My Level Design For 2D Scroll Game By Arron Coakley

Work Flow Arron Coakley

My idea is a sci-fi space shooter 2D game side scroll side. The background of the game is in space

since I’m creating a sci-fi game. The player controls a space ship (Player 1) which shoots red lasers. I

created this my self using game maker. The aim of the game is to destroy enemy ships and see how

long you can survive and how high you can get the score counter. However it’s not that easy because

the enemy’s ships shoot lasers at you and if you don’t avoid them your ship will be destroyed and

you will have to start over again.

These images are taken from my 2D shooter game:

This background is set in space because my game is a sci -fi game. You can also see the spaceship

which you control, there is also a shield bar which is your health, when this is depleted you will be

destroyed and finally you can see a score counter below the shield bar. This represents how many

enemy ships you have destroyed.

Intro:

This image below is player 1. I just used the pen tool to create this ship, all you have to do is click and

a square will appear and that’s how I created this ship. This is what you control when you play the

game. I created this in game maker; this is also known as a sprite. This is a space ship because the

theme of this game is sci-fi and it is set in space so that’s why I created a space ship. This space ship

has a weapon and the weapon shoots red lasers which will destroyed enemy space ships if hit by

them.

This image below is enemy 1 and I just used the pen tool to create this ship in game maker. This is 1

out of 2 enemy ships which try to destroy you. They shoot lasers at you and if you get hit by them

your shield bar will go down and eventually you will be destroyed. This enemy has an animation; the

animation is a white light in the middle of the ship going around. This enemy ship has low health, if it

is shot by your lasers once it will be destroyed instantly.

This image below is enemy 2 and I just used the pen tool to create this ship in game maker. This is

the second enemy ship which will try to destroy you. It also shoots lasers like enemy 1 does;

however this ship does not spawn as much as enemy 1. This ship has a red glow effect around it and

also it is a triangle shape unlike enemy 1, this is because I didn’t want the same type of ships

everywhere.

Creating an Object:


6

Step 4

These images shows how to create an object and how to code an object. Each event

has code in it some have massive amounts and some have only a few lines. Step 4

shows a peace of coding. This coding is for the Jet which is player 1, this is what it

looks like when it is complete.


7

Enter = Shoot

W = UP

A = LEFT

S = DOWN

D = RIGHT

This shows the coding for the movement of player 1.

As you can see it shows you how to move (UP,

DOWN, LEFT, RIGHT, SHOOT)

This also shows the limits which mean how far

player 1 and the enemy can go; it makes sure

nothing goes off the screen.

This type of coding is a step event; this means what

happen step by step in the game.

Keyboard Controls & Movement:


8

This image shows all of the tabs I used to create

the game. I used sprites to create player 1, the

enemy’s etc... I also used sounds effects to make

the game feel and sound better. I used the

background tab to upload my background. I also

used the objects tab to give the sprites some

code and make them function. The final tab I

used was the room tab which was to create the

level its self.


9

Click to create room

This what a room looks like completed. This is where

I created my level background and if you wanted to

create one this is where you go to do that.

Creating a Level:

Limits:


10

This image shows the coding for limits. You code limits to make sure

nothing goes off the screen. In the code you use the X&Y axis to set the

boundaries.


11

To make the background look like it

is moving get the same image as

background 1 but this time click

“Remove Background”

Creating a scrolling background:


12

This image shows the coding for the particle system. The particle system is the particles in the game

like the size, gravity, life etc…

Particle System Effect:


13

This is the sprite for the laser which player 1 shoots.

This

shows

the

code

for the

movement and the sound effect for the laser.

Player Projectile & Sound:

Select your audio

file Once you have selected an audio

file click open to confirm it

This button is to

play the sound

Click this to select

the audio file for

your sound.

Once you are finished

with selecting your

audio file click ok to

confirm it.


15

This is the code for spawning in the enemy’s objects, this shows the rate enemy which

spawn in the game.

Enemy Spawn & Movement:


16

This image shows the enemy shot by laser coding. This means when you shoot the enemy with your

lasers they will be destroyed and your score counter will go up.

Enemy destroyed:


17

Enemy laser sprite

This image is the enemy laser sprite.

This shows the code of the enemy projectile (enemy laser). This code makes the enemy laser

travel towards player 1 space ship. It also shows the code for the sound effect.

Enemy Projectile:


18

This image shows the enemy projectile in action. As you can see they are going towards player 1.

This shows the code for the shield bar. The coding tells you that the max percent it can reach is 100

and once it hits zero it will be gona and you will be destroyed.

This coding shows what colour I have

picked for the shield bar and where the

shield bar will appear on the screen. You

can have whatever colour and have the

shield bar where ever on the screen.

Shield Variable:


20

Shield Bar at 100%

Shield Bar at 50%

Shield Bar at 0%


21

This image shows the sprites

for the explosion for when

the player gets destroyed.

These sprites are an animation.


22

This shows the code for when the enemy laser hits player and what happens. When the player gets

hit the shield bar will go down by 25% each hit.

This shows the code for the score variable/counter.

Player being destroyed

This is the code for the score

counter, in this code it shows

what colour, font and where

the counter will appear.

Overall I’m happy with the 2D game I created. There were some problems but not too many like

misspelling in the code. However I finally solved the problems and I was able to continue making my

game. It was hard at first but eventually it became easier because I knew what to do and how to do

it. I have tested the final game and it works like I was hoping it would from the beginning. I enjoyed

working on the 2D side shooter game and I learned a lot from doing this.
