# Handles.DrawSolidArc 绘制实心弧

static function DrawSolidArc (center : Vector3, normal : Vector3, from : Vector3, angle : float, radius : float) : void

### Parameters参数

• center
the center of the dics // 圆的中心
• normal
the normal of the disc // 圆的法线
• from
the direction of the point on the circle circumference, relative to the center, where the arc begins
圆周上点的方向，相对于弧线开始的中心
• angle
the angle of the arc, in degrees // 弧度
the radius of the dics Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
圆的半径，注意：使用HandleUtility.GetHandleSize你可能希望有恒定屏幕大小的控制柄。

Description描述

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

Solid Arc in the Scene View.

``````// Create a 180 degrees wire arc with a ScaleValueHandle attached to the disc
// that lets you modify the "shieldArea" var in the WireArcExample.js
//创建一个180度弧线带有ScaleValueHandle附加到圆
//让你可以在WireArcExample.js修改shieldArea变量

@CustomEditor (SolidArcExample)
class DrawSolidArc extends Editor {
function OnSceneGUI () {
Handles.color = Color(1,1,1,0.2);
Handles.DrawSolidArc(target.transform.position,
target.transform.up,
-target.transform.right,
180,
target.shieldArea);
Handles.color = Color.white;
target.shieldArea =
Handles.ScaleValueHandle(target.shieldArea,
target.transform.position + target.transform.forward*target.shieldArea,
target.transform.rotation,
1,
Handles.ConeCap,
1);
}
}``````

And the script attached to this Handle:

``````// SolidArcExample.js

var shieldArea : float = 5;``````
