JavaScript => public static var mousePosition: Vector3;
C# => public static Vector3 mousePosition;

Description 描述

The current mouse position in pixel coordinates. (Read Only)

在屏幕坐标空间当前鼠标的位置（只读）。

The bottom-left of the screen or window is at (0, 0). The top-right of the screen or window is at (Screen.width, Screen.height).

屏幕或窗口的左下角是坐标系的（0,0）坐标。右上角的坐标是（屏幕宽度值，屏幕高度值）。

JavaScript:

	var particle : GameObject;
	function Update () {
		if (Input.GetButtonDown ("Fire1")) {
			// Construct a ray from the current mouse coordinates
			var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
			if (Physics.Raycast (ray)) {
				// Create a particle if hit
				Instantiate (particle, transform.position, transform.rotation);
			}
		}
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public GameObject particle;
    void Update() {
        if (Input.GetButtonDown("Fire1")) {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray))
                Instantiate(particle, transform.position, transform.rotation) as GameObject;
 
        }
    }
}
