Know what makes any game better? Parallax scrolling! I know that might sound like an overstatement, because it is. But parallax scrolling is really cool, so let’s add a small parallax effect to our game!

We have obstacles and the player can jump over them, but it doesn’t really matter…you don’t get rewarded when you do and you don’t get punished when you don’t. So let’s add a scoring system and collision to the obstacles so that there’s actual motivation to do things! Collision First we’ll take care of the collision detection. Go down into your main game loop and add the following if-statement after the code that moves the obstacle across the screen:

Now that we have obstacles, we need to enable the player to jump over them. However, in order to do that we need to use math. Don’t panic, SGDK makes it quite simple. Let’s go! Fixed Point Math To make the player jump we’ll have to change his vertical velocity to move him upwards, then apply gravity to pull him back down so that we get a jumping arc. We could do this using variables of type int, but this would lead to very hectic and jerky movement, because there’s just not much precision.

Alright, we got the background moving, now we need a player sprite to complete the illusion. Of course we could create very long levels and have the player actually run through them, but it is way more efficient to fake endless running by just scrolling the background past the player.

Welcome back! Last time we drew a background with a floor and even some street lights. This time we’ll get things moving by scrolling the background to create the illusion of endless running! Preparations As usual, we have to do a bit of preparation work. First off we’ll define a new constant at the top of the file that will store the speed at which our background will scroll. const int scrollspeed = 2; Next up we’ll set our desired scrolling mode.

Welcome back! Now that we have a framework, we can start building the game proper. Let’s start by importing some graphics and displaying tiles on the screen, so that our game stops looking like a text adventure. We’ll be using some graphics from the Game Creator’s Pack by Jonathan. You won’t have to download it, I’ll provide all the files you’ll need here, especially since I’ve edited some of them.

Welcome to a new tutorial series on Mega Drive development! Here we’ll be creating a Mega Drive game from scratch using SGDK, the Sega Genesis Development Kit. And this is what we’ll be working on: I call it Megarunner. It’s an endless runner-type game where you jump over obstacles to gain points. The game ends when you hit one of the obstacles. It’s a simple concept and thus a good way to learn about some new concepts of Mega Drive programming like scrolling and animation!
