Is it possible to declare a null or escaped char in Unityscript
Cannot convert string to char. That's my problem right now. I don't know why it can't, it isn't like it is a terribly difficult to do... but anyway, all I want is this:
var nothin : char = '\0';
That should work but doesn't. My usual workaround for declaring chars is to say
var charX : char = "X"[0];
which will obviously not work in this case. So what will?
Are you using a literal value like in your example? I'm not understanding why the second method won't work for you.
I don't want '0,' I want backslash-zero, which is a null character. I'm trying to filter textfield input so that all special characters are ignored. In the second example, that's picking the first character out of a string; if I tried to say "\0"[0] I would just get the character "\".
I don't think you understand - char values can be represented by interger values. According to this table the value you want is represented by the number 0.
Here's an experiment for you to try out. Look at the table. According to it, decimal value 65 = 'A'. Let's do this:
var c : char = 65;
Debug.Log(c);
What do you get?
Guys, "\0" is a null character. This isn't about literal backslashes or zeroes.
@Eric5h5, did you even read what I said? I said 0 is the integer value for the null character; they are the same. Look at the link I posted. I'm very aware of what the null character is. Loius' answer was just as correct as yours; arguably more correct because it's cleaner.
If neither of you understand, then try the snippet I posted.
"\0" is a single character, even though it looks like two characters. So
var nada = "\0"[0];
is correct. You can't type "\" by itself and get a backslash character, since the backslash is an escape character. In order to actually use "\" as a char, you'd need to do
var backslashChar = "\\"[0];
What's your use case?
How about "var c : char = 0"?
I agree, I've just been confused about what is difficult about what he wants.
