what is unity's method for converting a string to an integer?

If you are working with strings, you may find yourself needing to convert a string to an integer. Thankfully, this is a fairly easy process with the help of Unity's Int32 or int.Parse method. Through these methods, you can quickly and easily convert a string representation of a number into an actual number. This article will discuss what these two methods are and how to use them.

The Int32 class is found in Unity's System namespace and can be accessed with the "using System;" statement at the top of your program. This class includes the static methods Parse and TryParse which can be used to easily convert strings into integers.

The Parse method will take in a string representation of a number such as "50", parse it into an int value such as 50, then return this value for further use in your program. This parsing will happen implicitly meaning that no extra steps need to be taken by you to successfully convert the string into an integer value. However, you should do some error checking when using this method as it can throw exceptions if an unparseable string is supplied such as "Hello World" instead of "50".

The TryParse method works similarly but instead it returns a boolean value indicating whether or not the parsing was successful instead of throwing exceptions when there is an error in inputted data. This can be useful when you don't want your code crashing due to invalid user input values being formatted incorrectly when attempting to parse them into integers using Int32 or int.Parse().
