shrink in the way

[Samuele]

Hi, I'm trying to show a field in the middle of the stack and after 2 seconds move it

Code: Select all

into the points of graphic "someGraphic"

and till here it's okay, but i wanted to add something else, that in the mean time that the field is going in the path of the graphic it also shrinks gradually, till it arrives to the 'end' of the graphic and it's still visible, is it possible?
Thanks!

Hi Samuel

is it possible?

You may resize field in a loop using the num of points

Sorry, couldn't quite understand, what points do you mean? of the graphic?
something like: for every 2 points in the graphic take it down a notch? (obviously this can't be a script)
Thanks!

In the manner of what Jean-Marc mentioned, think about this. When you move an object to the points of a graphic, say, LC moves to successive lines of the "points" (a property) of that graphic.

But what you want to do is to reduce the field every time it reaches a new point. So work on this:

I never use the "move" command, except for play.

But I wonder if it is possible to do what the OP wants, not with the heavy-handed stack I just posted, but by trapping say, the "locationChanged" message while moving through the points of a graphic. One would have to remember the most recent point and only reduce the size when that changes, otherwise the control would reduce too fast, I think.

Hmmm.

alright, thanks, i don't fully understand the script, but I'm trying, is there a way to do it without causing to the stack to stop for the moving (probably without the wait) Thanks!

Not sure what you mean. How does a stack "stop"? When you click the button, the square field tracks the graphic, and shrinks just a bit at each point. What did you intend, or wish for?

You say you don't understand the script, have you tried stepping through the handler? Place a breakpoint at line 9, where the width is changed. Now manually step through. You can see that the field jumps to successive points of the graphic, and once there, shrinks just a little. It then goes to the next point...

Remember that the "points" of a graphic is a return delimited list; each line in that list contains one point.
