Description

Make a directional scale slider.


Scale slider handle in the Scene View.

	// Increase/decrease a value just by moving the Scale slider Handle
	
	
	@CustomEditor (FreeScale)
	class FreeScaleHandleJS extends Editor {
		function OnSceneGUI () {
	        target.val = Handles.ScaleSlider(target.val, 
	        				target.transform.position, 
	        				Vector3.up, 
	        				Quaternion.identity, 
	        				5, 
	        				HandleUtility.GetHandleSize(target.transform.position));
	        if (GUI.changed)
	            EditorUtility.SetDirty (target);
	    }
	}

And the script attached to this handle:

	// FreeScale.js
	@script ExecuteInEditMode()
	
	var val : float = 1;
	
	function Update () {
		Debug.Log("Value tied to the slider: " + val);
	}
