Question

我正在写一个让两个坦克互相撞击的程序。我已经写了除了结束游戏的火之外的所有方法。到目前为止

public class Tank {
    Tank() {
        int xPos, yPos;
        char direction;
        boolean loaded = 0;
    }

    public void move(Tank currentPlayer) {
        if (yPos<=4 && yPos>=0) {
            if (xPos<=4 && xPos>=0) {
                if (currentPlayer.direction == 'u') {
                    currentPlayer.yPos--;
                }
                if (currentPlayer.direction == 'd') {
                    currentPlayer.yPos++;
                }
                if (currentPlayer.direction == 'l') {
                    currentPlayer.xPos--;
                }
                if (currentPlayer.direction == 'r') {
                    currentPlayer.xPos++;
                }
            }
        }
    }

    public void turn(boolean bool, Tank currentPlayer) {
        if (currentPlayer.direction == 'u') {
            currentPlayer.direction ='r';
        }
        if (currentPlayer.direction == 'd') {
            currentPlayer.direction = 'l';
        }
        if (currentPlayer.direction == 'l') {
            currentPlayer.direction ='u';
        }
        if (currentPlayer.direction == 'r') {
            currentPlayer.direction ='d';
        }
    }

    public void load(Tank currentPlayer) {
        currentPlayer.loaded=true;
    }

    public int fire(Tank currentPlayer, Tank jim) {
        // ???
    }    
}

如何完成我的计划？任何帮助将不胜感激。

你需要一个吸气剂来测量水箱的x位置，y位置和当前方向。例如：

public int getX();
public int getY();
public char getOrientation();

通过调用这些方法，您应该获得坦克的x位置，y位置和方向。然后检查命中。你知道你面临的方向。因此，如果你正面朝上，看看另一个坦克是否与你在同一个x上，并且他们的y高于你的。

int otherX = jim.getX();
int otherY = jim.getY();

switch (currentPlayer.getOrientation())
{
    case 'u':
        //Check if you're in same x
        //Check if above player
        break;
    case ... etc.
}

然后在击中的情况下，换句话说，如果满足条件。游戏应以currentPlayer胜利结束。
