Handles.DrawWireDisc

public static void DrawWireDisc (Vector3 center, Vector3 normal, float radius);

参数

center	圆盘的中心。
normal	圆盘的法线。
radius	圆盘的半径。注意：如果您希望拥有恒定屏幕大小的手柄，请使用 HandleUtility.GetHandleSize。

描述

在 3D 空间中绘制一个平面圆盘的轮廓。

Wire Disc in the Scene View.

// Create a wire disc with a ScaleValueHandle attached to the disc
// that lets you drag the "areaOfEffect" var in the WireDiscExample.js

@CustomEditor (WireDiscExample)
class DrawWireDisc extends Editor {
    function OnSceneGUI () {
        Handles.color = Color.red;
        Handles.DrawWireDisc(target.transform.position, Vector3.up, target.areaOfEffect);

        target.areaOfEffect =
        Handles.ScaleValueHandle(target.areaOfEffect,
                    target.transform.position + Vector3(target.areaOfEffect,0,0),
                    Quaternion.identity,
                    2,
                    Handles.CylinderCap,
                    2);
    }
}

附加到此手柄的脚本：

//WireDiscExample.js

var areaOfEffect : float = 5;
