Membuat anaimasi kurva dengan delphi 6.0

Pertama anda jalankan Delphi 6.0
Jadikan Form delphi seperti gambar di bawah ini

Setiap komponen tambah koding seperti di bawah ini    ::

unit AnimasiKurvaU;

interface

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

type
  TForm1 = class(TForm)
    Shape1: TShape;
    Timer1: TTimer;
    Button1: TButton;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
 r,d,c,x,y,theta,thetaf:real;
 a,xc,yc,b,xp:integer;
implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
a:=100;xc:=300;yc:=200;b:=100;
thetaf:=0.0;
d:=2.*PI;xp:=0;
theta:=d;
c:=1/a; timer1.Enabled:=true;
shape1.Visible:=false;
end;


              procedure TForm1.Timer1Timer(Sender: TObject);
              begin
              if (thetaf<(8*theta))then
              begin
              r:=b+sin(thetaf)/cos(thetaf);
              x:=r*cos(5*thetaf);
              y:=r*sin(7*thetaf);
              if xp=0 then
              canvas.Pixels[trunc(xc+x),trunc(yc+y)]:=clred;
              if xp=1then
              begin
              shape1.Left:=trunc(xc+x) ;
              shape1.Top:=trunc(yc+y);
              end;
              thetaf:=thetaf+c;
              end;
              if (thetaf>(8*theta))then
              begin
              r:=b+sin(thetaf)/cos(sqr(thetaf));
              x:=r*cos(thetaf);
              y:=r*sin(thetaf);
              if xp=0 then
              canvas.Pixels[trunc(xc+x),trunc(yc+y)]:=clred;
              if xp=1 then
              begin
              shape1.Left:=trunc(xc+x);
              shape1.Left:=trunc(yc+y);
              end;
              thetaf:=thetaf+c;
              end;
               end;




procedure TForm1.Button2Click(Sender: TObject);
begin
xp:=1;
shape1.Visible:=true;
a:=100; xc:=300; yc:=200; b:=100;
thetaf:=0.0;
d:=2*PI;
thetaf:=d;
c:=1/a; timer1.Enabled:=true;
end;
end.

SEMOGA BERMANFAAT
