Messagebox不會停止顯示

Question

我正在嘗試編寫此代碼，以便在點擊開始時從"FORM1"開始Obj將調用此方法來使用並啓用timer1。

當我點擊開始按鈕犬的圖像將啓動但消息框一直顯示和dogpic到達球門線後不停止移動到右側，直到達到X= 620那麼它就會顯示消息框" win"

class dog 
{ 
    public int startpost; 
    public int TrackLenght = 620; 
    public PictureBox dogpic = null; 
    public int Location = 0; 
    public Random random=new Random(); 

    public void ResetStart() 
    { 
     dogpic.Location = new System.Drawing.Point(40, startpost); 
    } 

    public bool testrun() 
    { 
     Point p = dogpic.Location; 

     if (p.X < TrackLenght) 
     { 
      int distance = random.Next(5); 

      p.X = p.X + distance; 
      dogpic.Location = p; 
      Location = dogpic.Location.X; 
      return false; 
     } 
     else 
     { 
      MessageBox.Show(dogpic.Name + " win"); 

      return true; 
     } 
    } 
} 

Answer 1

//suppose dog1 is an instance of your dog class 
//here is the Tick event handler of your timer1 
private void timer1_Tick(object sender, EventArgs e){ 
    timer1.Enable = !dog1.testrun(); 
} 

Answer 2

您可以使用計時器。

timer.Interval=5000; 
timer.Enabled=true; 
MessageBox.Show(dogpic.Name + " win"); 

您可以將其與tck事件相關聯。

private void timer_Tick(object sender,EventArgs evt) { 
    timer.Enabled=false; 
} 

Answer 3

嘗試正在重置p.X你贏了。

沒有看到它你的代碼，但我認爲你應該做這樣的事情：

public bool testrun() 
    { 

     Point p = dogpic.Location; 

     if (p.X < TrackLenght) 
     { 
      int distance = random.Next(5); 

      p.X = p.X + distance; 
      dogpic.Location = p; 
      Location = dogpic.Location.X; 
      return false; 
     } 
     else 
     { 

      MessageBox.Show(dogpic.Name + " win"); 
      ResetStart() 
      return true; 
     }}}

在按一下按鈕，你應該調用ResetStart（）函數，這將使定時器，做你的工作，並在到達終點它應該禁用定時器。

class dog 
{ 
    public int startpost; 
    public int TrackLenght = 620; 
    public PictureBox dogpic = null; 
    public int Location = 0; 
    public Random random=new Random(); 

    public void ResetStart() 
    { 
     dogpic.Location = new System.Drawing.Point(40, startpost); 
     timer.Enabled=true; 
    } 

    public bool testrun() 
    { 
     Point p = dogpic.Location; 

     if (p.X < TrackLenght) 
     { 
      int distance = random.Next(5); 

      p.X = p.X + distance; 
      dogpic.Location = p; 
      Location = dogpic.Location.X; 
      return false; 
     } 
     else 
     { 
      MessageBox.Show(dogpic.Name + " win"); 
      timer.Enabled=false;  
      return true; 
     } 
    } 
} 

希望它能工作。
