.txt File Bug

Questions & Answers

Hi. I’m working on a game where it reads info from a file and overwrites the file whenever i need it to. For some reason (which i dont know what the reason is), blank lines keep “spawning” in the .txt file. Heres some of the code. I hope this helps:

function Start () { 
    var sr = File.OpenText("Assets/XXXXX/Files/charactersHealth.txt");
    fileLines = sr.ReadToEnd().Split("

"[0]).ToList();
sr.Close();
}

function OnCollisionEnter (col : Collision) {
    var sr = File.OpenText("Assets/XXXXXX/Files/charactersHealth.txt");
    fileLines = sr.ReadToEnd().Split("

"[0]).ToList();
sr.Close();
WriteHealth();
}

function WriteHealth () {   
    
    var ar = fileLines.ToArray();
    
    if (transform.parent.name == "XXXXX") { 
	ar[0] = health.ToString();
    }
    if (transform.parent.name == "XXXX") {
	ar[1] = health.ToString();
    } 
    File.WriteAllLines("Assets/XXXXXX/Files/charactersHealth.txt", ar);
}
// Some personal info is blanked out with X's

Also, other scripts with kind-of the same type of code is accessing the same file as the code above is.

Thanks for your help,

There is no “bug” in a txt file and also not in the File class. Everything works as it should. The problem here is that you use “WriteAllLines” which usually uses windows line endings (CR + LF). Since you split your text manually on LF ( ) the CR (\r) will remain in the text and will be written to the file as additional lines.

The File class has a lot quite useful static functions like File.ReadAllLines() and File.WriteAllLines. I’m not sure why you use a File object to read the file and WriteAllLines to write the file.

So just use File.ReadAllLines() to read the file and everything should be fine.

Ok i figured it out. I used File.WriteLine instead. Hears some of the code:

function WriteHealth () {   
    var ar = fileLines.ToArray();
    var blankArray : String[] = [""];
    
	if (transform.parent.name == "XXXXX") { 
		ar[0] = currentHealth.ToString();
	}
	if (transform.parent.name == "XXXXX") {
		ar[1] = currentHealth.ToString();
	} 
   	var sw : StreamWriter = new StreamWriter("Assets/XXXXXXX/Files/charactersHealth.txt");

    sw.WriteLine(ar[0]);
    sw.WriteLine(ar[1]);

    sw.Flush();
    sw.Close();
}

Now there is only one blank line no matter what. One blank line isn’t that bad.

Alright, try this:

function Start () { 
    var sr = File.OpenText("Assets/XXXXX/Files/charactersHealth.txt");
    fileLines = sr.ReadToEnd().Split("

"[0]).ToList();
sr.Close();
}

function OnCollisionEnter (col : Collision) {
    var sr = File.OpenText("Assets/XXXXXX/Files/charactersHealth.txt");
    fileLines = sr.ReadToEnd().Split("

"[0]).ToList();
sr.Close();
WriteHealth();
}

function WriteHealth () {   

    var ar = fileLines.ToArray();

    if (transform.parent.name == "XXXXX") { 
    ar[0] = health.ToString();
    }
    if (transform.parent.name == "XXXX") {
    ar[1] = health.ToString();
    }
if(ar[o] && ar[1]){
            File.WriteAllLines("Assets/XXXXXX/Files/charactersHealth.txt", ar);
}
