坦克游戏JavaFX中的运动

如何解决坦克游戏JavaFX中的运动

我正在创建大学项目，这是一个坦克游戏，在这个游戏中，我们使用二维数组作为地图（我们可以通过更改数组的值来更改地图）并通过 KeyEvent 进行坦克遍历，我需要做一个逐块障碍（这是阵列的单元格之一），如果坦克与块相交，则无法移动。有没有办法在我的代码中做到这一点？

public class Tank extends JPanel implements ActionListener,KeyListener {
Timer tm = new Timer(1,this);
int tankX = 270,tankY = 270,velX = 0,velY = 0,direction = 1;
int bulletX = 330;
int bulletY = 330;


String[][] map = {
        {"B","S","B","B"},{"B","0","W","T","G",};
public Tank() {
    tm.start();
    addKeyListener(this);
    setFocusable(true);
    setFocusTraversalKeysEnabled(false);
}


public void paintComponent(Graphics g) {
    super.paintComponent(g);
    for (int i = 0; i < map.length; i++){
        for (int j = 0; j < map.length; j++){
            switch (map[i][j]){
                case "B":
                    g.setColor(Color.RED);
                    break;
                case "S":
                    g.setColor(Color.LIGHT_GRAY);
                    break;
                case "W":
                    g.setColor(Color.CYAN);
                    break;
                case "T":
                    g.setColor(Color.GREEN);
                    break;
                case "0":
                    g.setColor(Color.WHITE);
                    break;
            }
            g.fillRect(i*64,j*64,64,64);
        }
    }
    g.setColor(Color.BLUE);
    g.fillRect(tankX,tankY,64);
    g.setColor(Color.LIGHT_GRAY);
    if (direction == 1) {
        g.fillRect(tankX + 20,24,24); //UP
    }
    if (direction == 2) {
        g.fillRect(tankX + 20,tankY + 40,24); //DOWN
    }
    if (direction == 3) {
        g.fillRect(tankX + 40,tankY + 20,24); //RIGHT
    }
    if (direction == 4) {
        g.fillRect(tankX,24); //LEFT
    }
    g.setColor(Color.GRAY);
    g.filloval(bulletX,bulletY,14,14);
