This article mainly introduces "how to realize the minesweeping game in J2ME". In the daily operation, I believe that many people have doubts about how to realize the minesweeping game in J2ME. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "how to realize the minesweeping game in J2ME". Next, please follow the editor to study!

Generally, according to the java development model, this kind of program is generally divided into three modules to develop.

There are three as follows:

A master file for the operation of a program, that is, an inheritance of midlet

The presentation class of an interface, that is, an inheritance of canvas, there should be some menus on the interface, such as new, exit, etc., then you should implements a commandListener message listening class (you can understand java message monitoring as a thread that keeps an eye on things pleasing to the eye as the Japanese invaders do. Of course, this refers to the messages he can reach, when he receives the message. An abstract function public void commandAction (Command c, Displayable d) is called, and this abstract function allows us to process the received message (message response) through its implementation.

The last one, of course, is the logic unit that has nothing to do with the interface, where we define the logic of the whole game to separate the logic from the interface. This is my biggest gain from learning java, hehe.

First of all, officially begin the first lecture.

My assumption is that the map of minesweeping is usually a rectangle, because the mobile phone with a round screen looks abnormal, and there is no need to accommodate it, so I can represent the whole map with a two-dimensional array of astatb.

After you have a map, some of the classes in the map naturally represent landmines. in this case, it would be better to do so.

/ * *

* 20 Mark the location as a landmine

The number of * = 10 indicates the number of opened squares and the number of mines around them.

* * /

The method of representation came out, and the logic became clear.

I'm going to open a piece, and all I have to do is add 10.

The first step in Java programming is, of course, to ask class first.

Package games

Import java.util.Random

Import java.lang.Math

Class gamelogic {

/ * * represents a 10-10 chessboard * /

Private int [] pan = new int

Private Random random;// is a random variable used to specify which locations are mines.

Private int BombNum = 0; / / Statistics of the total number of mines

/ * * whether the game is over * /

Private boolean GameOver

The next step is to initialize the map. the map must first throw a mine on it, otherwise how can it be called mine clearance? after throwing the mine, of course, we will traverse the map once (we are still very merciful, we have to tell the comrade who clears the mine, how many mines there are at so-and-so, for example: "there are mines on the Chinese side at 01, 01 and 12:00, rooster at 14 o'clock, easterly wind at 2 o'clock and so on").

/ * * initialize the array to generate a map * /

Public void InitArray () {

For (int I = 0; I

< 8; i++) { 　　for (int j = 0; j < 8; j++) { 　　pan[i][j] = 0; 　　} 　　} 　　RandomArray(); 　　CountBomb(); 　　BombNum = Bomb(); 　　} 　　/**统计地雷总数 　　* @return int 返回地雷总数 */ 　　private int Bomb() { 　　int count = 0; 　　for (int i = 0; i < 8; i++) { 　　for (int j = 0; j < 8; j++) { 　　if (pan[i][j] == 20) { 　　count += 1; 　　} 　　} 　　} 　　return count; 　　} 　　/**随机决定地雷的位置*/ 　　private void RandomArray() { 　　int i, j, k; 　　// 先扔15个左右的地雷吧,注意,这里不一定有15个哦,因为随机值可能重复,我不管啦 　　for (int r = 0; r < 15; r++) { 　　k = java.lang.Math.abs(random.nextInt()) % 64; //random.nextInt(100); 　　i = k / 8; 　　j = k % 8; 　　this.pan[i][j] = 20; //指定该位置为地雷 　　} 　　} 　　/**统计棋盘上的数据*/ 　　private void CountBomb() { 　　for (int i = 0; i < 8; i++) { 　　for (int j = 0; j < 8; j++) { 　　int count = 0; 　　//当需要检测的单元格本身无地雷的情况下,统计周围的地雷个数 　　if (pan[i][j] != 20) { 　　if ( (i - 1 >

= 0) & & (j-1 > = 0) {

If (pan [I-1] [j-1] = = 20) {

Count + = 1; / / check whether the upper left space is a landmine

}

}

If ((I-1 > = 0)) {

If (pan [I-1] [j] = = 20) {

Count + = 1; / / check whether the space above is a landmine

}

}

If ((I-1 > = 0) & & (j + 1 = 0)) {

If (pan [I] [j-1] = = 20) {

Count + = 1; / / check if the left side is a landmine

}

}

If ((I > = 0) & & (j + 1 = 0) & & (I + 1 = 0)) {/ / check whether the upper space is empty

If (pan [I-1] [j] = = 0) {

IsNull ((I-1) * 8 + j)

}

If (pan [I-1] [j]

< 9) { 　　pan[i - 1][j] += 10; 　　} 　　} 　　if ( (i - 1 >

= 0) & & (j + 1 = 0) {/ / check whether the left is empty

If (pan [I] [j-1] = = 0) {

IsNull (I * 8 + (j-1))

}

If (pan [I] [j-1])

< 9) { 　　pan[i][j - 1] += 10; 　　} 　　} 　　if ( (i >

= 0) & & (j + 1 = 0) & (I + 1)
