This article talks about an update on the interrupts used to hide sprites. I also detail the way I handle events to make levels in the game.

This time, I made a system to handle enemies and their bullets. I discovered some things about sprites that will change the way I’m making enemies. I also implemented some visual “tricks” with interrupts, and did a bit of optimization.

Starting with this post, I’ll try to keep a history of the development process of my Game Boy game. This week, as an enemy appear on-screen on the background layer, he’ll shoot a bullet.
