Question

public void CheckForHighScore(){
  finall = PlayerPrefs.GetInt("score");// taking score variable from another script to pass in ScoreBoard

   for (int x = 0; x < highScores.Length; x++){
     if (finall > highScoreValues[x]){ 
       for (int y = highScores.Length - 1; y > x; y--) { //sorting
        highScoreValues[y] = highScoreValues[y - 1];
       }
       highScoreValues[x] = finall;
       DrawScores();
       SaveScore();
       PlayerPrefs.DeleteKey("score");
            break;
        }
    }
}



void DrawScores() { 
    for (int x = 0; x < highScores.Length; x++) {  // just adding score to string
        highScores[x].text = highScoreValues[x].ToString();

    }
}

大家好。如何从ScoreBoard数组中删除重复项？试图将这段代码放在排序循环下，但实际上什么也没发生。我也尝试了其他方法，但是它们无法正常工作。任何帮助表示赞赏。

/*for (int j = 1; j < x; j++)
        {
            if (highScoreValues[j] == highScoreValues[x])
                break;
            else
                highScoreValues[x] = finall;
        }*/

Answer 1

您可以使用linq。如果高分是一个对象，则必须重写Equals和GetHashCode

        public override bool Equals(object obj)
        {
            // Insert the Code to override
        }
        public override int GetHashCode()
        {
            // insert the Code to override
        }

请确保GetHashCode为每个对象返回唯一的整数。这样一来，您可以在此处查看更多信息：Correct way to override Equals() and GetHashCode()

如果highScore是基元，则不需要重写方法。

统一highScore之后，您可以使用以下代码：

var sorted = highScores.OrderByDescending（h => h）.Distinct（）。ToArray（）;

Answer 2

List<*Insert type of score here*> cache = new List<*Insert type of score here*>();
for(int index = 0; index < highScores.Length; ++index)
{
    if(cache.Contains(highScores[index]))
    {
        highScores.RemoveAt(index);
        --index; // Every time you have to remove an item, it will slot the next item
                 // into that index and subtract 1 from highScores length. Thus you 
                 // will have to decriment the index in order to check the item that 
                 // gets pushed into that index of your highScore Array. You many 
                 // need to check the syntax if highScores is not a List. But 
                 // hopefully this helps :)
    }
    else 
    {
        cache.Add(highScores[index]);
    }
}
    }
}
