Remove Numbers from a String
Hi. I need to remove some numbers from a string.
The string looks something like "XX points", where XX is a number. It can be one or two digits.
I tried things with character arrays and such, but I can't get anything to work. Here's the code I'm working on now (it says that the debug.log returns "array index is out of range" error messages).
if (MainBallPoints != null)
{
string ballvalue = string.Empty;
string currentvalue = MainBallPoints.value.ToString();
for (int i = 0; i < currentvalue.Length; i++)
{
if (((int)currentvalue[i] >= 0) && ((int)currentvalue[i] <= 9))
{
ballvalue += currentvalue[i];
}
}
Debug.Log(ballvalue[1]);
Utility.MainBallScore = int.Parse(ballvalue);
Debug.Log(Utility.MainBallScore);
}
Any advice is very welcome. I also don't feel comfortable casting inside of a for loop, but I'm not sure of a way around that.
Thank you for your time.
There are probably ready functions for this. But one way of doing this could be comparing string to ascii table.
This will return a new string without numbers, and set number itself. I didn't test this, but should work.
int num;
string RemoveNumbers(string text){
string newText = "";
string number = "";
for(int i = 0; i < text.Length; i++){
if ((text[i] < 48) || (text[i] > 57)){ //is a char
newText += text[i];
}
else{ //is number
number += text[i];
}
}
num = int.Parse(number);
return newText;
}
I was about to give something like this but then remembered that there should be a regex out there that does it with line. Also, this needs to be checked since I think Unity uses UTF-16 and not ascii (no ascii for sure) but I would think the first byte is just a bunch of 0 so the 48/57 thingy should do.
Hmm, i have posted this type of solutions before and tested them in unity, worked like a charm.
