Unity 3D：比较for循环中的数组

我有一个for循环，它可以获得所有＆＃34; chunks＆＃34;在我的场景中获取X，Y和Z坐标，然后将这些坐标及其名称写入文本文件。它适用于所有块。这个for循环位于一个名为saveLoadedChunk的函数中。每分钟调用此函数以保存块。但问题是，当玩家在10分钟前站在同一区域时，它会将相同的块和结果保存到包含所有块的文本文件中，但会多次。我不希望这种情况发生，所以编写了一小段代码，将文本文件的所有块放在一个数组中，并将它们与要保存的块进行比较。如果是这样的话，它又不会再保存这个块。但是在添加一些Debug.Log（）之后它无法正常工作;函数，我发现第20行的if语句总是采用else分支。我不知道为什么，并感谢所有的帮助。

非常感谢，

代码： 

function saveLoadedChunk() {
    var loadedChunks : GameObject[] = FindObjectsOfType(GameObject) as GameObject[];
    var fileName = "C:/Reactor Games/chunks.txt";    

    var fileText = System.IO.File.ReadAllText(fileName);
    var lines = fileText.Split("\n"[0]);

    var dontWrite = false;

    var sw : System.IO.StreamWriter = new System.IO.StreamWriter(fileName, true);
    for (var i = 0; i < loadedChunks.length ; i++) {
        if(loadedChunks[i].name.Substring(0,5) == "Chunk" || loadedChunks[i].name.Substring(0,5) == "_TERR") {
            if(loadedChunks[i].tag != "Player") {
                var xco = loadedChunks[i].transform.position.x;
                var yco = loadedChunks[i].transform.position.y;
                var zco = loadedChunks[i].transform.position.z;
                var stringToWrite = "Chunk (" + xco + ", " + yco + ", " + zco + ")";

                for(var chunkName in lines) {
                    if(chunkName.Equals(stringToWrite)) {
                        Debug.LogError("dontwrite = true");
                        dontWrite = true;
                    }
                    else{
                        dontWrite = false;
                    }
                }

                if(!dontWrite){sw.WriteLine(stringToWrite);}        
            }
        }
    }
    sw.Flush();
    sw.Close();
}

文本文件示例（如何编写文件，不得写两次） 

Chunk (100, 0, -100)
Chunk (100, 0, -50)
Chunk (100, 0, 0)
Chunk (100, 0, 50)
Chunk (100, 0, 100)
Chunk (50, 0, -100)
Chunk (50, 0, 100)
Chunk (0, 0, -100)
Chunk (0, 0, 100)
Chunk (-50, 0, -100)
Chunk (-50, 0, 100)
Chunk (-100, 0, -100)
Chunk (-100, 0, -50)
Chunk (-100, 0, 0)
Chunk (-100, 0, 50)
Chunk (-100, 0, 100)
Chunk (0, 0, -50)
Chunk (0, 0, 50)
Chunk (-50, 0, -50)
Chunk (-50, 0, 0)
Chunk (-50, 0, 50)
Chunk (50, 0, -50)
Chunk (50, 0, 0)
Chunk (50, 0, 50)
Chunk (0, 0, 0)

错误的文本文件示例： 正如您在下面的文本文件中看到的那样，每次saveLoadedChunk（）;都可以看到它反复写入相同的块。函数被调用。

Chunk (0, 0, -100)
Chunk (0, 0, 100)
Chunk (-50, 0, -100)
Chunk (-50, 0, 100)

更新1： 感谢罗伯特，我将代码更改为以下内容。但是由于某种原因，它仍然没有调试dontwrite ...非常感谢帮助，当它工作时我会接受答案+我对每个帮助我的答案都给予了支持。

    function saveLoadedChunk() {
    var loadedChunks : GameObject[] = FindObjectsOfType(GameObject) as GameObject[];
    var fileName = "C:/Reactor Games/chunks.txt";    

    var fileText = System.IO.File.ReadAllText(fileName);
    var lines = fileText.Split("\n"[0]);

    var write = true;

    var sw : System.IO.StreamWriter = new System.IO.StreamWriter(fileName, true);
    for (var i = 0; i < loadedChunks.length ; i++) {
        if(loadedChunks[i].name.Substring(0,5) == "Chunk" || loadedChunks[i].name.Substring(0,5) == "_TERR" || loadedChunks[i].name.Substring(0,5) == "_ACTI") {
            if(loadedChunks[i].tag != "Player") {
                var xco = loadedChunks[i].transform.position.x;
                var yco = loadedChunks[i].transform.position.y;
                var zco = loadedChunks[i].transform.position.z;
                var stringToWrite = "Chunk (" + xco + ", " + yco + ", " + zco + ")";

                write = true;
                for(var chunkName in lines) {
                    if(chunkName.Equals(stringToWrite)) {
                        Debug.LogError("dontwrite = true");
                        write = false;
                        break;
                    }
                }

                if(write){sw.WriteLine(stringToWrite);}     
            }
        }
    }
    sw.Flush();
    sw.Close();
}

这是因为你的for循环在找到匹配时不会转义。只要行中的LAST对象不等于stringToWrite，它就会写入。将代码更改为以下内容：

dontWrite=false;
for(var chunkName in lines) {
    if(chunkName.Equals(stringToWrite)) {
        Debug.LogError("dontwrite = true");
        dontWrite = true;
        break;
    }
}
