Question Input text converted into int array each time I hit Enter. "If error (letters instead of num)" code?

I have an input field where the player has to put a 4-digit number. Isn't there a way I can write a code for when this error is shown on the Unity debug log? "FormatException: Input string was not in a correct format"

 

Showing your existing code would help.

But you probably want something along the lines of

int.TryParse

.

 

It‘s called exception handling. You enclose the code with try/catch blocks and handle the exceptions in an appropriate way, such as reverting to the previous valid value and alerting the user that the input is invalid.

 

omg thank you so much; worked like a charm!
