Handles.color

Description

Look up or set the Color of the handles.

Magenta slider that points to 0,0,0.

To use this example, save this script in your Assets/Editor folder:

#pragma strict
@CustomEditor(SliderHandle)
public class SliderHandleEditor extends Editor {
	// allows you to drag a 'look at' point along the X axis
	function OnSceneGUI() {
		var t: SliderHandle = target as SliderHandle;
		// Set the colour of the next handle to be drawn:
		Handles.color = Color.magenta;
		EditorGUI.BeginChangeCheck();
		var lookTarget: Vector3 = Handles.Slider(t.lookTarget, new Vector3(1, 0, 0), 0.25f, Handles.ConeCap, 0.01f);
		if (EditorGUI.EndChangeCheck()) {
			Undo.RecordObject(target, "Changed Slider Look Target");
			t.lookTarget = lookTarget;
			t.Update();
		}
	}
}

using UnityEngine;
using UnityEditor;

[CustomEditor( typeof( SliderHandle ) )]
public class SliderHandleEditor : Editor
{
	// Simple script that creates a Slide Handle that 
	// allows you to drag a 'look at' point along the X axis

	void OnSceneGUI( )
	{
		SliderHandle t = target as SliderHandle;

		// Set the colour of the next handle to be drawn:
		Handles.color = Color.magenta;

		EditorGUI.BeginChangeCheck( );
		Vector3 lookTarget = Handles.Slider(t.lookTarget,  new Vector3(1, 0, 0), 0.25f, Handles.ConeCap, 0.01f);

		if( EditorGUI.EndChangeCheck( ) )
		{
			Undo.RecordObject( target, "Changed Slider Look Target" );
			t.lookTarget = lookTarget;
			t.Update( );
		}
	}

}

...and place this script on the GameObject you wish to place the Slider Handle on.

#pragma strict
@ExecuteInEditMode
public class SliderHandle extends MonoBehaviour {
	public var lookTarget: Vector3 = new Vector3(0, 2, 0);
	public function Update() {
		transform.LookAt(lookTarget);
	}
}

using UnityEngine;

[ExecuteInEditMode]
public class SliderHandle : MonoBehaviour
{
	public Vector3 lookTarget = new Vector3( 0,2,0 );

	public void Update( )
	{
		transform.LookAt( lookTarget );
	}
}
