Handles.Slider 滑动柄

static function Slider (position : Vector3, direction : Vector3) : Vector3
static function Slider (position : Vector3, direction : Vector3, size : float, drawFunc : DrawCapFunction, snap : float) : Vector3

Parameters参数

• position
  the position of the current point. // 当前的位置
• direction
  the direction of the sliding. // 滑向的方向。
• float
  3D size the size of the handle - HandleUtility.GetHandleSize (position);
  控制柄的大小
• drawFunc
  the function to call for doing the actual drawing - by default, it's Handles.ArrowCap, but any function that has the same signature can be used. Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
  调用函数来用于实际的绘制，默认是Handles.ArrowCap，但任意函数具有相同的签名可以被使用。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 slider

制作一个3D滑动柄。

This will draw a 3D-draggable handle on the screen. The handle is constrained to sliding along a direction vector in 3D space.

这将会在屏幕上绘制一个可拖动3D滑动柄。该控制柄被约束滑动沿着3D空间的向量方向。

场景视图中的滑动控制柄

// Simple script that creates a Magenta Slide Handle that
// points to (0,0,0) nomatter where the target GameObject is located.
//创建一个洋红滑动控制柄指向(0,0,0)，target物体的位置。
@CustomEditor (Slide)
class SliderHandleJS extends Editor {
	function OnSceneGUI () {
		Handles.color = Color.magenta;
		target.vectorPoint = Handles.Slider (target.vectorPoint,
		Vector3.zero - target.transform.position);
		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 use the
// editor-created slide handle.
//放置这个脚本到游戏物体

@script ExecuteInEditMode()

var vectorPoint : Vector3 = Vector3(0,0,0);

function Update() {
	Debug.Log("Looking at: " + vectorPoint);
}
