Practical 2D collision detection – Part 2

On our last article, we made a very simple program that helped us detect when two circles were colliding. However, 2D games are usually much more complex than just circles. I shall now introduce the next shape: the rectangle. By now you probably noticed that, for the screenshots I’m using a program called “Collision Test”. […]

Practical 2D collision detection – Part 1

Collision detection is a fascinating, yet almost entirely overlooked and oversimplified aspect of game making. In my experience making games, I have found that collision detection, and subsequent collision resolving is quite tricky to get right. I would like to share a few practical pointers I find useful, so you can get started with your […]

Faking coroutines in C# – Part 1

I happen to love coroutines. When making games, you sometimes want to start a task that takes some time to complete. Let’s consider a simple task: when a button is pressed, wait for 1 second, play a sound, wait for 1 more second and then play another sound. So let’s consider you have a task […]
