Side scrolling in GameMaker can be implemented with little effort. In this episode we take a step back from 2014 and take a look at how a 2d side scrolling games were implemented 20 years ago. Due to limited hardware, developers had to use smart memory management techniques to create the games that they wanted. In the 80s the best games were being made for consoles like the NES since they could support memory on the game card. In the early 1980s the standard graphics card for PCs; the CGA was not capable of even creating a satisfying 2d side scrolling effect. The Color/Graphics Adapter was IBM's first graphics card with a max resolution of 640×200, and support for 16 colors, and 16 kilobytes of video memory.

For a more more details on the CGA read on here.

This card did not have the capabilities to create the smooth side scrolling effect that NES and

o_pause

In today's episode we are going to create a pause effect that can be easily implemented into any game you may be working on. For this example we are going to build off of a minimalistic side scroller with only a few active objects.

Source code hosted on Github (pull, fork, or whatever you would like).

To implement the effect we will have o_player (this would be any control object in your game), trigger an event that creates o_pause which will handle all the logic for the effect.

o_player is the easiest part to implement so we should just take care of it first.

Room Creation Code

background_hspeed = -1;
instance_create(0,0,obj_city);

Parallax Backgrounds

In any side scroller you are going to see the Parallax Scrolling effect. This effect was (in my mind) huge for castle crawl games like Castlevania that would utilize it on any window or open scenery to immerse the player in a subtle way. The first appearances of Parallax scrolling can be traced to 1982 in a game called Moon Patrol (video link) and has been used in many games since.

For the purposes of this episode we are going to create a simple sprite based Parallax Scrolling effect.

We will use these 2 backgrounds: Background 1 & Background 2 to create the following basic effect:

MOVE_SPEED = 4;
WALK_SPEED = 10;

if(keyboard_check(vk_up)){
 y -= MOVE_SPEED;

##Basics of Working with Sprites In order to get the most out of Sprites we will undoubtedly want to add some animation and control to bring our objects to life.

In this episode we will take a look at the core of sprite control within Objects. We will also take a look at working with sprite sheets and using the built in Sprite Editor tool.

We will start with a single sprite spr_player that we control from a top down perspective through our obj_payer. Even though the player is moving around in the room we want to sync up some animation with the players input.

In order to do this we need to add the appropriate sprites for each of the movements that we will be using in our object. Luckily artists have given us the sprite sheet which is a clever way to shove all the relevant sprites we need onto 1 image.

For this project we will be using the artwork for the Liberated Pixel Cup and because we want

In order to understand each component it is important to learn as much about each of them as you can. The ultimate source for knowledge in GameMaker is of course the docs.
