Taquin

puzzle15.png

Le taquin est un casse-tête avec des pièces glissantes qui consiste en un cadre de tuiles carrées numérotées dans un ordre aléatoire avec une tuile manquante. Le but du jeu consiste à replacer les tuiles dans l'ordre à l'aide de glissements qui utilise la place vide.

Créer le code

  • Créer une nouvelle application IHM avec la fiche Form1
  • Changer le titre de Form1 en 15Puzzle'.
  • Ajouter la nouvelle unité unitGameBoard.pas
  • Créer le gestionnaire d'événement OnCreate pour la fiche, en cliquant sur votre fiche, utiliser l'inspecteur d'objets, l'onglet Evénement, sélectionner OnCreate et cliquer sur le bouton [...] ou double-cliquer directement sur la fiche.
  • Ajouter le code suivant :
procedure TForm1.FormCreate(Sender: TObject);
var
  i : Integer;
  aButton: TButton;
  point:TPoint;
begin
  Randomize;
  Puzzle15:= TGameBoard.Create;
  i := 1;
  while i < 16 do
    begin                              //create 15 Buttons
      aButton:=TButton.Create(Self);   //create Button, Owner is Form1, where the button is released later
      aButton.Parent:=Self;            //determine where it is to be displayed
      aButton.Caption:=IntToStr(i);    //Captions of the buttons
      aButton.Width:=aButton.Height;   //Width should correspond to the height of the buttons
      point := Puzzle15.ButtonPlace(aButton.Caption);
      aButton.Left:= point.x* aButton.Width;    //Distance from left
      aButton.Top := point.y* aButton.Height;
 
      aButton.OnClick:=@aButtonClick; //the event handler for the button -> will be created yet
      inc(i);
    end;
  Self.Height:=aButton.Height*6;      //Height of the form should correspond to the height of the buttons
  Self.Width:=aButton.Width*6;        //Width of the form to match the width of all buttons
end;
  • Créer dans l'inspecteur d'objet, le gestionnaire pour l'événement FormDestroy, en cliquant sur le bouton [...].
  • Ajouter le code suivant dans le gestionnaire :
procedure TForm1.FormDestroy(Sender: TObject);
begin
  FreeAndNil(Puzzle15);
end;
  • Maintenant vous devez créer le gestionnaire d'événement pour les clics de bouton.
  • Dans l'éditeur de source, en entrant dans la section private de votre classe TForm1.
  • Ajouter la procédure aButtonClick(Sender: TObject); and ensuite pressez la touche Ctrl+ Shift+c (la complétion de code devient active et crée la procédure TForm1.aButtonClick(Sender: TObject);.
  • Coller le code suivant :
procedure TForm1.aButtonClick(Sender: TObject);  //the event handler for the button
var
  i:integer;
  point : TPoint;
begin
  if (Sender is TButton) and                     //called the event handler of a button out?
     TryStrToInt(TButton(Sender).Caption, i)       //then try to convert the label in a integer
    then
      begin
        if Puzzle15.CanMove(TButton(Sender).Caption) then
          begin
            point := Puzzle15.Change(TButton(Sender).Caption);
            TButton(Sender).Left:= point.x* TButton(Sender).Width;    //Distance from left
            TButton(Sender).Top := point.y* TButton(Sender).Height;
          end;
      end;
end;
