A Journey in Game Dev


Month: September 2018

Here goes my first game!

Today I uploaded the first public demo of Goodie Assembly on!

Goodie Assembly is a relaxing casual puzzle game. Slices appear and move toward the center from 8 different directions. As a player, you try to get 8 slices to meet at the center in order to assemble a delicious goodie (tasty food) and make sure that the slices don’t stack up too many times or the game will be over.

The target platforms are actually App Store and Google Play Store but I hope a web version will help me get players’ feedback earlier.

How I learned to use State Design Pattern in my game

I learned finite state machine (FSM) in model of computation class at a university. I’ve loved it ever since. It turns out to be one of the most commonly used patterns in game development. State design pattern is not only easy to understand and implement but also very flexible. I think every game programmer should know about it, and ideally how to employ it.

I believe the best way to learn programming patterns is to apply them. In a recent game project, I learn faster by doing than reading or watching even though I enjoy good reads and tutorials from time to time. In a recent project, I had a chance to look closely at and evaluate (many of) the design choices that make FSM either very efficient or extremely painful to debug and maintain.
