Introduction Very popular type of arcade action game

The player controls an object, for example a plane, spaceship, or car, which moves over a scrolling background.

Obstacles appear on the background that must be avoided and enemies appear that must be shot.

Often bonus objects appear that can be picked up for addition benefits.

During the game the number, variety, and strength of the enemies increases making it harder and harder to survive.

Agenda

The player flies in a plane over a sea and

enemy planes try to destroy the player.

How to create the illusion of motion using a

scrolling background

How to control the plane

How to make enemies and bullets

How to deal with the score, with lives and

with the damage of the plane.

The use of variables.

2011-09-09

Variables and properties x : the x-coordinate of the instance

y : the y-coordinate of the instance

hspeed : the horizontal speed (in pixels per step)

vspeed : the vertical speed (in pixels per step)

direction: the current direction of motion in degrees (0-360; 0 is horizontally to the right)

speed: the current speed in this direction

visible: whether the object is visible (1) or invisible (0)

solid: whether the object is solid (1) or not solid (0)

2011-09-09

For Example

Our spaceship to be able to shoot only once every five steps in the game

◦ can_shoot : the variable to see whether this is allowed

1 : shooting is allowed

0 : shooting is temporarily not allowed

◦ the creation event/ an alarm event

variables to indicate whether the spaceship has an active shield, whether it has some special weapon upgrade, etc.

2011-09-09

If a variable has a value To check what the value of

a particular variable is

◦ If the value of the variable is equal to the number given, the question returns true and the next action or block of actions is performed.

◦ If it is not equal, the next action or block of actions is not performed.

To indicate that the check should be whether the variable value is smaller than the given value or larger than the given value

2011-09-09

The player controls the big yellow plane that flies upwards.

All four types of enemy planes are shown in the image above.

At the bottom the score, number of lives left, and

the damage (in the form of the green bar) are shown.

1945 design document

Description

◦ Control a plane flying over a sea

◦ Encounter an increasing number of enemy planes

that try to destroy you.

◦ Avoid these or shoot them.

◦ The goal is to stay alive as long as you can and to

destroy as many enemy planes as you can.

2011-09-09

Game objects

◦ The background : A scrolling sea with some islands.

◦ The player’s plane: Flies over this sea.

◦ Bullets: Shot to destroy enemy planes.

◦ Four types of enemy planes:

A plane that you encounter and should be destroyed,

A plane that fires bullets downwards,

A plane that fires bullets towards the player’s plane,

and a fast enemy plane that comes from behind rather

than from the front.

2011-09-09

Sounds

◦ There are some explosion sounds and there is some background music.

Controls

◦ The player controls the game with the arrow keys.

◦ With the space key you fire a bullet.

◦ Only one bullet can be fired every five steps.

Game flow

◦ The player immediately jumps into the game.

◦ The player has three lives.

◦ When all lives are gone a high-score table is shown.

◦ Pressing the <F1> (help) key will give a brief explanation.

◦ Pressing the <Esc> key will end the game.

Levels

◦ There is just one level, but more and more enemy planes will arrive:

◦ first only the easy type but later the more difficult types.

The illusion of motion(동작의 환상)

In the game 1945 the game world scrolls

vertically.

The impression as if it flies over the scrolling

background

2011-09-09

How do we create a scrolling background

Two possibilities

1. To use a tiling background image that

moves downwards through the room

2. To build a much larger room but only show part

of the room using a so-called view

small image as a background resource

name : back_water

2011-09-09

Water.png

back_water

To change three settings

1. Uncheck the box labeled Draw background color

2. In the middle click on the menu icon and

select the back_water background image

3. To make the background move, set the Vert.

speed to 2.

To enhance the feeling of motion

[2] ENEMY AND WEAPON- 파일명: 1945_2.GMK

Enemy and Weapon

To extend our game with some enemy planes and a canon on the plane that you can fire

◦ a bullet sprite

◦ The bullet should be fired when the user presses the space key

◦ Allow the player to fire two bullets every second

a variable can_shoot : set this variable to 1/0

◦ If so we create a bullet just in front of the ship, relative at position (0,-16)

◦ Set alarm 0 to 15.

2011-09-09

Create a sprite

for the enemy plane and an object

◦ In the creation event we set the vertical speed to 4

to make the plane fly downwards.

◦ When the plane reaches the bottom of the room

we make it reappear at a random place at the top

of the room, in exactly the same way as we did for

the islands.

more of them over time.

◦ controller_enemy

To control the creation of enemy planes

make the object invisible during the game by unchecking

the box labeled Visible.

Creation Event

create an enemy place at a random location

just above the room.

2011-09-09

Tab: main1

Set the alarm clock to 200.

In the event for this alarm clock we create another

enemy plane and set the alarm clock again, but this time

to 500.

The effect is that at the beginning of the game there is

one enemy plane. After 200 steps, that is, about seven

seconds, a second enemy plane appears. After about 15

seconds, a third plane appears, etc.

[3]SCORE, LIVES, DAMAGE

Agenda

Make a new object called the controller_life.

◦ It does not need a sprite as we will control the

drawing itself using the drawing event.

◦ To show the score, the damage (in the black area

at the left), and the number of planes left, that is

the number of lives.

Check for the health and lives

◦ Make some changes in the collision event of the

enemy plane and the main plane.

[4] MORE ENEMIES- 파일명: 1945_4.GMK

Agenda

To add three new types of enemy planes to

our game.

◦ One will fire bullets straight down.

◦ The second plane will fire bullets towards the main

plane.

◦ The third type will not fire bullets but comes from

the bottom of the room and is more difficult to

avoid or shoot.

[5]FINISHING THE GAME -파일명: 1945_5.GMK

Agenda

To turn it into a real game a couple of finishing

touches

◦ Some background music, a loading image, a better

icon, etc.

◦ A delay in planes to reappear when shot, making it

more interesting for the player to try and shoot

planes, rather than simply avoid them.

◦ A special fire bonus

when the player reaches a score of 400

and another one when he reaches 1000 points.
