'm doing wrong or any idiot safe tutorials on GUI?

Sorry if this seems dumb.

 

Unless it's an error in the documentation, the GUI.Content structure takes a Texture object and not Texture2D:

http://unity3d.com/support/documentation/ScriptReference/GUIContent.GUIContent.html

 

Didn't seem to make a difference. No image is shown. The text displays, but the image doesn't. I've tried a jpeg and a psd. The JPEG was 32x32, the psd 256x256. I've tried Texture and Texture2D as the var. With and without GUIContent. But nothing.

It seems like it should be pretty straight forward.

 

Not sure why that's not working. (I haven't worked with the GUI.Content constructor)

Another option is to install a custom skin and assign your texture to the GUISTyle of the box in the inspector. (The skins are on the wiki and have been posted in threads here.)

 

Your script worked for me when I tried a 256 x 256 .PNG:

 

I'll be a monkeys uncle... the png worked...

Thanks bigkahuna!

Are there certain filetypes to avoid/prefer for gui?

 

Ah... I may have discovered my error. If I have this right, I need to assicoiate the image with the instance of the script on the gameobject rather than the instanc e of the script in the project window... If that makes sense?

 

Avoid .jpg, but everything else should work. (.jpg will work, but you don't want the quality loss.)

Welcome aboard then.

That does make sense as it's how you do things.
