Handles.DrawSolidArc

Parameters

Description

Рисует круглый сектор ("кусок пирога") в 3D пространстве.

Solid Arc in the Scene View.

Важно: Используйте HandleUtility.GetHandleSize если вам нужны маркеры постоянного размера.

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

using UnityEngine;
using UnityEditor;

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

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

        Handles.color = Color.blue;
        Handles.Label(t.transform.position + Vector3.up * 2,
            t.transform.position.ToString() + "\nShieldArea: " +
            t.shieldArea.ToString());

        Handles.BeginGUI();
        GUILayout.BeginArea(new Rect(Screen.width - 100, Screen.height - 80, 90, 50));

        if (GUILayout.Button("Reset Area"))
            t.shieldArea = 5;

        GUILayout.EndArea();
        Handles.EndGUI();

        Handles.color = new Color(1, 1, 1, 0.2f);
        Handles.DrawSolidArc(t.transform.position, t.transform.up, -t.transform.right,
            180, t.shieldArea);

        Handles.color = Color.white;
        t.shieldArea = Handles.ScaleValueHandle(t.shieldArea,
                t.transform.position + t.transform.forward * t.shieldArea,
                t.transform.rotation, 1, Handles.ConeCap, 1);
    }
}
