4 1. Introduction Our project is a mathematics-inspired game. Now in the game application market there are a lot of game related to mathematic but most of these are pure mathematic which will be a boring game, or a game which using only easy mathematic which is for middle school students or lower to play it. So it will not use much effort to solve these mathematic problems. But our group are going to make a game for high school students or higher to play with this game because high school level mathematic, player will have to solve some equations that player have to use some effort to solve it. Now our game has the mathematical problem in it, prepare for the users or players who play this game to solve it. But as we said before pure mathematic game is boring, so we are going to make it interesting by using puzzle game mix with this game. The kind of puzzle game that we will use is ROOM ESCAPE game. This game, player will have to solve the puzzle to get the item or hint to find the way out of the room, and we will use this kind of puzzle game mix with mathematical game, so player will not solve only the puzzle but player have to solve mathematic problems too. What make this game important is that, First the not much this puzzle-math game in the game application markets. Second the game can be used for review or practice the basic mathematical knowledge for high school level or higher. Finally we will implement this game into an android game application, because nowadays most of smart phone are using ios or Android, but most of people are using Android because it is easy to use and has more flexibility than ios. But later on we might implement on ios. 2. Background Mathematics is used in various kind of present technology, used for calculation, for solving a problem, for forecasting etc. And the aim of our project is high school math game, so what is taught in high school are: Sets Boolean algebra Exponential and logarithm Linear, Quadratic equation Polynomial Functions Series and Sequences Probability Basic Calculus Other (May or may not be covered depend on each schools) So in this game there will be these kind mathematical problems in this game. For the purpose of this game is for high school students or higher who does not School of ICT, SIIT Page 1

5 want to review their math using some thick text book, but by play this game they will have fun to play and solve math too. By playing this game player can review the basic mathematics that was taught in high school. 3. Objectives The aim of this project is that this game can be played by high school students and university students, and they are see it as interesting game and can use it for practicing basic math in high school level or basic university level. In order to achieve the project aim, the following objectives must be met: 1. Study more Java 2. Study more Android Application development 3. Learn what mathematics are teaching in high school or higher 4. Outputs and Expected Benefits 4.1 Outputs The output of this project is: 4.2 Benefits The android game. The report about the game. High school students, university students, and other people who want to practice mathematical knowledge and skills to solve it. We make it as an android application so other people can play it easily on smart phone. 5. Literature Review There are several ROOM ESCAPE games on the website, or even on mobile application. We want to review some of these games to help us understanding the basic of the game for developing the project. Crimson Room This game is about someone being locked in a room. You have to find the key item to get out of this room. You may have to combine some items for it to work properly. Or get the hint from outside the game. But some part of the game cannot be click properly so you will not know that you can move or operate that item or not. [4] School of ICT, SIIT Page 2

6 Figure 1: Crimson Room: one side of the room of the game Kazahana-No Exit This game is also someone being lock on this room. There is a simple calculation about the items in the game. But this game has a lot of confused clues to clear this game, so it is really hard to clear the game. [4] Figure 2: Kazahana-No Exit: one side of the room of the game Poco Escape This game is about the bear doll that wants to help the crying girl outside the door. There aren t many items in this game but the clues are clear and understandable. This game is much delayed maybe the frame rate is low, so we can see the unconnected picture. [4] School of ICT, SIIT Page 3

7 Figure 3: Poco Escape: one side of the room of the game Room Break This game is also someone is trapped in a somewhere not just room then use clues and items to find the way out. And this game also has a challenge of memory that you have to memorize something get it in order to get the items or clues. And the interesting of this game is that the story of each stage is connected and very fun to play. [5] Figure 4: Room Break: Preview of this game on App store School of ICT, SIIT Page 4

8 Dooor 3 room escape this game each room has different tricks, clues, or items but some of the items can be used in further rooms. Even no story behind the game but each room has very clear how to solve. This game has motion sensor that you have to interact with your smart phone to spin, to put the phone upside down, so that you can solve that room. [5] Figure 5: Dooors 3 - room escapes: 2 samples stages of the game Haunted room this game is also the game that you have to find the way out of this room. But what this game is different to the other is, if player solve wrong way or move into the wrong place the game will end. Let call this Bad END. But if you do in the correct order also the game will end. Let call this Good END. [5] Figure 6: Haunted room: 3 samples view of the game School of ICT, SIIT Page 5

9 6. Methodology 6.1 Approach First we have to think about how the game will be, set up the requirement and collect the math and puzzle problems. Second we have to study how to use eclipse to create a two dimensional game on android application. Third we have to design how the game could be play. In this project we mainly focus on high school students and higher, so we want to create it to be challenged game mode and the problem must not be too hard to solve. We will create challenge mode using time. First mode is we will have fixed number of rooms for solving then the timer will count, if player can clear that number of rooms without mistake the game will be clear and the time will be record how much time the player takes to solve but if player make a mistake on one of the room the game will be over. We will call this Time challenge mode. Figure 7: Flow chart of Time challenge mode Next we will create other mode call Endless mode. This mode player will have limited of time to solve each room. Once you pass, the player will have to solve another room endlessly until player time out or make a mistake on solving some room. School of ICT, SIIT Page 6

10 Figure 8: Flow chart of Endless mode In order to clear the rooms player have to solve the logic trick or puzzle to get the part of mathematic equation then solve that mathematics equation. After we finish designing the application, then we will design a user interface. After that, start implementing, Testing and reviewing the code. School of ICT, SIIT Page 7

11 6.2 Tools and Techniques Tools Eclipse is an IDE (integrated development environment) use for implementing Java project. Android ADT (Android Developer Tool) is a plugin for Eclipse use for developing Android applications Techniques - Java Programming skills - Android development skills - Game development skills - Adobe Photoshop.. School of ICT, SIIT Page 8

12 7. Technical Description 7.1 Description of the game In our application, there are two main modes which are endless mode and time challenge mode. Player will have to choose one of these two modes to play. In this game, each stage will have a unique problem, so we have to design each stage individually. During the play, the stages will be randomly selected. This game is aim for high school student or higher to make use of this game for reviewing their high school mathematics, but player has to solve the problems by the hint that is given in each stage player doesn t solve math problem directly). And for concentration player has only one chance to answer the question, so they have to answer carefully. 7.2 User interface design In this game, in the home page, player has two buttons for the mode selection and one help guide button as shown in Figure 9. Figure 9: Home page If player selects endless mode, player will go to play directly. But if the player selects time challenge mode, before go to play player has to select how many stages they want to play. There will be a choice of how many stages they can select. In Endless mode, you have to answer the problems endlessly until you answer wrong or the time is up. As you can see in (Figure 10), there will be a time counter which will count down until 0. A high score counter to keep a record. Stage clear counter is for showing how many stages player clear during the play. Player has to click the box next to the door to have an alert dialog for putting in the answer. School of ICT, SIIT Page 9

13 Figure 10: Example of Endless mode In Time challenge, after player selects how many stages they want to play. Player will have to solve the problem like in the endless mode, but instead of time limit, in this stage timer will count up until you solve all of the number of stages player has selected. There is a counter to check how many stages are left. Figure 11: Example of Time Challenge mode School of ICT, SIIT Page 10

14 7.3 Implementation Detail In this part, I will explain about the important code that use in this game Countdown Timer Figure 14: Countdown time Figure 15: Countdown time code This is a countdown timer use in the Endless mode. In the code new CountDownTimer(X,Y). X is the start time using the unit in milliseconds. And Y is how fast the counter countdown. In this case, it is countdown by every 1000 millisecond or every 1 second. When the time is up it will call method onfinish() which will call the gameover() method which will say that the game is over. *Note every 1000 milliseconds equal to 1 second. School of ICT, SIIT Page 11

15 7.3.2 Count up Timer Figure 16: Count up time Figure 17: Count up time code This is a count up timer which use in the Time Challenge mode. In this code I use runnable class which use the system time to count. So it will count up until reach the limit of an integer number. School of ICT, SIIT Page 12

16 7.3.3 Dialog for answering Figure 18: Dialog for answering Figure 19: Dialog for answering code This code is for creating an answering dialog for answering the question. There will be 2 buttons OK and Cancel. OK button is using for confirm the answer. And Cancel button is using for close the dialog. In this code it is also use for checking the correct answer after confirms the answer. If the answer is wrong it will call gameover() method and the game is over. But if the answer is correct it will randomly go to next stage. School of ICT, SIIT Page 13

17 7.3.3 Game over dialog Figure 20: Dialog for game over Figure 21: Dialog for game over code This code is the method that will be called after the time is over in Endless mode or when put in the wrong answer. It will make a dialog which will have only OK button. After click the OK button, it will go back to the home page. School of ICT, SIIT Page 14

18 7.4 Instruction How to play this game. As we explained in User interface design of how the game works. But there is more than just answering the problems. Player cannot answer the question directly. Player will have to find hint and use hint to find the answer. For example, Figure 10: Example of Endless mode In this figure 10, there are no ways to know the answer for x. So player have to find the hint we hide in this stage. If player clicks the bin, the hint will show up (figure 12). Figure 12: Hint inside the bin image School of ICT, SIIT Page 15

19 And if player clicks on the picture on the wall, the hint will also show up (figure 13). Figure 13: Hint behind the picture image And then player has to use this hint A equal 1 and Z equal 26 and know that each alphabet letters are the numbers from 1 to 26. So the alphabets player doesn t know are D and P. From the hint player will know that D and P are 4 and 16 respectively. Then factorize this problem and get the answer. School of ICT, SIIT Page 16

20 Another example, Figure 11: Example of Time Challenge mode In this stage (figure 11), the hint is on the wall and the polygon and the colour have the relationship green x, red y, and blue z of the question. The number of angles of the polygon is used to be number of x, y, and z. For example green triangle and green x has the same colour, so the number of angles of triangle is 3. Then x = 3. For y and z equal 4 and 5 respectively. And use trigonometry formula to find what is sinθ. School of ICT, SIIT Page 17
