String.Contains("\n") returns false
Ok, I have a string that has \n in it, but string.Contains("\n") always returns false.
string temp = lp.levelName;
Debug.Log(temp);
Debug.Log("\n" + temp.Contains("\n"));
temp = temp.Replace("\n", "");
Debug.Log("Replace \n " + temp);
nameText.text = temp;
Log output (after a lot of useless info)
MATCH\n3
False
Replace
MATCH\n3
I use
t.levelName = EditorGUILayout.TextField("Level Name", t.levelName);
to enter the level name, so maybe it's doing some strange modifications to the string there.
Edit:
Ok seconds after posting this I find it's a bug with EditorGUILayout.TextField

You need to escape the backslash or use a here-string.
Either of these should work:
Debug.Log(temp.Contains("\\n"));
Debug.Log(temp.Contains(@"\n"));
And it's not a bug - it's how programming languages work - \n means "newline" so you have to tell it in some way that you really want \n - not "newline"
That's not how they work, if I type \\n I want a newline. So if I write \\n in the editor I should expect the same thing as if I wrote that directly in the code. Otherwise you don't have a way to create newlines in the editor, enter just accepts.
I can't agree with you. The editor is a single line field. What's there is the equivalent of an in-string value.
If you want to be able to write newlines in the editor there's a generic way you could hack it in - write a placeholder, like .nl. and then when you start the application, loop through each of the objects and rename them - replacing the .nl. with a newline character.
That is what I had to do, but because I had strings co$$anonymous$$g from different sources it was quite a bit of work. But they should give us a toggle or something, or maybe just a EditorGUILayout.String();
\n is an escaped character, not a string. You can either escape it by using the @ symbol before using a string containing the character....(which is pointless), OR use it as the character it is:
Debug.Log(temp.Contains('\n'));
Notices the single quote, indicating a character type instead of string type.
Does not even compile, Contains expects a string, not a char, and Replace, that is overloaded with char, does not replace it. @ works, but then that's what I was doing.
