Here's what i got :

1 form (form1)

1 Timage Object (img)

1 timer (timer1)

1 Button (btn)

1 variable named X

----
Button code:
if timer1.enabled then
timer1.enabled:=false
else
timer1.enabled:=true;
-----
timer code:
var x:integer;

timer1.interval:=20;

x:=img.width

if (x>=10) and not(x<=215) then
begin
img.width:=img.width + 1;
end else begin
img.width := img.width - 1;
end;
-------

As you can see im trying to increase img's width
and decrease it back to custom size (in both cases).
(in infinite loop)

Well , for some reason it justs goes from its current position to 10.

Can someone fix my code ?

thanks for reading my thread :>

The easiest way is to store the direction of the change in the X variable. If the width reaches maximum value, you switch the direction around, until it reaches the minimum value. In code:

  Image1.Width := Image1.Width + X;
  if Image1.Width = 215 then
    X := -1;
  if Image1.Width = 10 then
    X := 1;

For this trick to work, X must be a field in the form containing the OnTimer event. Also X must be set to 1 in the OnCreate() of the form.
