Revealing sprites dynamically

Question

Hi,
I've adapted the built-in behaviour 'Turn towards mouse' so
that a ruler appears on my stage when the 'r' key is down and the
user clicks and holds the mouse button down. It rotates around the
point at which it was placed, and follows the mouse as long as the
'r' key (and mouse button) is down. What I want to add to this
behaviour is revealing the ruler image dynamically as the pointer
drags away from the point of origin. In other words, the finished
effect will be to click anywhere on the stage and effectively
'draw' a ruler in the direction and to the length desired. Can
anyone point me in the right direction?
Many thanks,
TzK.

Answer 1

it works now. - thank you. oh man. lingo is soo
time-consuming if you don´t do it regularly... :(
but at least i´m able to be pleased with the little
successes....
that´s the code that worked for me, if someone else
should be searching for this:
vFolder = the moviePath --startupFolder
gFolderList = baFolderList(vFolder) -- list subfolders of
startupFolder
gFolderPosList = [point(100, 100),point(100, 200),
point(100, 300), point(100, 300), point(100, 300), point(100, 300)]
-- erase all fields on startUp to avoid thousands of fields
later.. ;)
repeat with vEraser = 1 to (the number of members of castlib
"internal")
if member(vEraser, castlib "internal").type = #field then
member(vEraser).erase()
end if
end repeat
repeat with vFolderName in gFolderList
vFieldMember = new(#field) -- create new field
vFieldMember.name = vFolderName & "member" -- give field
same name as the folder has
vString = ""
put RETURN & vFolderName after vString
delete char 1 of vString -- initial RETURN
vFieldMember.text = vString -- put name of the field/folder
into field
vSprite = new(#sprite) -- create new sprite (necessary for
displaying on stage)
sprite(vSprite).member = member(vFieldMember) -- fill
sprites with field-members
actPos = gFolderList.getPos(vFolderName) -- temp. shortening
of that listPos-thing
channel(actPos).makeScriptedSprite(member(vFolderName &
"member"), gFolderPosList.getAt(actPos))
end repeat
