Handles.Disc 圆形

static function Disc (rotation : Quaternion, position : Vector3, axis : Vector3, size : float, cutoffPlane : bool, snap : float) : Quaternion

Parameters参数

• position
  The position of disc. //disc的位置
• rotation
  The rotation of disc. //disc的旋转
• axis
  the axis to rotate around // 旋转围绕的轴
• size
  the size of the disc in world space See Also:HandleUtility.GetHandleSize
  在世界空间disc的大小
• cutoffPlane
  if true, only the front-facing half of the circle is draw / draggable. This is useful when you have many overlapping rotation axes (like in the default rotate tool) to avoid clutter. Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
  如果为真，只有圆的前面一半可以被绘制/可拖动，这通常用于当你有许多重叠的旋转轴（就像默认的选择工具）以避免混乱。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

Make a 3D disc that can be dragged with the mouse

制作一个3D圆形，可以被鼠标拖动。

Disc Handle on the Scene View.
场景视图中的圆形控制柄。

// Create a handle to rotate an object over 45 degrees on X and Y axis
//创建一个控制柄来旋转物体，在x和y轴超过45度

@CustomEditor (DiscValueModifier)
class DiscHandle extends Editor {
	function OnSceneGUI () {
		target.rot =
		Handles.Disc(target.rot,
			target.transform.position,
			Vector3(1,1,0),
			5,
			false,
			1);

		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：

// Usage: Place this script on the Game Object you want to modify
// the handle's rot with the disc
//放置这个脚本到你想使用disc修改控制柄的rot的游戏物体
		
@script ExecuteInEditMode()

var rot : Quaternion = Quaternion.identity;

function Update() {
	transform.rotation = rot;
}
