我一直在試圖用一個相當簡單的（也許是錯誤的）方式製作一個生命遊戲程序。從技術上講，它似乎可行，但是當我試圖運行一些測試用例時，結果並不適合在線使用示例。Java中的生活程序遊戲
這裏的主類：
package gameOfLife;import java.applet.*;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.Rectangle;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import gameOfLife.Cell.State;
public class CreateGame extends Applet implements Runnable, MouseListener, KeyListener {
private enum GameState {
SETTING, START
}
private GameState state = GameState.SETTING;
private Image image;
private Graphics second;
private Cell[][] cells = new Cell[200][120];
private int indexI = 1;
private int indexJ = 1;
@Override
public void init() {
setSize(1000, 600);
setFocusable(true);
Frame frame = (Frame) this.getParent().getParent();
frame.setResizable(false);
frame.setTitle("Game of Life - Settings");
for (int i = 0; i < cells.length; i++) {
for (int j = 0; j < cells[0].length; j++) {
cells[i][j] = new Cell(i * 5, j * 5);
}
}
addMouseListener(this);
addKeyListener(this);
super.init();
}
@Override
public void start() {
Thread thread = new Thread(this);
thread.start();
super.start();
}
@Override
public void run() {
while (true) {
if (state == GameState.START) {
for(int i=1; i<cells.length-1; i++){
for(int j=1; j<cells[0].length-1; j++){
update(i, j);
}
}
}
repaint();
try {
Thread.sleep(125);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public void update(int i, int j) { //updating the cells into ALIVE/DEAD state
int[] neighbors = new int[8];
int sum = 0;
for (int index = 0; index < 8; index++)
neighbors[index] = 0;
if (cells[i - 1][j - 1].state == State.ALIVE)
neighbors[0] = 1;
if (cells[i][j - 1].state == State.ALIVE)
neighbors[1] = 1;
if (cells[i + 1][j - 1].state == State.ALIVE)
neighbors[2] = 1;
if (cells[i - 1][j].state == State.ALIVE)
neighbors[3] = 1;
if (cells[i + 1][j].state == State.ALIVE)
neighbors[4] = 1;
if (cells[i - 1][j + 1].state == State.ALIVE)
neighbors[5] = 1;
if (cells[i][j + 1].state == State.ALIVE)
neighbors[6] = 1;
if (cells[i + 1][j + 1].state == State.ALIVE)
neighbors[7] = 1;
for (int index = 0; index < 8; index++)
sum += neighbors[index];
if ((sum < 2 || sum > 3) && cells[i][j].state == State.ALIVE)
cells[i][j].state = State.DEAD;
else {
if (sum == 3 && cells[i][j].state == State.DEAD)
cells[i][j].state = State.ALIVE;
}
}
@Override
public void paint(Graphics g) {
Graphics2D g2d = (Graphics2D) g;
Rectangle r;
for (int i = 0; i < cells.length; i++) {
for (int j = 0; j < cells[0].length; j++) {
if (cells[i][j].state == State.ALIVE) {
r = cells[i][j].getCell();
g.fillRect((int) r.getX(), (int) r.getY(), (int) r.getWidth(), (int) r.getHeight());
}
}
}
super.paint(g);
}
@Override
public void update(Graphics g) {
if (image == null) {
image = createImage(this.getWidth(), this.getHeight());
second = image.getGraphics();
}
second.setColor(getBackground());
second.fillRect(0, 0, getWidth(), getHeight());
second.setColor(getForeground());
paint(second);
g.drawImage(image, 0, 0, this);
}
@Override
public void mousePressed(MouseEvent e) {
if (state == GameState.SETTING) {
int x = e.getX() - e.getX() % 5;
int y = e.getY() - e.getY() % 5;
cells[x/5][y/5].born();
}
}
@Override
public void mouseEntered(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseClicked(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseReleased(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_SPACE) {
if(state == GameState.START)
state = GameState.SETTING;
else
state = GameState.START;
}
}
@Override
public void keyReleased(KeyEvent arg0) {
// TODO Auto-generated method stub
}
@Override
public void keyTyped(KeyEvent arg0) {
// TODO Auto-generated method stub
}
}
我的方式製作的節目，通過按空格鍵你設置（通過點擊屏幕來創建細胞上改變了遊戲狀態，這暫停遊戲）和開始，使遊戲自行運行。 細胞是一類我創建了包含矩形和狀態：
package gameOfLife;
import java.awt.Rectangle;
public class Cell {
final int Measure = 5;
public static enum State{
DEAD, ALIVE
}
private Rectangle cell;
private int x, y;
public State state;
public void born(){
state = State.ALIVE;
}
public Cell(int x, int y){
state = State.DEAD;
cell = new Rectangle(x, y, Measure, Measure);
this.x = x;
this.y = y;
}
public Rectangle getCell(){
return this.cell;
}
}
如果任何人都可以進行測試，並告訴我有什麼錯這將是偉大的程序邏輯，因爲整體的工作，但是可能存在一些小問題，我不能把手指放在哪個螺絲上。
這可能是對http://codereview.stackexchange.com/ –
如果你犯了一個可重複的例子，與樣品輸入這可能是適當的位置更爲合適，預期輸出的描述，以及可能的錯誤輸出樣本。 「這裏是代碼，發現錯誤」不是人們通常在這裏迴應的。 –
對不起，我真的不知道這個地方是如何工作的。我想我可以像我一樣發佈它，如果有任何需要澄清或輸出的例子，我會在評論中發佈它。 – user3917631
