Handles.ArrowCap

Parameters

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:

#pragma strict
@CustomEditor(DummyArrowCap)
public class ArrowCapEditor extends Editor {
	public var arrowSize: float = 1;
	function OnSceneGUI() {
		var t: DummyArrowCap = 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);
	}
}

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.

#pragma strict
@ExecuteInEditMode
public class DummyArrowCap extends MonoBehaviour {
	public function Start() {
		Debug.Log("I have ArrowCap Handles attached to this transform!");
	}
}

using UnityEngine;

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