Описание

Рисует сглаженную линию, указанную массивом точек и шириной.

"Стрелка в окне Scene".

The following example uses DrawAAConvexPolygon to draw an arrow between two objects in the Scene view. To use this example, save the following script in the Assets/Editor folder:

using UnityEngine;
using UnityEditor;

[CustomEditor( typeof( DrawArrow ) )]
public class DrawArrowEditor : Editor
{
	void OnSceneGUI( )
	{
		DrawArrow	t = target as DrawArrow;

		if( t == null || t.From == null || t.To == null )
			return;

		Vector3[]   arrowHead = new Vector3[3];
		Vector3[]   arrowLine = new Vector3[2];
		Vector3		start = t.From.transform.position;
		Vector3		end = t.To.transform.position;

		Vector3		forward = (end - start).normalized;
		Vector3		right = Vector3.Cross( Vector3.up, forward ).normalized;
		float		size = HandleUtility.GetHandleSize( end );
		float		width = size * 0.1f;
		float		height = size * 0.3f;

		arrowHead[0] = end;
		arrowHead[1] = end - forward * height + right * width;
		arrowHead[2] = end - forward * height - right * width;

		arrowLine[0] = start;
		arrowLine[1] = end - forward * height;

		Handles.color = Color.red;
		Handles.DrawAAPolyLine( arrowLine );
		Handles.DrawAAConvexPolygon( arrowHead );
	}
}

...and attach the following script to a GameObject in the Scene. Drag and drop GameObjects onto the From and To inspectors, corresponding to the objects where you would like to see the arrow drawn:

using UnityEngine;


[ExecuteInEditMode]
public class DrawArrow : MonoBehaviour
{
	public GameObject From, To;
}
