Question

我是一个非常入门的编码人员，所以请原谅该编码的基本知识。我正在尝试制作一个简单的游戏，在您按下鼠标速度乘数时，您会在鼠标按下时获得积分。目前，我的鼠标速度功能无法正常工作，目前看来是固定变量。如果有人能指出我做错了什么，我将非常感激。抱歉，如果已经有了答案，我搜索了档案，但没有找到任何能回答我问题的东西。

public class UpdateScoreOnMousePress : MonoBehaviour {

    public Text scoreText;
    public int score;

    public Vector3 mouseDelta = Vector3.zero;
    private Vector3 lastPos = Vector3.zero;
    float mouseSpeed;

    float timeToGo = 0.5f;

    //Initialization
    void Start()
    {
        timeToGo = Time.fixedTime;
    }

    void Update()
    {

    }

    void FixedUpdate()
    {
        //Checks if it has been 0.5 seconds since last call
        if (Time.fixedTime > timeToGo)
        {
            //Updates score on mouse down
            scoreText.text = "Score: " + score + (int)mouseSpeed*0.1;

            //Start mousePosition
            if (Input.GetMouseButtonDown(0))
            {
                mouseDelta = Input.mousePosition;
            }

            else if (Input.GetMouseButton(0))
            {
                mouseDelta = Input.mousePosition - lastPos;

                score++;

                //Shows mouse position and magnitude in console
                Debug.Log("delta X : " + mouseDelta.x);
                Debug.Log("delta Y : " + mouseDelta.y);
                Debug.Log("delta distance : " + mouseDelta.magnitude);

                //Updates mousePosition
                lastPos = Input.mousePosition;

                //Updates mouseSpeed
                mouseSpeed = mouseDelta.magnitude / Time.deltaTime;
            }

            //Updates timeToGo
            timeToGo = Time.fixedTime + 0.5f;
        }
    }
}

似乎您正在检查是否按下了鼠标主键两次。从两者

if (Input.GetMouseButtonDown(0))

和

else if (Input.GetMouseButton(0))

此外，您还必须在每次迭代中更新最后的鼠标位置，到目前为止，仅在按下鼠标按钮时才执行此操作，这是不正确的，但是在未按下按钮时必须执行此操作还有。

我相信，如果将其更改为以下代码，则可以修复您的代码：

    void FixedUpdate()
    {
        //Checks if it has been 0.5 seconds since last call
        if (Time.fixedTime > timeToGo)
        {
            //Updates score on mouse down
            scoreText.text = "Score: " + score + (int)mouseSpeed*0.1;    

            if (Input.GetMouseButtonDown(0))
            {

                mouseDelta = Input.mousePosition - lastPos;

                score++;

                //Shows mouse position and magnitude in console
                Debug.Log("delta X : " + mouseDelta.x);
                Debug.Log("delta Y : " + mouseDelta.y);
                Debug.Log("delta distance : " + mouseDelta.magnitude);

                //Updates mouseSpeed
                mouseSpeed = mouseDelta.magnitude / Time.deltaTime;
            }
            lastPos = Input.mousePosition;
            //Updates timeToGo
            timeToGo = Time.fixedTime + 0.5f;
        }
    }

这不能解决基于移动距离来分配分数的问题，但是您应该能够通过使用mouseDelta来实现。

感谢大家的建议。这是将来可能需要的任何人的最终工作代码。如果需要，可以调整速度倍增器的值，以及固定更新的调用频率。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class UpdateScoreWhileMousePressed : MonoBehaviour {

    public Vector3 mouseDelta = Vector3.zero;
    private Vector3 lastPos = Vector3.zero;

    public float mouseSpeed;

    public Text scoretext;
    public int score;

    public float timeToGo;

    // Use this for initialization
    void Start () {

        timeToGo = Time.fixedTime;
        mouseDelta = Input.mousePosition;
        lastPos = Input.mousePosition;

    }

    // Update is called once per frame
    void Update () {



    }

    // Update is called every 0.2 seconds
    private void FixedUpdate()
    {
        if(Time.fixedTime > timeToGo)
        {

            //Update mouseDelta
            mouseDelta = Input.mousePosition - lastPos;

            //Calculate mouseSpeed
            mouseSpeed = mouseDelta.magnitude / Time.deltaTime;

            scoretext.text = "Score: " + score;

            Debug.Log("Speed: " + mouseSpeed);
            Debug.Log("Score: " + score);

            //If the mouse is being pressed the score will increase by 1 every call
            if (Input.GetMouseButton(0))
            {

                if(mouseSpeed <= 1000)
                {
                    score += 1;
                }

                //And receive multipliers for faster speed
                else if(mouseSpeed > 1000 & mouseSpeed < 2000)
                {
                    score += 1 * 2;
                }

                else if(mouseSpeed >= 2000 & mouseSpeed < 4000)
                {
                    score += 1 * 3;
                }

                else if(mouseSpeed >=4000 & mouseSpeed < 8000)
                {
                    score += 1 * 4;
                }

                else if(mouseSpeed >= 8000)
                {
                    score += 1 * 5;
                }

            }

            //Update lastPost
            lastPos = Input.mousePosition;

            //Update timeToGo
            timeToGo = Time.fixedTime + 0.2f;
        }


    }

}
