1. Overview

Dragonball Z – The Sky Battle is based on the series in the famous Japanese comics Dragonball. In the story, Son Goku is a super fighter who has the ability similar to Superman’s. He fights against many evil invaders and saves the Earth again and again. He has many friends, and in particular, Vegeta is his friend as well as rival who always wishes to beat him. In , the ultimate evil fighter called Majin Buu is resurrected and brings a great threat to the Earth! Even in full power, Goku cannot beat him because Buu is fissionable. In order to gain more power, Goku now fuse with Vegeta to transform to the super fighter – Vegetto! Vegetto must kill as many Buus as he can to rescue our world, or else it would be disasterous.

For game play, Dragonball Z – The Sky Battle is just like the classic arcade top-down shooter 1942 with a different setting. In Sky Battle, the user plays as Vegetto and controls Vegetto’s position on the screen via the left, right, up and down arrow keys. Vegetto’s energy ball attack is released by the hitting of space bar. The goal of this game is to shoot down as many Majin Buu as possible in order to get more than 49999 points. During the game, more than one Majin Buu will appear on the screen (because he is fissionable), they will descend from the top to the bottom of the screen with a random track of motion. User will have 3 lives for Vegetto as default. When Majin Buu hits Vegetto with his body, Vegetto will lose 1 live by that. If all 3 lives are gone, then the game is over. On the other hand, user must manage to control Vegetto well and tries to avoid colliding with Majin Buus. User can kill Majin Buu by shooting energy ball to them. Majin Buu is killed if it gets shot, and user’s score is raised for each Majin Buu shot. When user’s score reaches a certain value, the amount of Majin Buu generated at a time will be increased and different forms of Buu will show up in order to level up the difficulty. If game is over, user can choose to re-play the game.

2. Game Mechanics

2.1. Overview

Dragonball Z – The Sky Battle is a 2D top-down shooter in the tradition of 1942. It has a background with a sky with clouds continuously scrolling so that the user can feels the speed. However, The Sky Battle only has one stage, one background with different levels of enemies. The game mechanics are designed in such a way as to allow the user extensive control of his super hero while the user can enjoy blasting off the enemies using different forms of attacks that are seen on the famous comics.

2.2. Camera Position

The camera position in this game is fixed to a “top-down” view without any swinging or zooming. The player can always see his/her character of the same size, moving freely at his/her own wish within the screen. Enemies are showing up from the top, descending to the bottom of the screen, all are with the same fixed default sizes.

User Interface Design

Before entering the game, there is a menu with two options appeared as two buttons, namely START and INSTRUCTIONS.

START: brings the player to a new game.
INSTRUCTIONS: brings out the instructions menu for this game.

In the game, the player’s screen shows a background of sky with scrolling clouds. Player’s character, Vegetto, is positioned at center by default. Of course, the player can move Vegetto around using arrow keys. In addition, player can find out two elements on the screen, telling the information about Vegetto’s status as follow:

Lives remained: they are at the right upper corner of the screen, each live is represented by the head of Vegetto. Player can only have at most 3 lives. Every time when Vegetto gets hit by Majin Buu, one live is taken away and one associated icon (the head) will disappear, denoting the loss of one live.
Score: it locates at the left lower corner of the screen, showing the current score that the player has. In order to beat the game, player must challenge to get higher than 49999.

The following is a sample screenshot:

Replaying and Saving

As this is a short and strict forward game, so once player has lost all the 3 lives, then game is over and player will be asked to click on “Continue”. If he does, the game just simply resets everything to the beginning: resets score to zero; resets lives to 3; reset level to the first one. There are not any checkpoints in this game. Therefore, in other words, player must pay attention or else he/she must start all over again.

Control Summary

The player will use the keyboard to maneuver Vegetto’s movement and attacks throughout the whole game. The controls are summarized below:

Up, Down, Left, Right arrow keys: The player will use this control to move Vegetto freely around the space within the screen. For instance, when player presses the right arrow key, Vegetto will fly to his right. The movement is crucial in this game because player must try to get more green Senzu beans while trying to evade any Majin Buu if he/she cannot kill it before it approaches.
Space bar: The player can press the space bar to shoot a small energy ball for attack. One small energy ball is good enough to kill a Majin Buu. In this attack, there can only be at most 5 energy balls appeared in the screen at one time.
“a” key: The player can press the character “a” key to trigger the shield attack. It will completely protects Vegetto from being hit by Majin Buu while killing the enemies. However, this weapon is too powerful and so there is penalty in using it: for each shield shot, 250 points will be deducted from the current score. Also, in order to trigger it, the player must at least have 2000 points in his/her current score.
The secret “z” key”: This weapon is supposed to be the bonus of this game. It is not as powerful as the “a” key, but it is much more powerful than the tiny space bar attacks. The good point is, it does not have any penalties! It is a thick laser which allows you to blast enemies with ease. However, the player is only acknowledged about the existence of this secret big bang attack after he/she beats the game once.

Game Play Details

The main idea is to freely move Vegetto over the space provided using the arrow keys on keyboard and to attack Majin Buu with energy ball by pressing the space bar, “z” key or “a” key. The details of the major game elements are discussed below:

Goal of the game: The goal is to shoot and kill as many Majin Buu appeared in the game as possible before Vegetto runs out of lives. The target score in order to beat the game is 50000. Different forms of Majin Buu have different score points, varying from 100 points to 300 points.
Character “Vegetto”: This is the character controlled by the player. Player must try to master the skills for Vegetto’s movement. There are 3 attack modes for Vegetto. The basic one is the small energy ball triggered by space bar. The second one is the big bang attack (a thick laser) triggered by “z” key. The ultimate third weapon is the huge energy shield triggered by “a” key, but this attack has its own penalty of –250 points in the score for every shot. Also, the big bang attack is only informed to players after they beat the game.
Character “Majin Buu”: These are the characters that are controlled by the computer. Player should try to kill all of them. There are 5 different forms of Majin Buu, that are with different sizes, different speeds of movement and different score points reward.
Senzu beans: These are the green beans that appear during the game occasionally. Each bean is worth 200 points and can restore 1 live of Vegetto.
Tips to win: player should, of course, kill all the Majin Buu that show up during the game. However, player can sometimes trigger the huge shield attack if there are too many Majin Buu to handle, yet, it cannot be used all the time, otherwise the score would always be too low due to the penalty of the shield. Another tip is to try to pick up all the beans, there are no reasons to reject them!

2.7. Cut-Scenes

There are no major cut-scenes in the game that would be beneficial to the game.

Storytelling

Solely based on the gameplay, there is actually not much for the story of this game. The story is just like the classics: hero beats the bad guy to save the world. However, using the animation features of FLASH, the opening of this game briefly talks about the story of this Dragonball shooting game, introducing the main characters: Vegetto and Majin Buu.

Level Summary

The level discussed here is talking about the different forms of Majin Buu that appears in the game according to the current score. The details are listed here:

1^st form: it will appear throughout the game. Its movement speed will increase as long as the score increases. Although its size is the smallest among the 5 forms, it has the fastest speed, ranging from +10 to +40, depending on the score. It is worth 100 points for reward.
2^nd form: it will also appear throughout the game. Its movement speed is fixed to +15. Its size is similar to the 1^st form, but it is worth 150 points for reward.
3^rd form: it will only appear if the score is between 5000 and 10000. Its movement speed is fixed to +15. Its size is bigger than the 1^st and the 2^nd forms. It is worth 200 points for reward.
4^th form: it will only appear if the score is between 10000 and 15000. Its movement speed is fixed to +15. Its size is bigger than the previous forms. It is worth 250 points for reward.
5^th form: it will only appear if the score is greater than 15000. Its movement speed is fixed to +15. Its size is the biggest. It is worth 300 points for reward.

3. Artificial Intelligence

Opponent AI

The enemies that Vegetto faces are the 5 different forms of Majin Buu. They have different sizes, different speed of movement and different score points for reward. However, their movement does not involve any AI due to the limited time of development of this game.

Player Detection

All forms of Majin Buu do not have the ability to detect and track the player.

Motion

Different forms of Majin Buu will have different descending speed (y-axis) of motion. However, they do not move strictly along the vertical y-axis. They also have x-axis motion. At random, Buu will either move straight, move to the right by 10 pixels or to the left by 10 pixels while they are descending to the bottom. Their probabilities are 3/5, 1/5 and 1/5 respectively.

Path Finding

There is no path finding ability for Majin Buu at all forms.

Special Actions

No special actions are designed in this game.

Combat

Although there are five different forms of Majin Buu, there is only one attack mode for them. They can only attack Vegetto by hitting themselves with him. Once the game detects the hitting, Vegetto will lose one live by that.

Non-player Characters

Besides the different forms of Majin Buu, there are no other NPCs appeared in the game.

Puzzles and Traps

Since this is only a plain shooting game, so unlike other adventure games, there are no puzzles and traps for this game. The main focus is to let player enjoy the shooting and destroying enemies, not solving puzzles or traps.

4. Game Elements

4.1. Items

The only item in this game is the green Senzu bean. It is worth 200 points for reward and it can restore 1 live for Vegetto. Here is the picture of it:

Character Bibles

Vegetto: this is the character controlled by the player. In the comics Dragonball Z, he is the super hero who can fly like Superman. User uses the left, right, up and down arrow keys to control Vegetto’s movement. When the correct key is pressed, Vegetto will have 3 attack modes to release energy ball from his hand to attack Majin Buu. Here is the picture of him:

Small energy ball: triggered by space bar
Big bang attack: triggered by “z” key
Huge shield attack: triggered by “a” key; with a penalty of –250 points in score for each shot

Majin Buu: this is the character controlled by the computer. In the comics Dragonball Z, he is the ultimate evil creature that is fissionable. In the game, there are more than one Majin Buu flying around the screen at one time. They attack Vegetto by colliding themselves with him. In total, there are five different forms appearing in the game. They are shown below:

1^st form: smallest size, fastest, worth 100 points
2^nd form: similar size with 1^st form, fixed speed, worth 150 points
3^rd form: bigger size, fixed speed, worth 200 points
4^th form: second largest size, fixed speed, worth 250 points
5^th form: biggest size, fixed speed, worth 300 points

5. Story Overview

Storyboard

In Dragonball Z, Son Goku is a super fighter who has the ability similar to Superman’s. He fights against many evil invaders and saves the Earth again and again. He has many buddies, and in particular, Vegeta is his friend as well as rival who always wishes to beat him. Goku and Vegeta are becoming stronger and stronger after each fierce battle with those evil fighters from other planets. In , the ultimate evil fighter called Majin Buu is resurrected and brings a great threat to the Earth! All fighters on Earth are defeated and died except the two greatest warriors: Goku & Vegeta. However, even in their full power, Goku and Vegeta cannot beat him because Buu is fissionable. Majin Buu keeps re-generating himself even his body is destroyed. In order to gain more power, Supreme Kai (the God) gives a pair of earrings to Goku. With each of them wearing one earring, Goku now fuses with Vegeta to transform to the ultimate super hero – Vegetto! The only way to stop the disaster is to kill ALL Majin Buus at a time!
5.2. Plot Summary

Simulated the story in in Dragonball Z, Vegetto will battle with Majin Buu in the sky while Majin Buu is fissionable. Vegetto needs to use his greatest power to destroy all the Majin Buu in the sky, all at the same time.

In the upper right corner of the screen, user can see the number of lives of Vegetto remained. In the left bottom corner, user can see the scoreboard that shows user’s current score. For the characters, user is controlling Vegetto with golden hair, who is positioned in the middle of the bottom screen at start while Majin Buu is the fat and pink monster floating in the sky. If Majin Buu is shot, it will disappear and fade away. On the other hand, Vegetto is acting the same when he collides with one of the Majin Buus. When user loses all the 3 lives of Vegetto, a button will appear on the screen to ask user to try again.

6. Game Progression

Setting

The Sky Battle takes place on the Earth in the imaginary world created by Akira Toriyama in Dragonball Z. It is a world very similar to the real one. However, there are more super fighters that have the ability like Superman’s. The story starts by saying that the ultimate evil creature Majin Buu is revived from death. He is assumed to be purely evil and most powerful in the universe. Even uniting the power of all the fighters on Earth, Majin Buu is still invincible. Now the hope falls onto the two super fighters called Goku and Vegeta. Through fusion, they combined into one body and the greatest warrior Vegetto is born. He must stop Majin Buu from destroying the lives on Earth as soon as possible because the demolition is giant already and disaster is everywhere.

Introduction

The player controls the super fighter Vegetto. By using different attacks, the battle between Vegetto and the large number of evil creatures is going to be huge!

Flowchart for Majin Buu

1^st and 2^nd forms of Majin Buu show up at start by default

Score is between

5000 to 10000

1^st, 2^nd and 3^rd forms of Majin Buu show up in the game

Score is between

10000 to 15000
1^st, 2^nd and 4^th forms of Majin Buu show up in the game

Score is more than

15000

15000
1^st, 2^nd and 5^th forms of Majin Buu show up in the game

Level and Scene Details

Levels are referring to the different forms of Majin Buu appeared in the game. The criteria for each form of Majin Buu are shown in the flow chart in 6.3 above.
For Scene, there is only one scene, the sky with scrolling clouds, throughout the game due to the short period of development time. The scrolling clouds give player a feeling of fast flying speed of Vegetto.
