public static void DrawSolidArc (Vector3 center, Vector3 normal, Vector3 from, float angle, float radius);

Parámetros

center	The center of the circle.
normal	The normal of the circle.
from	The direction of the point on the circumference, relative to the center, where the sector begins.
angle	The angle of the sector, in degrees.
radius	The radius of the circle.

Descripción

Draw a circular sector (pie piece) in 3D space.

Solid Arc in the Scene View.

Note: Use HandleUtility.GetHandleSize if you want the handle to always remain the same size on the screen.

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);
    }
}

...and place this script on the GameObject where you want the arc to appear:

using UnityEngine;

[ExecuteInEditMode]
public class DrawSolidArc : MonoBehaviour
{
    public float shieldArea = 5;
}
