我正在尝试创建俄罗斯方块 GUI。我的朋友写了后端。到目前为止,我们只是将俄罗斯方块板(或我在代码中提到的网格)打印到控制台窗口。在下面的代码中,我设置了一个 JTable 作为俄罗斯方块游戏的棋盘。我想知道如何让我的 JTable 根据从 Window 类顶部声明的俄罗斯方块“游戏”传递的网格来渲染每个网格元素。这个网格是一个整数值的二维数组,它引用 Pieces 类中枚举的颜色。有什么建议么?到目前为止,它只打印一种颜色。
我还发布了一些俄罗斯方块类的代码,以便您可以看到那里可用的方法和参数。
这是我的代码(希望在 SSCCE =p 中):
public class Window {
JPanel cards;
final static String SPLASHSCREEN = "SplashScreen";
final static String MAINMENU = "MainMenu";
final static String TETRIS = "Tetris";
final static int GRID_ROW_HEIGHT = 30;
final static int NUM_ROWS = 20;
final static int NUM_COLS = 10;
JTable table = new JTable(new MyTableModel());
Tetris game = new Tetris();
public void addComponentToWindow(Container pane) {
// Create the "cards"
.
.
.
// SplashScreen setup
.
.
.
// MainMenu setup
.
.
.
// Tetris setup
final JButton startGame = new JButton("START GAME");
card3.setLayout(new GridBagLayout());
GridBagConstraints gbc2 = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 0;
gbc.insets = new Insets(2, 2, 2, 2);
card3.add(startGame, gbc2);
gbc.gridy = 1;
startGame.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
table.setDefaultRenderer(Object.class, new MyRenderer());
table.setRowHeight(GRID_ROW_HEIGHT);
table.setFocusable(false);
table.setRowSelectionAllowed(false);
for (int i = 0; i < game.getNumCols(); i++) {
table.getColumnModel().getColumn(i).setPreferredWidth(table.getRowHeight());
}
card3.add(table);
card3.remove(0); //Removes button
card3.revalidate(); //Redraws graphics
}
});
// Sets up layout
cards = new JPanel(new CardLayout());
cards.add(card1, SPLASHSCREEN);
cards.add(card2, MAINMENU);
cards.add(card3, TETRIS);
// Creates the actual window
pane.add(cards, BorderLayout.CENTER);
}
public Color getTableCellBackground(JTable table, int row, int col) {
TableCellRenderer renderer = table.getCellRenderer(row, col);
Component component = table.prepareRenderer(renderer, row, col);
return component.getBackground();
}
class MyRenderer implements TableCellRenderer {
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
JTextField editor = new JTextField();
if (value != null) {
editor.setText(value.toString());
}
if (game.getCur_color().getKey() == 0) {
editor.setBackground(Color.WHITE);
}
else if (game.getCur_color().getKey() == 1) {
editor.setBackground(Color.RED);
}
else if (game.getCur_color().getKey() == 2) {
editor.setBackground(Color.GREEN);
}
else if (game.getCur_color().getKey() == 3) {
editor.setBackground(Color.BLUE);
}
else if (game.getCur_color().getKey() == 4) {
editor.setBackground(Color.YELLOW);
}
return editor;
}
}
@SuppressWarnings("serial")
class MyTableModel extends AbstractTableModel {
public int getColumnCount() {
return NUM_COLS;
}
public int getRowCount() {
return NUM_ROWS;
}
public Object getValueAt(int row, int col) {
return null;
}
}
}
俄罗斯方块类:
public class Tetris
{
int NUM_ROWS = 20;
int NUM_COLS = 10;
int grid[][];
int cur_row;
int cur_col;
Pieces cur_color;
Style cur_style;
Pieces next_color;
Style next_style;
boolean over;
public Tetris()
{
grid = new int[10][20];
for(int i = 0; i < 10; i ++)
{
for(int j = 0; j < 20; j ++)
{
grid[i][j] = Pieces.BLANK.getKey();
}
}
next_color = Pieces.createColor();
next_style = Style.createStyle();
over = false;
create_Piece();
}
public void createPiece(){...}
public void setPiece(){...}
public void removeRow(){...}
}
连同 moveLeft、moveRight、moveDown、rotateLeft、rotateRight、printGame 以及所有字段的 getter 和 setter。Tetris 类中的所有方法都在控制台中进行了测试,并且可以正常工作。这是我到目前为止的输出。每次颜色都不同,我很确定我知道为什么,但是我很难考虑如何根据俄罗斯方块类中创建的网格数组为每个单元格着色。
