SOLVED: gif size

[kwnz]

Is it possible to make a gif reduce size while moving to points of curve?
The gif is of a walking sheep which moves to the points of a curve (more of a straight line) starting about centre and 2 thirds down of card to bottom right of card.
The purpose is to create a perspective so the sheep gets larger as it nears the front (bottom). Thanks.
I hope I have not been to ambiguous or I see that this could go on for months.

This is entirely possible except if you are doing this sort of thing:

Code: Select all

on mouseUp
move image "ovine.gif" to the points of graphic "sexyCurve"
end mouseUp

HOWEVER, if, instead of doing a "move to the points" thing you move your image to the points (Yup: sounds mental):

First of all:

1. Put the points of your curve into the lines of a listField (or, if you are more clever than me, into an array).

2. Let's call the listField "sexyPoints".

The do this sort of thing:

Code: Select all

on mouseUp
put 1 into KOUNT
repeat until line KOUNT of field "sexyPoints" is empty
move image "ovine.gif" to line KOUNT of field "sexyPoints"
add 1 to KOUNT
------
-- in here you can do something about the size of image "ovine.gif"
------
wait 10 ticks
end repeat
end mouseUp

Although, to be honest, as you want your sheep to travel along a straight line I wouldn't bother with a curve at all:

Code: Select all

on mouseUp
   set the loc of img "ovine.gif" to 100,100
   set the width of img "ovine.gif" to 45
   set the height of img "ovine.gif" to 30
   put 2 into SKALE
   repeat until SKALE > 7
      move img "ovine.gif" to (100 * SKALE, 100 * SKALE)
      set the width of img "ovine.gif" to ((15 * SKALE) + 30)
      set the height of img "ovine.gif" to ((10 * SKALE) + 20)
      wait 4 ticks
      add 1 to SKALE
   end repeat
end mouseUp

Personally I have always thought that animated GIF images are pretty rubbishy because
they are difficult to control.

For animation I generally split an animated GIF up into its constituent frames and export them as PNG images.
(I always use GIMP for this)

Then use them as backGroundPatterns in graphic object rectangles.

This means I can go in for fine-grained control and so on in a way that is not possible with animated GIF images.

Everything is in the cardScript.

Thank you richmond62 for getting to the point (no pun intended) straight away, your answers are much more elegant. I shall try them all and certainly the repeating solution with tweaks to the size so the jump is not so noticeable. Since my post I decided to create half a dozen curves adjacent to each other and base the script on a move for each and a resize line in-between. This worked but tedious and jerky. Thanks again.

I have been mucking around with animations in LiveCode for about 12 years, so can "ruin your evening"
with quite a few ideas and examples.
