Java扫雷游戏寻找类的数量核心算法篇

今天突然间看到了扫雷游戏，想着自己实现一个，网上找了很多，大多数的用的是二维数组，今天我给大家用一维数组也就是集合来实现二维数组的功能，这篇主要写的是扫雷核心算法篇，寻找周围类的数量，不是一个完整的哦。

	}

	public void setX(int x) {
		this.x = x;
	}

	public int getY() {
		return y;
	}

	public void setY(int y) {
		this.y = y;
	}

	public boolean isL() {
		return isL;
	}

	public void setL(boolean isL) {
		this.isL = isL;
	}

	public boolean isClick() {
		return isClick;
	}

	public void setClick(boolean isClick) {
		this.isClick = isClick;
	}

	public int getNum() {
		return num;
	}

	public void setNum(int num) {
		this.num = num;
	}

}

我们可以看到以上就是全部扫雷的代码，运行后的效果如下：

而计算雷的代码如下：

private void TongjiLei() {
		
		for(int i=0;i<5;i++) {
			for(int j=0;j<5;j++) {
				int count = 0;
				int c = i*5+j;
				
				if(imgs.get(c).isL()) {
					continue;
				}
				
				//左上   (i-1)*5(j-1)
				if(i > 0 && j > 0 && imgs.get((i-1)*5+(j-1)).isL()) {
					count++;
				}
				
				//上中   (i-1)*5(j-1)
				if(i > 0  && imgs.get((i-1)*5+(j)).isL()) {
					count++;
				}
				
				//右上   (i-1)*5(j-1)
				if(i > 0 && j+1 < 5  && imgs.get((i-1)*5+(j+1)).isL()) {
					count++;
				}
				
				//左   (i-1)*5(j-1)
				if(i > 0 && j > 0 && imgs.get((i)*5+(j-1)).isL()) {
					count++;
				}
				
				//右   (i-1)*5(j-1)
				if(i<5 && j+1 < 5 && imgs.get((i)*5+(j+1)).isL()) {
					count++;
				}
				
				//左下   (i-1)*5(j-1)
				if(i+1 < 5 && j > 0 && imgs.get((i+1)*5+(j-1)).isL()) {
					count++;
				}
				
				//中下   (i-1)*5(j-1)
				if(i+1 < 5  && imgs.get((i+1)*5+(j)).isL()) {
					count++;
				}
				
				//右下   (i-1)*5(j-1)
				if(i+1 < 5 && j+1 < 5 && imgs.get((i+1)*5+(j+1)).isL()) {
					count++;
				}
				imgs.get(c).setNum(count);
				
			}
		}
	}
}

大家看到这里应该就明白了。
