Efek Gerakan Bintang (Star Motion) Pada Visual Basic

Source code berikut untuk membuat efek Star Motion pada background form di Visual Basic. Bintang-bintang berwarna-warni bergerak menyebar secara random di tengah-tengah form.
Buat 1 project dengan :
1 Form
1 Timer
Copy source code berikut pada Form :

Dim X(100), Y(100), Z(100) As Integer
Dim tmpX(100), tmpY(100), tmpZ(100) As Integer
Dim K As Integer
Dim Zoom As Integer
Dim Speed As Integer

Private Sub Form_Activate()
Speed = -1
K = 2038
Zoom = 256
Timer1.Interval = 1

For i = 0 To 100
X(i) = Int(Rnd * 1024) - 512
Y(i) = Int(Rnd * 1024) - 512
Z(i) = Int(Rnd * 512) - 256
Next i
End Sub

Private Sub Timer1_Timer()
For i = 0 To 100
Circle (tmpX(i), tmpY(i)), 5, BackColor
Z(i) = Z(i) + Speed
If Z(i) > 255 Then Z(i) = -255
If Z(i) < -255 Then Z(i) = 255 tmpZ(i) = Z(i) + Zoom tmpX(i) = (X(i) * K / tmpZ(i)) + (Form1.Width / 2) tmpY(i) = (Y(i) * K / tmpZ(i)) + (Form1.Height / 2) Radius = 1 StarColor = 256 - Z(i) Circle (tmpX(i), tmpY(i)), 5, RGB(StarColor, StarColor, StarColor) Next i End Sub
