C++ Scripting: Part 13 – Operator Overloading, Indexers, and Type Conversion

Tags: , , ,

Today’s article continues the series by adding support for C++ to call the various overloaded operators and indexers that are written in C#. This includes support for all 24 overloadable operators in C# plus the explicit and implicit type conversion operators. Indexers aren’t quite overloaded operators, but they allow for array-like indexing into C# types so they’re included today. Read on to learn how all this support was implemented in the GitHub project!

C++ Scripting: Part 10 – Full Generics Support

Tags: , , , , , , ,

C# APIs are chock-full of generics. Generic types, generic method parameters, generic return types, generic fields, generic properties, deriving from generic types, and generic constructors. We can find all of these in the Unity and .NET APIs. Some are more frequent than others, but we’re going to need support for all of them to make C++ scripting a viable alternative to C#. Today’s article continues the series by adding just that: support for all of these kinds of generics. Let’s dive into how to use them as well as some bonus items added to the project this week.

Loops With int and uint

Tags: , , , , , , , , ,

AS3 has two integer types: int and uint. In my experience, most AS3 programmers just use int everywhere and ignore uint. This is usually acceptable as the need for unsigned integers is rare compared to their signed counterparts. However, there are significant performance differences between the two. Read on for the impact of uint on your loops. The original version of this article’s performance test contained a small-but-critical error that led to a lot of incorrect analysis and results. This version of the article has been corrected.

Null and Undefined

Tags:

Usually languages just have one way to specify “no value”. Call it null or nil or whatever you’d like, but AS3 and JavaScript have two: null and undefined. Here’s a little bit to help you understand when and why you’ll come across the two as well as some tricky differences between them.
