Make GUI Button's size fit texture?

Questions & Answers

Hi, i’m new to Unity and now having some troubles with making GUI stuffs. I want to make a menu consisting of some simple buttons aligned center of the menu. I don’t want to fix the position or size of buttons (like setting it x:20, y:20, w:200, h:50 or something like that). All I want is to make size of the buttons and box and any further controls I may add fit the textures given. By now I only found some examples which use fixed width, height for buttons/boxes. Anyone have a solution for this? Sorry if i’m not making it clear enough, i’m not good at expressing things :frowning:

Just use the texture width and height when you specify the button. Example:

var tex : Texture;

function OnGUI() {
	if (GUI.Button(Rect(50,50,tex.width, tex.height), tex))
		Debug.Log("Button Pressed");
}

Or maybe what you have more in mind is the GUILayout class. You can use GUILayout.Button() instead of GUI.Button().

I get it working with the GUISkin by retrieving the width and height of the button’s texture that I attached in the skin. In details:

GUISkin MenuSkin = (GUISkin)Resources.Load ("MenuSkin");

GUI.skin = MenuSkin;

GUILayout.BeginArea (new Rect (0, 0, Screen.width, Screen.height));

int buttonNormalWidth = MenuSkin.button.normal.background.width;

int buttonNormalHeight = MenuSkin.button.normal.background.height;

GUILayoutOption[] options = {GUILayout.Width(buttonNormalWidth),GUILayout.Height(buttonNormalHeight)};

GUILayout.Button ("Game",options);

GUILayout.EndArea ();

Hope that helps someone :smiley:
