Handles.DrawAAConvexPolygon

Parameters

Description

Рисует сглаженную линию, указанную массивом точек и шириной.

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 GameObjects where you would like to see the arrow drawn:

using UnityEngine;

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