Declarative Functional APIs – A.K.A. Abusing Lambda Parameters

Functional APIs are a joy to work with. Not only do they help eliminate certain bug categories, but they tend to be very flexible and reusable. Today I present a technique that has emerged while I was simplifying some lambda based APIs. C++17 makes template meta-programming much more palatable, I dare not imagine what this would look like in C++11. Continue reading “Declarative Functional APIs – A.K.A. Abusing Lambda Parameters”

Simplifying Compile-Time Options With if constexpr

My latest little experiment relates to compile-time options and eliminating preprocessor checks in user code. I’m not a big fan of MACROs, especially when they are simply used to make compile-time branches. I am also not a fan of other techniques used to minimize this problem. With C++17, we now have a beautiful and simple tool that can help remove all these preprocessor checks, if constexpr.

Friendly Data-Oriented Entity-Component Managers

In the past months, I’ve rewritten the entity-component system of my engine pet project about three times. Finally, something that ticks all the boxes has emerged. Today, I’d like to present this architecture. So far it has worked wonders for me, though I wouldn’t guarantee this to scale up to AAA sized projects. I still have much testing to do.

Not Impossible : Storing C++ Virtual Method Pointers in C Callbacks.

A good friend challenged me while we where investigating vtables and various ways to create a reflection system without macros. He stated, “It is impossible to store a virtual method pointer in a C callback”. I decided to prove him wrong. Here, I present the result of this investigation. Continue reading “Not Impossible : Storing C++ Virtual Method Pointers in C Callbacks.”

Game Design Memory Lane – Legacy of Kain: Soul Reaver

I’ve recently started playing old gems, classics, in an effort to further my game design knowledge, ideas and culture. The games I have chosen are completely new to me. It is truly interesting to delve into very old titles, especially when you remove the nostalgia factor. Here I write my thoughts, impressions and lessons learned from some of these games.
