Scaling object with GUI

Hi,

I'm new to Unity and trying to scale a cube with the GUI.
I've found this script:

Code (csharp):

1.  
2. /* Using nested Horizontal and Vertical Groups */
3.  
4. var sliderValue = 1.0;
5. var maxSliderValue = 10.0;
6.  
7. function OnGUI()
8. {
9.     // Wrap everything in the designated GUI Area
10.     GUILayout.BeginArea (Rect (0,0,200,60));
11.  
12.     // Begin the singular Horizontal Group
13.     GUILayout.BeginHorizontal();
14.  
15.     // Place a Button normally
16.     if (GUILayout.RepeatButton ("Increase max\nSlider Value"))
17.     {
18.         maxSliderValue += 3.0 * Time.deltaTime;
19.     }
20.  
21.     // Arrange two more Controls vertically beside the Button
22.     GUILayout.BeginVertical();
23.     GUILayout.Box("Slider Value: " + Mathf.Round(sliderValue));
24.     sliderValue = GUILayout.HorizontalSlider (sliderValue, 0.0, maxSliderValue);
25.  
26.     // End the Groups and Area
27.     GUILayout.EndVertical();
28.     GUILayout.EndHorizontal();
29.     GUILayout.EndArea();
30. }
31.  

How do I use the "sliderValue" for scaling e.g. the x-axis of a cube?

I guess it's the update function but I have no idea how to tell the slide to sclae the cube.

Greetings

 

There are several ways to do it. You can put a script on the cube, for example, that queries sliderValue.

Or you could add:

Code (csharp):

1. public var object : GameObject;

In front and then do something like:

Code (csharp):

1.  
2. object.transform.scale.x = sliderValue;
3. object.transform.scale.y = sliderValue;
4. object.transform.scale.z = sliderValue;
5.  

Not sure about the exact syntax. You will also want to performance-optimize this by calling it only when sliderValue actually changed. But you get the idea?
