Ampel programmieren

[michapitbull]

habe jjetzt rumprobiert aber ich krieg die verdammte ampel einfach nicht zum laufen...sie bleibt immer bei rot stehen !
hier mein Quellentext:

Delphi-Quellcode:

unit Unit2;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ExtCtrls;

type
  TForm2 = class(TForm)
    Shape1: TShape;
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    SRot   : TShape;
    SGelb  : TShape;
    SGruen : TShape;
    Timer1  : TTimer;

    procedure Button3Click(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);

  private
    Phase: Integer;
    Zeit: Integer;
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form2: TForm2;

implementation

{$R *.dfm}

procedure TForm2.Button1Click(Sender: TObject);
begin
 case Phase of
    1: begin
         SRot.Brush.Color:= clRed;
         SGelb.Brush.Color:= clBlack;
         SGruen.Brush.Color:= clBlack;
         Phase:= Phase + 1;
       end;
    2: begin
         SRot.Brush.Color:= clRed;
         SGelb.Brush.Color:= clYellow;
         SGruen.Brush.Color:= clBlack;
         Phase:= Phase + 1;
       end;
    3: begin
         SRot.Brush.Color:= clBlack;
         SGelb.Brush.Color:= clBlack;
         SGruen.Brush.Color:= clGreen;
         Phase:= Phase + 1;
       end;
    4: begin
         SRot.Brush.Color:= clBlack;
         SGelb.Brush.Color:= clYellow;
         SGruen.Brush.Color:= clBlack;
         Phase:= 1
end;
end;
end;

procedure TForm2.FormCreate(Sender: TObject);
begin
  Phase:= 1;
  Zeit:= 1;
end;

{ Rr }

procedure TForm2.Button3Click(Sender: TObject);
begin
close;
end;

procedure TForm2.Timer1Timer(Sender: TObject);
begin
begin
  Zeit:= Zeit + 1;
  case Zeit of
    1..5 : Phase:= 1;
    6    : Phase:= 2;
    7..11: Phase:= 3;
    12   : begin
             Phase:= 4;
             Zeit:= 0;
           end;
end;

end;
end;
end.
