.txt File Bug
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("\n"[0]).ToList();
sr.Close();
}
function OnCollisionEnter (col : Collision) {
var sr = File.OpenText("Assets/XXXXXX/Files/charactersHealth.txt");
fileLines = sr.ReadToEnd().Split("\n"[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, -GameDude
well, what happens is that in the file, it starts out with two lines which has two values. Then when i test the game, every time the character collides with something, 7 blank lines appears after the two values. And it keeps happening and soon i have at least 300 unnecessary blank lines.
By the way, is there any way where i can delete the unnecessary blank lines from the .txt file through the script?
I'm rather bussy now and its kinda late, so I'll get back to you tomorrow, but I belive if you do a null check before writing in the txt file your problem will be solved
Ohh. That makes alot of sense. But how can you do that?
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.
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 (`\n`) 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.
Alright, try this:
function Start () {
var sr = File.OpenText("Assets/XXXXX/Files/charactersHealth.txt");
fileLines = sr.ReadToEnd().Split("\n"[0]).ToList();
sr.Close();
}
function OnCollisionEnter (col : Collision) {
var sr = File.OpenText("Assets/XXXXXX/Files/charactersHealth.txt");
fileLines = sr.ReadToEnd().Split("\n"[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);
}
Uh at this part: catch (Exception e){ throw new Exception(e.ToString()); } What is e?
I get two errors when i inputted the code which are: -Unexpected token: e -Unexpected token: throw
Hahaha wow. At least most of it works. Please just translate the stuff into JS. Thanks
