Handles.RadiusHandle 半径控制柄

static function RadiusHandle (rotation : Quaternion, position : Vector3, radius : float, handlesOnly : bool) : float
static function RadiusHandle (rotation : Quaternion, position : Vector3, radius : float) : float

Parameters参数

• position
  Center of the handle in 3D space
  在3D空间，控制柄的中心
• rotation
  Orientation of the handle // 控制柄的方向
• radius
  Radius to modify // 修改半径

float - the modified radius Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

返回浮点值，修改的半径。注意：使用Use HandleUtility.GetHandleSize你可能希望有恒定屏幕大小的控制柄。

Description描述

Make a Scene view radius handle

创建一个场景视图半径控制柄。

This will behave like the built-in scale tool

这行为就像内置的缩放工具。

RadiusHandle on the Scene View.
场景视图中的半径控制器

// Simple script that draws and controls a float var on any Game Object that has the
// ColliderRadius.js script attached.
//绘制并控制在任意游戏物体上，带有ColliderRadius.js的浮点变量。
@CustomEditor (ColliderRadius)
class RadiusHandleJS extends Editor {
	function OnSceneGUI () {
		target.areaOfEffect = Handles.RadiusHandle (Quaternion.identity,
		target.transform.position,
		target.areaOfEffect);
		if (GUI.changed)
			EditorUtility.SetDirty (target);
	}
}

And the Script attached to this handle:

该脚本附加到这个控制柄物体：

// Place this script where you want to see the RadiusHandler working on.
//放置这个脚本到你想看到半径控制器的物体。

var areaOfEffect : float = 1;
