Scrolling text -- like movie credits

[marksmithhfx]

Anyone have a suggestion for scrolling a list of text items (like movie credits) vertically across a blank card... ok, I suppose I'll need a container but haven't decided if one is better than another. I'd probably want it to be invisible anyway (no borders etc).

Thanks

vertically across a blank card

Presumably you mean vertically UP a blank card?

The scroll of a field can still be set even if the scrollbar properties are turned off.

This one "scrolls" an image of text/

This one does exactly the same but with a text field, and comes in at less than 1%
of the size of the former.

Code: Select all

on mouseUp
   set the top of fld "REP" to 10
   put the bottom of fld "REP" into BUM
   repeat until BUM < 1
      set the bottom of fld "REP" to BUM
      subtract 1 from BUM
      wait 2 ticks
   end repeat
end mouseUp

Rocket science.

A little more compact:

Code: Select all

on mouseUp
   repeat until the scroll of fld 1 >=  (the number of lines of fld 1 * the textHeight of fld 1)  - the height of fld 1
      set the scroll of fld 1 to the scroll of fld 1 + 1
      wait 1 millisec --your call here
   end repeat
end mouseUp

Had some wild dreams last night.

Code: Select all

on mouseUp
   put fld "REP2" into fld "REP"
   do rowSCALE
   put 1 into WIPEOUT
   repeat until WIPEOUT > 50
      delete line 1 of fld "REP"
      do rowSCALE
      add 1 to WIPEOUT
      --wait 1 tick
   end repeat
end mouseUp

on rowSCALE
put 1 into RROW
repeat until RROW > 50
   set the textSize of line RROW of fld "REP" to (RROW + 7)
   add 1 to RROW
end repeat
end rowSCALE

That is adorable, Richmond.

That is adorable,

It might be if it weren't so jerky.

[dunbarx]

Ah.

It might be if it weren't so jerky.

I didn't actually run it. Lets play around for a bit...

Craig

[dunbarx]

Richmond.

Tried a few experiments.

There is an intrinsic problem with doing this in a single field, in that If I set the "fixedLineHeight" to true, or set the textSize of a particular line, LC adjusts the visible text to accommodate those property changes. This always appears as jerkiness, whether I then scroll the field or whatever.

Thinking...

Want to try this?

No!

Busy building bookshelves.

a stack of fields

Strewth! Give me strength.

[dunbarx]

I had thought of a stack of fields, each with its own text properties, and loaded field by field (line by line) from below with the contents of some source text. Not sure this would be any smoother.

I think scrolling is required. Just trying to smooth it with all the other shenanigans going on.

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.

Just butting in to remark that all solutions so far will lock up the CPU until the repeat completes. Add a "with messages" or, better, use "send in time".
