The series continues today with our first actual C++ code! Today we’ll start with the absolute fundamentals—primitive types and literals—on which we’ll build through the rest of the series. As basic as this topic sounds, some of it can be pretty shocking when coming from a language like C#.

Unity 2018.3 officially launched last Thursday and with it comes support for the very latest version of C#: 7.3. This includes four new versions—7.0, 7.1, 7.2, and 7.3—so it’s a big upgrade from the C# 6 that we’ve had since 2018.1. Today we’ll begin an article series to learn what happens when we use some of the new features with IL2CPP. We’ll look at the C++ it outputs and even what the C++ compiles to so we know what the CPU will end up executing. Specifically, we’ll focus on the new tuples feature and talk about creating, naming, deconstructing, and comparing them.
Value types like int, structs, and enums seem simple, but much of what we think we know about them just isn’t true. This article explores how value types actually work in C# and uses that knowledge to improve how they’re implemented in the C++ scripting system.
The GitHub project is closing in on supporting all the “must have” features. Today’s article tackles “boxing” and “unboxing” so our C++ game code will be able to convert types like int into an object and then convert an object back into an int. Usually we want to avoid this because it creates garbage for the GC to later collect and ruins type safety, but sometimes an API like Debug.Log insists that we pass it an object. Read on to see how to use boxing and unboxing in C++!
