按时间得分乘数

Question

这是我制作的乐谱管理器脚本：

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

 public class ScoreManager : MonoBehaviour {

     public Text scoreText;

     public float scoreCount; // What the score is when the scene first loads. I set this as zero.

     public float pointsPerSecond; // Every second, the points increase by THIS amount. Right now it is 100.

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

         scoreCount += pointsPerSecond * Time.deltaTime;

         scoreText.text = "" + Mathf.Round (scoreCount); // It comes out as a float with like 6 decimals; I round to an nice, clean Integer 

     }
 }

我不知道如何解决的问题是：如何制作一个乘数，在比赛 30 秒后将分数乘以二，然后在 1 分钟后将分数乘以三，然后乘以1 分 30 秒后四次，最后，2 分钟后乘以五次？谢谢:)

Answer 1

这是使用 IEnmurator 功能的绝好机会。这些是您可以调用的方法，您可以告诉它们在恢复之前等待一段时间。所以在你的情况下，你可以有一个 IEnumerator 函数，每三十秒乘以你的分数。例如：

public Text scoreText;

public float scoreCount; // What the score is when the scene first loads. I set this as zero.

public float pointsPerSecond; // Every second, the points increase by THIS amount. Right now it is 100.

private int scoreMultiplier = 1;

void Start()
{
    StartCoroutine(MultiplyScore());
}

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

     scoreCount += pointsPerSecond * Time.deltaTime;

     scoreText.text = "" + Mathf.Round (scoreCount); // It comes out as a float with like 6 decimals; I round to an nice, clean Integer 

 }

IEnumerator MultiplyScore()
{
    while(true)
    {
        yield return new WaitForSeconds(30);
        scoreMultiplier++;
        scoreCount *= scoreMultiplier;
    }
}

请注意，如果您只想进行最多 5 次乘法运算，则可以使用得分乘数变量作为 IEnumerator while 循环中的条件，如下所示：

IEnumerator MultiplyScore()
{
    while(scoreMultiplier < 5)
    {
        yield return new WaitForSeconds(30);
        scoreMultiplier++;
        scoreCount *= scoreMultiplier;
    }
}

Answer 2

private float multiplier = 2.0f;
void Start(){
    InvokeRepeating("SetScore", 30f, 30f);
}
void SetScore(){
    score *= multiplier;
    multiplier += 1f;
    if(multiplier > 5.5f) // Added 0.5f margin to avoid issue of float inaccuracy
    {  
        CancelInvoke()
    } 
}

InvokeRepeating设置第一次调用（第二个参数）和频率（第三个参数），在你的情况下是30s，也是30s。然后一旦乘数太大（大于 5），你就取消调用。

如果您的乘数是整数，您可以去掉边距并使用整数。
