Handles.ArrowCap

public static void ArrowCap(int controlID, Vector3 position, Quaternion rotation, float size);

Parameters

controlID The control ID for the handle.
position The world-space position of the handle's start point.
rotation The rotation of the handle.
size The size of the handle in world-space units.

Description

Draw an arrow like those used by the move tool.

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


Arrow Cap in the Scene View.

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

using UnityEngine;
using UnityEditor;

[CustomEditor( typeof( DummyArrowCap ) )]
public class ArrowCapEditor : Editor
{
	public float arrowSize = 1;

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

		Handles.color = Handles.xAxisColor;
		Handles.ArrowCap( 0, t.transform.position, t.transform.rotation * Quaternion.Euler( 0, 90, 0 ), arrowSize );

		Handles.color = Handles.yAxisColor;
		Handles.ArrowCap( 0, t.transform.position, t.transform.rotation * Quaternion.Euler( -90, 0, 0 ), arrowSize );

		Handles.color = Handles.zAxisColor;
		Handles.ArrowCap( 0, t.transform.position, t.transform.rotation, arrowSize );
	}
}

...and attach this script to the object you wish to display the Arrow Caps on.

using UnityEngine;

[ExecuteInEditMode]
public class DummyArrowCap : MonoBehaviour
{
	public void Start( )
	{
		Debug.Log( "I have ArrowCap Handles attached to this transform!" );
	}
}
