Input.mousePosition

描述

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

Input.mousePosition is a Vector3 for compatibility with functions that have Vector3 arguments. The z component of the Vector3 is always 0.

屏幕或窗口的左下角坐标为 (0, 0)。 屏幕或窗口的右上角坐标为 (Screen.width, Screen.height)。

注意：即使鼠标不在游戏视图中（例如 Cursor.lockState 设置为 CursorLockMode.None 时），Input.mousePosition 也报告鼠标的位置。以窗口模式运行并且不限制光标移动范围时，如果位置值小于 0 或大于屏幕尺寸 (Screen.width,Screen.height)，则说明鼠标光标位于游戏窗口以外。

In the following example, the x and y coordinates of the mouse position are printed when the “Fire1” button is clicked.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Update()
    {
        if (Input.GetButtonDown("Fire1"))
        {
            Vector3 mousePos = Input.mousePosition;
            {
                Debug.Log(mousePos.x);
                Debug.Log(mousePos.y);
            }
        }
    }
}
