CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

This gist lists various C++ 'quick benchmarks' that have been written on quick-bench.com to test/verify various hypotheses. Quick Bench makes use of Google Benchmark.

Reserve in a vector vs not reserve

Cost of data indirection (e.g. direct vs pointer vs pointer-to-pointer)

'Stack vector' vs vector

Cost of using std::function vs lambda and function pointers

I experienced some frustration with lack of other examples on getting select boxes to work on WPF DataGrid.

The first problem I encountered was that combo boxes did not have single-click to edit. That's what the Setters are for.

The next problem was that once I selected an item in a combobox, the combobox would not leave edit mode if I clicked directly into the next row. That's what the LostFocus and GotFocus events fix.

<!-- XAML -->
<DataGridComboBoxColumn
    ItemsSource="{Binding Source=Blah}"

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
