【开始】按钮的事件是设置label的显示文本、开始计时和时间间隔，并调用生成方块的方法的函数。主要代码如例程3-3所示。 例程3-3 【开始】按钮事件的代码 private void buttonl_Click(object sender,System.EventArgs e) { this.Start(); this.textBoxl.Focus(); } private void Start() { this.block=null; this.nextBlock=null; this.labe11.Text="手速: 0"; this.labe12.Text="块数: 0"; this.labe13.Text="行数: 0"; this.labe14.Text="级别: "+this.startLevel; this.level=this.startLevel; this.timerl.Interval=500-50*(level-1); //方块生成的时间间隔 this.paused=false; this.failed=false; this.pane11.Invalidate(); this.pane12.Invalidate(); this.nextShapeNO=0; this.CreatBlock();//生成当前方块 this.CreatNextBlock();//生成下个方块 this.timerl.Enabled=true; this.atStart=DateTime.Now; this.pauseTime=new TimeSpan(0); }

在【开始】按钮事件中调用了声称当前方块函数CreatBlock()和生成下个方块的函数CreateNextBlock()。在这两个函数中定义了方块出现的位置、颜色，随机生成方块的形状，并调用Block()函数在相应位置显示。这两个函数的代码如例程3-4所示。 例程3-4 CreateBlock和CreatNextBlock函数代码 private bool CreatBlock() { point firstPos; Color color; if(this.nextShapeNO==0) { Random rand=new Random(); this.nextShapeNO=rand.Next(1,8); } switch(this.nextShapeNO) { case 1://田 firstPos=new Point(4,0); color=Color.Turquise; break; case 2://一 firstPos=new Point(3,0); color=Color.Red; break; case 3://土 firstPos=new Point(4,0); color=Color.Silver; break; case 4://z firstPos=new Point(4,0); color=Color.LawnGreen; break; case 5://倒z firstPos=new Point(4,1); color=Color.DodgerBlue; break; case 6://L firstPos=new Point(4,0); color=Color.Yellow; break; default://倒L firstPos=new Point(4,0); color=Color.Salmon; break; } if(this.block==null) { block=new Block(this.pane11,9,19,25,this.nextShapNO,firstPos); } else { if(!block.GeneBlock(this.nextShapeNO,firstPos,color)) { return false; } } block.EraseLast(); block.Move(2); return true; } private void CreateNextBlock() { Random rand=new Random(); this.nextShapeNO=rand.Next(1,8); point firstPos; Color color; switch(this.nextShapeNO) { case 1://田 firstPos=new Point(1,0); color=Color.Turquise; break; case 2://一 firstPos=new Point(0,1); color=Color.Red; break; case 3://土 firstPos=new Point(0,0); color=Color.Silver; break; case 4://z firstPos=new Point(0,0); color=Color.LawnGreen; break; case 5://倒z firstPos=new Point(0,1); color=Color.DodgerBlue; break; case 6://L firstPos=Point(0,0); color=Color.Yellow; break; default://倒L firstPos=new Point(0,0); color=Color.Salmon; break; } if(nextBlock==null) nextBlock=new Block(this.pane12,3,1,20,this.nextShapNO,firstPos,color); else { nextBlock.GeneBlock(this.nextShapeNO,firstPos,color); nextBlock.EraseLast(); }
