DoMenu woes

[sbonham]

I'm stuck...

Code: Select all

on mouseUp
   select img "girl.png"
   doMenu "Duplicate Objects" of Menu "Edit"
   put "GHOST" & the short name of the selected image into NewShortName
   set the short name of the selected image to NewShortName
   set the ink of img NewShortName to "blend"
   set the blendLevel of image NewShortName to 50
   show image "GHOSTgirl.png" at the loc of image "girl.png"
   hide image "girl.png"
end mouseUp

The code above selects the image "girl.png" and NOTHING else...
suggestions?

Hi Steve,

your script does not even compile. Here some reasons for the failing:
1. there is nothing like "the selected image" only "the selectedobject"
2. From the dictionary about "doMenu":
...
The doMenu command is not implemented for all menu items. This command is included in LiveCode for compatibility with imported HyperCard stacks.
...
So "Duplicate Objects" obviously is not supported, that's why you only have ONE image in the end.
3. You cannot "set the short name of img xyz" only "set the name of img xyz". Illogical but true

This does work, and don't forget to LOCK SCREEN, so the user will not see what is going on:

Code: Select all

on mouseUp
   lock screen

   ## This is what the "Duplicate Objects" menu actually does:
   clone img "girl.png"
   put "GHOST" & the short name of last img into NewShortName

   ## New and cloned objects always have the highest layer number:
   set the name of last img to NewShortName
   set the ink of img NewShortName to "blend"
   set the blendLevel of image NewShortName to 50

   ## "show xyz AT..." does not work -> error
   ## show image "GHOSTgirl.png" at the loc of image "girl.png"

   ## You want to:
   set the loc of last img to the loc of image "girl.png"
   hide image "girl.png"
   unlock screen
end mouseUp

Thank-you Klaus!
I'll try this now!

I didn't know about the "CLONE" option!
That's Awesome! Worked beautifully!!!

Problems with delete image VarName...

Klaus, I've got the Ghosts coming in fine and now want to delete them by gradually deleting them as their trail lengthens...
Here's what my code looks like - but it is not working properly I'm thinking it's because I'm using a variableName (Ghost2Delete)...

Field "Ghosts" contains the file names of the images that were cloned... so that they can be deleted after they have left a "trail" of images... -- after 10 are displayed in slightly different locations (a path) the first - (and successive ones eventually) disappear(s)...

but - nothing is disappearing... since this is not a "last image" case I'm wondering what the solution might be...

Code: Select all

put 1 into lineNo
   put the number of lines of fld "ghosts" into Reps
   repeat Reps
      put 1 into itemNum
      put the number of items of line LineNo of fld "Ghosts" into Reps2
      repeat Reps2
         put item itemNum of line LineNo of fld "Ghosts" into Ghost2Delete
         delete image Ghost2Delete 
         put itemNum
         add 1 to ItemNum
      end repeat
      add 1 to lineNo
   end repeat
   
 put empty into fld "Ghosts"

Hi Steve,

do you want to delete the GHOST images or the original images?
I guess the GHOST images, right? Then you need to:

Code: Select all

...
LOCK SCREEN
...
repeat Reps2
   put item itemNum of line LineNo of fld "Ghosts" into Ghost2Delete
   put "GHOST" & Ghost2Delete  into img2Del
   if there is an img img2Del then
          delete image img2Del
   end if 
 ...
UNLOCK SCREEN
...

Not?
