Wie man einen Spielknopf wieder herstellt?

Question

Ich versuche, eine Schaltfläche zum erneuten Abspielen für mein Spiel in einer separaten Windows-Form zu machen, aber ich bin mir nicht sicher, wie ich das neue Formular aufrufen soll. Kann mir jemand in die richtige Richtung zeigen?

Hier ist mein Form1 Code:

namespace BrickO1 
{ 
public partial class Form1 : Form 
{ 
    private const int kNumberOfTries = 3; 

    public int rounds; 
    private Ball TheBall = new Ball(); 
    private Paddle ThePaddle = new Paddle(); 
    private Paddle TheOtherPaddle = new Paddle(); 
    private PlayAgain playagain = new PlayAgain(); 

    // private System.Windows.Forms.Timer timer1; 

    private Score TheScore = null; 
    private Score TheOtherScore = null; 
    private Thread oThread = null; //thread is used to run sounds independently 

    [DllImport("winmm.dll")] 
    public static extern long PlaySound(String lpszName, long hModule, long dwFlags); 
    //method PlaySound must be imported from the .dll file winmm 



    public Form1() 
    { 
     InitializeComponent(); 

     ThePaddle.Position.X = 5; 
     ThePaddle.Position.Y = this.ClientRectangle.Bottom - ThePaddle.Height; 

     TheOtherPaddle.Position.X = 5; 
     TheOtherPaddle.Position.Y = 0; 
     // this.ClientRectangle refers to the current container (the instance of Form1) 

     TheBall.Position.Y = this.ClientRectangle.Bottom - 200; 

     TheScore = new Score(ClientRectangle.Right - 30, ClientRectangle.Bottom - 40); 
     TheOtherScore = new Score(ClientRectangle.Right - 30, ClientRectangle.Bottom - 370); 
     //positions the score - 0 at this moment 

     // choose Level 
     SpeedDialog dlg = new SpeedDialog(); 
     /* makes sure that, if the DialogResult property of the button "OK" is on, 
     the SpeedDialog form appears and stays on the screen, and timer's Interval 
     gets an appropriate value */ 
     if (dlg.ShowDialog() == DialogResult.OK)            
     { 
      timer1.Interval = dlg.Speed; 
      rounds = dlg.SelectedLength; 
     } 
    }

       of the executable file: Application.StartupPath */

     oThread.Abort(); //aborts the tread playing sound 
    }

     TheOtherScore.Reset(); 
    } 
    private void Form1_Load(object sender, EventArgs e) 
    { 

    } 
} 
} 

Und meine PlayAgain Klasse:

namespace BrickO1 
{ 
public partial class PlayAgain : Form1 
{ 
    public PlayAgain() 
    { 
     InitializeComponent(); 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     init(); 
    } 
} 
}

Wenn Sie eine neue Form machen wollen, dann für das Formular ein neues Objekt erstellen.

Form1 f1=new Form1(); 
f1.Show();
