III. Project git commit record

IV. Preliminary investigation

We are looking for Sokoban games in 4399, found that roughly follows function

So we want to achieve the basic functions are:

1. To achieve the function keyboard, arrow keys

2. clearance judge whether the game functions

3. Support off function is selected, may be selected from 1 to 50 Off

4. Add the game background music

5. Supports "undo" function, that is, go back and start again and function

Fives.

VIII. The key codes

Step regret Code:

    public void previousMove() {
        if(moveStack.isEmpty()){
            return;
            }
        GameMove previous=moveStack.pollLast();
        if(previous!=null) {
            boy.reset(previous.boyX,previous.boyY,previous.boyDirection);
            if(previous.moveBox!=null) {
                Box b=previous.moveBox;
                b.moveTo(previous.boxX, previous.boxY);
                GameMapCell homeCell=map.get(b.x, b.y);
                if(homeCell.type==GameMapCell.TYPE_HOME) {
                    b.setWin();
                }
            }
        }else {
            this.setLevel(this.level);
        }
    }

人物及箱子移动代码（以向左移动为例）

    private void handleLeft() {
        int bx = boy.x, by = boy.y;
        // 获取boy前面类型
        GameMapCell cell = map.get(bx-1, by);
        if (cell == null) {
            return;
        }
        switch (cell.type) {
        case GameMapCell.TYPE_BLOCK:
            // 障碍物，不能移动
            return;
        case GameMapCell.TYPE_GRASS:
        case GameMapCell.TYPE_HOME:
            // 草地和目标位置上是否有箱子
            Box box = getBoxAt(cell.x, cell.y);
            if (box == null) {
                // 没有，则boy移动
                boy.moveLeft();
                moveStack.add(GameMove.of(boy));
            } else {
                // 有，判断盒子前面有什么
                if (canBoxMoveIn(box.x-1, box.y)) {
                    box.moveLeft();
                    boy.moveLeft();
                    moveStack.add(GameMove.of(boy,box));
                }
            }
            break;
        }
    }

九. 扫描结果及改正

扫描结果：

改正结果：

十. 总结

不足：

　　悔一步功能只能够返回未到达目标的箱子，如若箱子已变成“win”状态，则不会再返回上一步（游戏难度降低）：

　　界面编程仅用eclipse实现，界面些许简陋

展望：

　　尝试推箱子暴力破解

　　尝试NetBeans或JavaFx编程界面
