Description 描述

OnMouseDrag is called when the user has clicked on a GUIElement or Collider and is still holding down the mouse.

当用户鼠标在GUIElement或Collider上拖拽时OnMouseDrag被调用 。

OnMouseDrag is called every frame while the mouse is down.

OnMouseDrag在鼠标按下的每一帧被调用。

JavaScript:

// Darken the material color while user holds down the mouse.
// 在用户按下鼠标的过程中材质颜色渐黑
 
function OnMouseDrag () { 
	renderer.material.color -= Color.white * Time.deltaTime; 
} 

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void OnMouseDrag() {
        renderer.material.color -= Color.white * Time.deltaTime;
    }
}

This function is not called on objects that belong to Ignore Raycast layer.

这个函数不会在属于Ignore Raycast的层上调用。

OnMouseDrag can be a co-routine, simply use the yield statement in the function. This event is sent to all scripts attached to the Collider or GUIElement.

OnMouseDrag 可以被作为协同程序，在函数体内使用yield语句，这个事件将发送到所有附在Collider或GUIElement的脚本上。
