Check is a string contains text

I want to convert input from a GUI.TextField to numbers (which I have done) but how do I check if it contains text?

Current code

http://pastebin.com/jQZLDFkt (don't know how to format code on Unity forums)

I need a if check to see if the objective_CTextFieldString contains text like 53x = false, 53 = true, x = false.

 

There is .Contains()

but probably you should do the logic some other way.. What do you actually want to accomplish?

 

I wanna increase a number in a variable that affects how the game reacts. Well short an experience system. People earn points and then use those points for xp/other stuff. Any recommendations for some other logic, I'm new to Unity.

 

yeah. Int.parse. or int.tryparse.

Google those two things...they allow you to parse a string and see if the value passed in was an int.

 

TryParse will work. However, I've also found it cumbersome and weird, preferring try-catch with int.Parse:

Code (csharp):

1.  
2. bool containsNonNumberText = false;
3. int numberParsed = -1;
4. try {
5. numberParsed = int.Parse(yourText);
6. }
7. catch {
8. containsNonNumberText = true;
9. }
10.  

 

That seems a lot more cumbersome than just

Code (csharp):

1.  
2. int num;
3. if (int.TryParse(myText, out num))
4. {
5.     DoNumberThings(num);
6. }
7.  

 

Yeah, idk what you're doing with that bool in there...tryparse won't return anything if the text isn't a number...so...not sure why you're doing what you're doing.

 

TryParse returns a bool; if it returns true, it found a valid number, if it returns false, it didn't. If it found a number, it will change the value of the second parameter you feed it, to that number.

I guess cumbersome wasn't really the word, just weird.

 

Looks odd at first but is pretty standard. Conceptually works the same as Dictionary.TryGetValue and Physics.Raycast
