Whenever you write a level editor or maybe a turn-based game (like chess) it would be of great help having undo and redo functionality at hand. Based on the Game Programming Patterns book from Robert Nystrom I did like to implement an undo/redo history class. The design pattern is based on the Design Patterns book […]

Game Programming Patterns
I recently read Game Programming Patterns from Robert Nystrom one of the best books about programming I’ve ever read. I read the entire book from beginning to end in one go, I couldn’t stop. Normally I use programming books to fall asleep, the design pattern book of the gang of four doesn’t make any exception. […]
Test Driven Development Integration Test
Beside unit tests, it is a good idea to have some integration tests. An integration test only makes sure that the new feature is in place. An integration test does not ponder on edge cases. It’s crucial to keep an integration test as simple as possible. Make the Greeter App Modular The greeter app from […]
Test Driven Development Fixtures
We all tend to write helper classes for testing, which clutters the test code and makes it harder to understand. A test should be like a story that you simply can read from top-down. I like test story better than fixture and I will use story and fixture interchangeable. Why a Story Is More Powerful […]
The Many Deaths of My Stupid Soliders
A sneak peek of our game. My hero shoots the first two enemies. Over and over again. Enjoy
Laughing While Shooting
The little hero starts to laugh when shooting a lot. It is bound to the number of rounds per second to make him start laughing, every weapon has his threshold. Or when he shoots two or more targets in a row. It makes the game more fun. I’m thinking of more little animations like the […]
Test Driven Development Mantra
This is the mantra Think of a piece of code you want to add Write a test which fails because that piece of code is not in place Write that piece of code to make the failing test succeed Refactor the code Refactor the test and you do that over and over again. Why did […]
Test Driven Development Get Started
The start is always the hard part. Most often we face existing code where we have to add some new functionality. In always all cases there are little to no unit tests, but ugly and complicated looking integration or system tests which sometimes fail because of timing, network, or database issues. If you have already […]
Test Driven Development is Pretty Cool
A couple of years ago I stumbled over one of the best articles about test-driven development I ever read. Even the title is crispy I mean Stepping Through the Looking Glass: Test-Driven Game Development how cool sounds that? Noel did a decent job to explain the mantra write a test, see it fail, write code, […]
ECS Pattern: Follow Entity
When I write games I have always something following something else. The camera follows a hero. Light follows ghost. Goody follows the space ship. Weapon follows the player. And so on and so on. This is a very common pattern in games. In the object-oriented world, I would probably have a reference to the object […]
