我目前正在制作《贪吃蛇》游戏。我有创建一个基本的二维数组列表的想法，这样我就可以创建单元格，但我找不到任何形式的帮助来创建该二维数组列表来存储每个单元格的 x 和 y 值。我需要有关如何创建二维数组列表以及如何使用它的帮助。
蛇.java
package snake;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.GridLayout;
import java.awt.List;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.ArrayList;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Snake extends JPanel implements KeyListener {
private static final long serialVersionUID = 1L;
static final int BOX_WIDTH = 600;
static final int BOX_HEIGHT = BOX_WIDTH;
int UPDATE_RATE = 300;
ArrayList<Cell> CellList = new ArrayList<Cell>();
//ode below????
//2d arrayList
ArrayList[][] Cell = new ArrayList[10][10];
public Snake() {
setPreferredSize(new Dimension(BOX_WIDTH, BOX_HEIGHT));
/*for (int i = 0; i < 5; i++) {
for (int j = 0; j < 5; j++) {
CellList.add(new Cell(i,j));
}
} */
Thread gameThread = new Thread() {
public void run() {
while(true){
repaint();
try {Thread.sleep(1000/UPDATE_RATE);}
catch (InterruptedException ex) {}
}
}
};
gameThread.start();
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
JFrame frame = new JFrame("SNEK");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Snake snake = new Snake();
frame.setContentPane(snake);
frame.setSize(BOX_WIDTH, BOX_HEIGHT);
frame.pack();
frame.addKeyListener(snake);
frame.setVisible(true);
}
});
}
public void paintComponent(Graphics g) {
g.setColor(Color.pink);
g.fillRect(0, 0, BOX_WIDTH, BOX_HEIGHT);
/*for (int i = 0; i < 5; i++) {
for (int j = 0; j < 5; j++) {
CellList.get(i,j).draw(g);
}
} */
}
@Override
public void keyPressed(KeyEvent arg0) {
}
@Override
public void keyReleased(KeyEvent arg0) {
}
@Override
public void keyTyped(KeyEvent arg0) {}
}
Cell.java
package snake;
import java.awt.Color;
import java.awt.Graphics;
public class Cell extends Snake{
private static final long serialVersionUID = 1L;
final int CELL_HEIGHT = 10;
final int CELL_WIDTH = 10;
int status = 0;
int xPos;
int yPos;
public Cell(int x, int y) {
xPos = x * 120;
yPos = y * 120;
}
public void draw(Graphics g) {
g.setColor(Color.magenta);
g.fillRect(xPos, yPos, CELL_WIDTH, CELL_HEIGHT);
}
}
最佳答案
如果你想用java制作游戏，我建议你使用游戏开发应用框架-libGDX
下载:https://libgdx.badlogicgames.com/download.html
它易于使用，而且您可以同时为桌面、Android、iOS 和 html 构建游戏。YouTube 上有很多关于 libGDX 的教程。
以下是其中一些:
