NudgeGUIElements

Author: Jonathan Czeck (aarku)

Description

This script provides menu items to nudge the pixelInset of a GUITexture by 1 pixel or 10 pixels. This is useful for positioning user interfaces. It saves time because you don't have to repeatedly perform addition and subtraction on both xMin and xMax or yMin and yMax values.

Usage

Place this script in YourProject/Assets/Editor/NudgeGUITexture.cs and menu items will automatically appear in the Custom menu after it is compiled. Then select a GUITexture using pixel positioning and select one of the Nudge menu items.

Problems

Sometimes the key combinations do not work. It is not clear why. Also, you must coerce Unity to update the display of GUITextures after nudging.

C# - NudgeGUITexture.cs

<csharp>using UnityEngine; using UnityEditor;

public class NudgeGUITexture : ScriptableObject {

   }

   [MenuItem ("Custom/Nudge GUITexture/Left Fast ^#j")]

   {
       Nudge(-10f, 0f);
   }

   {
       Nudge(1f, 0f);
   }

   static void Nudge(float x, float y)
   {
       // this probably could be thought out better
       Object[] objects = Selection.GetFiltered(typeof(GUITexture), SelectionMode.Deep | SelectionMode.Editable);
       
       foreach (GUITexture guiTexture in objects)
       {
           Rect pixelInset = guiTexture.pixelInset;

           pixelInset.xMin += x;
           pixelInset.xMax += x;
           pixelInset.yMin += y;
           pixelInset.yMax += y;

           guiTexture.pixelInset = pixelInset;
       }
   }
