List of sounds needed

Opening level intro Open close mouth Sound of ghost moving

Sound of ghosts faster Sound of ghosts super fast

Ghost scared Ghost scared beginning

Pac-Man eating ghost Pac-Man eating fruit Intermission sounds Game over Pac-Man dieing

Opening level intro

Length: 5 seconds Sound and feel: Should be up beat and

happy, use mid octaves If game begins/continue is used/quarter

is used/ and player enters game/enters game again Then sound plays one time (repeat if

previous if statement is satisfied)

Open/close mouth “eating”

Length: .5 seconds Sound and feel: should sound like Pac-

Man is eating pellets. Happy sounding, as if he is saying, oh yum!

Sound should be able to loop If Pac-Man enters space with a pellet

Begin playing sound until he leaves tile Continue sound/loop if there is a pellet in the

following tile

Sound of ghost/s moving

Length: .5 seconds Sound and feel: should sound like a

rotating happy sphere. If ghost begins moving

Then play sound and loop until fast sound of ghost/s moving begins

Sound of ghost/s moving faster

Length: .4 seconds Sound and feel: higher pitched version of

the sound of ghost/s moving If ghost is moving and has satisfied

requirements for the first stage of faster movement, Then play sound and loop until super fast

sound of ghost/s moving begins

Sound of ghost moving super fast

Length: .3 seconds Sound and feel: higher pitched version of

the sound of “ghost/s moving faster” If ghost is moving and has satisfied

requirements for the first stage of faster movement, Then play sound and loop until super fast

sound of ghost/s moving begins

Start of ghost running away sound

Length: 1 second Sound and feel: This should give a

feeling of tension, but also instill excitement in the player.

If player eats big pellet Then ghosts begin “Ghost running away”

sound file plays one time, Then “Looped: Ghost running away” plays in

a loop.

Looped: Ghost running away

Length: .3 Sound and feel: should sound fast, excited, and

high pitched. This should give a feeling of tension to the player, as if time is running out.

If player eats big pellet Then ghosts begin “Ghost running away” sound file

plays one time, Then “Looped: Ghost running away” plays in a

loop.

Pac-Man eating ghost

Length: .5 Sound and feel: Almost as if Pac-Man

just went *Chomp* If Pac-Man enters a square with a ghost

when the ghost is “Frightened” Then play sound file one time.

Play for each time Pac-Man enters a square with a “Frightened” ghost.

Pac-Man eating pellet

Length: .2 Sound and feel: high pitched, quick,

simple, one tone If Pac-Man enters a tile with a pellet

Then play sound one time Repeat for consecutive pellets as much as

needed.

Pac-Man eating fruit

Length: .5 Sound and feel: should be more exciting

sounding than eating a pellet, one tone pitch, quick, simple.

If Pac-Man enters a tile with a “Fruit” Then play sound one time.

Intermission music

Length: 10 seconds Sound and feel: should sound excited,

fun, entertaining. Think sort of like Ben and Jerry.

If Intermission begins Then Play sound file one time in sync with

movie.

Table of contents

Part 1: Co-operative game type – The Ghost Operative

Part 2: Competitive game type – The Fifth Ghost

How to start game for player 1 and 2

Player 1 or player 2 inserts coin and/or hits “Start”

Game starts Player 1 or Player 2 (Assume the prior

is not available), Said player inserts coin and/or hits “Start”

Game begins as Multiplayer Assume for each multiplayer mode, this

slide

Assumptions

Assume that there are two joysticks available on console, one for Player 1 and one for Player 2

Co-Operative

The Ghost Operative

What is it?

Player 1 and 2 swap roles as the “Ghost Operative”

What is the Ghost Operative? The Ghost Operative is a Pac-Man player

that is disguised as a ghost. He/she moves slower and still collects

pellets

How it works

At the start of a match, a random number is generated between 1-2 If 1 is chosen,

Then player one becomes Ghost Operative If 2 is chosen,

Then player 2 becomes Ghost Operative

Ghost Operative mode lasts 15 seconds.

Duration Duration of Ghost Operative = 15 seconds At start, player flashes one time and

changes into a “Grey” ghost form. When 3 seconds are left, player begins to flash

and 15 seconds is up, player becomes a Pac-

Man. Pac-Man becomes Ghost Operative

If Ghost Operative becomes Pac-Man (Alternate Player)

New Model/static image: Grey Ghost Note: other than the Dark Blue ghost the other ghosts (Ping Ghost ,

Orange Ghost Blue ghost , Red Ghost) are made the same way. Size – 16 x 8 pixels

Size is for all ghosts listed below Look and feel – should look “discreet” and “deceptive”. Use Basic ghost 1-3 Hex codes

Grey Ghost – 5a5a5a Use basic ghost as guide

Color in the 3 versions with hex codes listed above Take those 3 versions and save as separate files

Then make 4 different versions of each piece for animation by adding the eyes 0°, 90°, 180 °, and 270° Then save as separate files 4 separate files for

each of the 3 separate animations

Mechanics Ghost Operative collects pellets as normal

Pellets collected by Ghost Operative count towards level completion

Big Pellet If a Big Pellet is eaten, either by Pac-Man or Ghost

Operative Ghost Operative cannot eat ghosts.

Ghost AI will not actively target or run away from the Ghost Operative

The Ghost Operative can still die by touching a ghost. The Player moves at Normal speed as Pac-Man The player moves at 1/3 normal speed (Round up)

Pac-Man = 11 tiles per/second Ghost Operative = 4 tiles per/second

Part 2: Competitive Game Type

The fifth ghost

What is the “Fifth Ghost”? In the game of Pac-Man there are 4 ghosts,

Red Pink Light Blue And Orange

In the “Fifth Ghost” the player plays as a fifth ghost, but unlike his other ghost counter parts, he has full control of his/her character and can “Kill” Pac-Man in the same way that the other ghosts can.

Movement The ghost player’s ghost works off of the

same movement speed of the red ghost, speeding up as more pellets are eaten.

Controls Controls are simple and binary, should work as on/off

and operate one at a time. Once a direction has been chosen, Ghost Player will

continue forward without movement on the joystick For purposes of description, consider the top side of

the screen to be 90° and the left side to be 0°. Joystick pushed to 0° (-X axis)- Ghost Player turns

left/ moves in the 0° axis, Joystick pushed to 90° (+Y Axis) - Ghost Player moves

up, 90° axis, Joystick pushed to 180 ° (+X Axis) - Ghost Player

moves left, 180° axis, Joystick pushed to 270° (-Y Axis)- Pac-Man moves

down, 270° axis,

Lives How to get lives for player 1 or 2

Start game Player starts with 5 lives

Insert quarter/use continue Player gets 5 lives

If player runs out of lives Player gets “Counting screen” Counts down

from 9-0 At 0 player gets “Game Over”

Game ends Use base numbers for counting at center of

screen

The large Pellet The ghost player is susceptible to the effects of the large pellet If large pellet is eaten

Then the ghost player becomes “Frightened” during fright time, but does not lose control of his/her character. During this time the ghost player can be eaten by the

player playing as Pac-Man and the Pac-Man player gains points as he/she would the other ghosts.

If ghost player is eaten If ghost player loses 1 life. Then ghost player acts as a another ghost in the table

below, filling any of the slots, as do the other ghosts. 1st ghost = 200 2nd ghost = 400 3rd ghost = 800 4th ghost = 1600 5th ghost = 3200

Large Pellet length Ghosts enter frightened mode for X amount of seconds dependent

on level Unlike other modes, this mode has an arbitrary let amount for

seconds that “frightened” mode lasts after level 13. level 1 = 6 seconds level 2 = 5 seconds level 3 = 4 seconds level 4 = 3 seconds level 2 = 5 seconds level 6 = 5 seconds level 7 = 2 seconds level 8 = 2 seconds level 9 = 1 seconds level 10 = 5 seconds level 11 = 2 seconds level 1 = 12 seconds level 13+ = 2 seconds

Scoring

The second player gains 1000 points for every kill he/she gets. Not the other ghosts. These points count towards extra lives

Scoring is done the same way as the normal game with one exception There is a second score added up for the

second player.

Swapping roles

Once all pellets have been eaten in one round, Then a new round starts The new round has the last player who

played as Pac-Man, Play as the Fifth Ghost.

Advancing levels

After both players have been both Pac-Man and the Ghost Advance up 1 level

EX: player 1 plays as ghost, then as pac-man – player 2 plays as Pac-Man, then Ghost Level advances from 1 to 2

If neither player loses all of their lives, the level advances.
