Different way to format text string

Just a very simple way to (hopefully) improve workflow.

If you have to set a text value / string value that includes other variables instead of typing

string someString = "Hello my name is " + nameVar + " and I am level " + levelVar;

You can also use $ to include inline vars in brackets like this

string someString = $"Hello my name is {nameVar} and I am level {levelVar}";

Personally I really like doing it this way because you don’t have to open and close the string everytime.
Hope it helps someone :slight_smile:


Yes, I’m a big fan of this particular trick. In older versions of Unity, this wasn’t available (as Unity was several versions of C# behind the then current Microsoft standard). It’s still behind the standard, but not quite as far behind. Sam eventually mentions string interpolation in the fourth course in the series.

This is one of the many reason I was glad Unity finally got updated with the C# version, or closer to it. There a so many useful features that enhance the ease / readability of our code.

Still a bit behind… we’re on a subset of 9 in the latest Unity.

That’s Unity 2021.
Roughly Speaking 2019 was C#7; 2020 was C#8; 2021 C#9.
Microsoft I think is still on 11 getting ready to move to 12.
I believe that Unity is planing on supporting .Net 6.0 soon.
