c#扫雷游戏
一、C#实现扫雷
1、在form中
BombClass bombClass = new BombClass();
/*布雷按钮事件*/
private void initBombBtn_Click(object sender, EventArgs e)
{
bombClass.InitBombData();
bombClass.winHandle = bombPanel.Handle;
bombPanel.Width = bombClass.Width;
bombPanel.Height = bombClass.Height;
bombClass.BombDraw(); //使用方法一画雷盘
//bombClass.DispBomb(); //使用方法二画雷盘
}
/*雷盘的鼠标点击事件：方法一 */
private void bombPanel_MouseClick(object sender, MouseEventArgs e)
{
//获取鼠标点击时的位置
int row = e.Y / (bombClass.CellSize + 1);
int column = e.X / (bombClass.CellSize + 1);
//如果已经点击过了
if (bombClass.BombDataFlag[row, column] == 1)
return;
//可以显示标志
bombClass.BombDataFlag[row, column] = 1;
//如果踩到的方格是数字
if (bombClass.BombData[row, column] > 0)
{
;
}
else if (bombClass.BombData[row, column] == BombClass.BombInt)
{
bombClass.ShowAllBomb();
MessageBox.Show("踩到地雷了！");
return;
}
else if (bombClass.BombData[row, column] == 0)
{
//bombClass.NullDepthFindFirst(row, column);//深度优先搜索
bombClass.NullWidthFindFirst(row, column); //广度优先搜索
}
if (bombClass.CheckFinishFirst())
{
MessageBox.Show("成功！");
bombClass.ShowAllBomb();
}
else
bombClass.BombDraw();
}
/*扫雷panel重绘事件*/
private void bombPanel_Paint(object sender, PaintEventArgs e)
{
if (bombClass.BombStartFlag)
{
if (bombClass.winHandle == null)
bombClass.winHandle = bombPanel.Handle;
