Handles.DrawWireArc

파라미터

설명

Draw a circular arc in 3D space.

Wire Arc in the Scene View.

using UnityEditor;
using UnityEngine;
using System.Collections;

//this class should exist somewhere in your project
public class WireArcExample : MonoBehaviour
{
    public float shieldArea;

    // ...other code...
}

// Create a 180 degrees wire arc with a ScaleValueHandle attached to the disc
// that lets you modify the "shieldArea" var in the WireArcExample.js
[CustomEditor(typeof(WireArcExample))]
public class DrawWireArc : Editor
{
    void OnSceneGUI()
    {
        Handles.color = Color.red;
        WireArcExample myObj = (WireArcExample)target;
        Handles.DrawWireArc(myObj.transform.position, myObj.transform.up, -myObj.transform.right, 180, myObj.shieldArea);
        myObj.shieldArea = (float)Handles.ScaleValueHandle(myObj.shieldArea, myObj.transform.position + myObj.transform.forward * myObj.shieldArea, myObj.transform.rotation, 1, Handles.ConeCap, 1);
    }
}

And the script attached to this Handle:

    // WireArcExample.js

    var shieldArea : float = 5;
