Descripción

Draw a circular arc in 3D space.

Wire 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(DrawWireArc))]
public class DrawWireArcEditor : Editor
{
    void OnSceneGUI()
    {
        DrawWireArc t = target as DrawWireArc;

        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.DrawWireArc(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 DrawWireArc : MonoBehaviour
{
    public float shieldArea = 5;
}
