Scrolling text -- like movie credits

Our current issues are that we are jerks.

If you want a smooth "Star Wars" like credit scene, check Hermanns excellent stack here:

Heh. Well in that case we should send you in time too.

But I don't handle messages well.

A Kludge and a half would be to create and load thin transparent horizontal fields at the bottom of a defined area that move upward at some nice rate, and reduce their textSize along the way. The height of each field has to diminish as well so that the spacing seems "right". They are deleted at the top. I am sure this would be smooth, and look exactly like a field with that dynamic attribute.

But it is a heavy kludge, and though simple to build, I am sticking for the moment on how to make a single field do it.

vertically across a blank card

Presumably you mean vertically UP a blank card?

Correct, across can be up

Those bookshelves seem to get more and more %^&*()
the higher I climb on the ladder, but it is in fact an illusion as the tape measure
rarely lies.

AND, should you think that that has no relevance to the matter under consideration, think again.

Lol -- you guys are two funny. Anyway, on your first example, very clever but it locked up my computer. I had to force quit to get it to listen to me

Waaaaaaahhhhh

Please do. Bottom to top works fine. I don't need the 3d effect. Winner gets a free copy of the program (probably saving you, ohhh, maybe $2.99)

Did you take a look at Hermann's stack?

That's due to the repeat loops I mentioned. I bet if you watch the Activity Monitor you'll see that LC is using 100% CPU time and all other apps are frozen.

All you really need is a field containing the text, spaced and styled however you want. Leave some blank lines between each credit and enough blank lines at the bottom to push all the text out of view. Then (untested):

Code: Select all

on startScroll
  doScroll
end startScroll

on doScroll
  set the scroll of fld "credits" to the scroll of fld "credits" + 2
  send "doScroll" to me in 10 milliseconds
end doScroll

Adjust the scroll amount and the time delay until it looks right. You should provide an exit clause too if the user wants to stop or leave the card. Delete all pending messages to stop.

Code: Select all

on stopScroll
  repeat for each line L in the pendingMessages 
    if L contains "doScroll" then cancel item 1 of L
  end repeat 
end stopScroll

No, I missed it the first time. Going to look at it now...

I think Hermann's stack is gone now.
But here's another version based on use of browser widget, using css taken from here: https://codepen.io/yukulele/pen/KsCIi
It scrolls very smoothly.

Impressive indeed!
