public static function Slider(position: Vector3, direction: Vector3, size: float, drawFunc: Handles.DrawCapFunction, snap: float): Vector3;

Parameters

positionThe position of the current point.
directionThe direction of the sliding.
size3D size the size of the handle.
drawFuncThe function to call for doing the actual drawing - by default, it's Handles.ArrowCap, but any function that has the same signature can be used.
snapThe snap value (see Handles.SnapValue).

Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

Description

Make a 3D slider.

This will draw a 3D-draggable handle on the screen. The handle is constrained to sliding along a direction vector in 3D space.


Slider handle in the Scene View.

	// Simple script that creates a Magenta Slide Handle that 
	// points to (0,0,0) nomatter where the target GameObject is located.
	
	@CustomEditor (Slide)
	class SliderHandleJS extends Editor {
		function OnSceneGUI () {
			Handles.color = Color.magenta;
	        target.vectorPoint = Handles.Slider (target.transform.position, 
	      						Vector3.zero - target.transform.position);
	        if (GUI.changed)
	            EditorUtility.SetDirty (target);
	    }
	}

And the script attached to this Handle:

	// Usage: Place this script on the Game Object you want to use the
	// editor-created slide handle.
	
	@script ExecuteInEditMode()
	
	var vectorPoint : Vector3 = Vector3(0,0,0);
	
	function Update() {
		Debug.Log("Looking at: " + vectorPoint);
	}
