public static function DrawAAConvexPolygon(params points: Vector3[]): void;
public static void DrawAAConvexPolygon(params Vector3[] points);

Parameters

points List of points describing the convex polygon.

Description

Draw anti-aliased convex polygon specified with point array.


Arrow drawn in the Scene View.

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; }
