C++ For C# Developers: Part 47 – Containers Library Wrapup

Tags: , , ,

We’ve covered all the individual container types, so let’s take a step back and look at the containers library as a whole. A lot of features, like support for range-based for loops and allocator customization, are supported in all container types. Today we’ll take a look at the commonalities between the containers and see what ties them together into a cohesive library.

C++ For C# Developers: Part 40 – Utilities Library

Tags: , , , , ,

Today we’ll continue to explore the C++ Standard Library by delving into its utility classes and functions. These extremely common tools provide us with basics like std::tuple whose C# equivalent is so essential it’s built right into the language.

C++ For C# Developers: Part 21 – Casting and RTTI

Tags: ,

Now that we’ve seen how types are implicitly converted in C++, we can see how they’re explicitly converted by casting. C++ offers a lot more kinds of casts than C# to control the conversion process. One of them—dynamic_cast—introduces the concept of Run-Time Type Information or RTTI, so we’ll go into that today as well.

C++ For C# Developers: Part 18 – Exceptions

Tags: , , , ,

Like C#, C++ also uses exceptions as one of its main error-handling mechanisms. Today we’ll learn all about them: throwing, catching, their impact on destructors, what happens when they go uncaught, and so much more.

Sharing IDisposables

Tags: , , ,

IDisposable is becoming more and more prevalent in Unity. Previously, it was typically only used for I/O types like FileStream. Now it’s used for in-memory types like NativeArray<T> to avoid the garbage collector. Needing to call Dispose manually means we’re explicitly managing memory, just like we’d do in lower-level languages like C++. That comes with some challenges, especially with shared ownership, which we’ll deal with today.

Simple Formula Evaluator Revisited

Tags: , , , , , ,

A couple years ago, I wrote an article showing how to empower game designers with the ability to write simple formulas like PlayerLevel*100+100. These are much more useful than just constants and don’t require any of the complexity of a real programming language. Today we’ll bring it into the Burst-compatible world and also improve its ability to handle more complex formulas.

Throwing Exceptions in Burst-Compiled Jobs

Tags: , ,

Unity’s Burst compiler imposes an interesting subset of C#. The “no managed objects” rule of thumb is not always correct. Today we’ll look at eExceptions, which are managed objects but are partially supported by Burst. What’s allowed and what’s banned? Read on to find out.

Handling Internal Errors

Tags: , , ,

Some errors can be handled and some cannot. Nevertheless, it’s extremely common to see codebases chock-full of ineffective error handling for these unrecoverable issues. The result is a lot of extra code to write, maintain, and test that often serves to make debugging harder. Today’s article shows you how to make debugging internal errors so much easier by effectively writing code to handle them.

C# 6 in IL2CPP

Tags: , , ,

Unity 2018.1 was released last week and with it comes support for C# 6. Today we’ll take a look at the C++ that IL2CPP generates when we use the new features in C# 6. Warning: one of them is buggy and shouldn’t be used.
