That loop technique seems like too much work & that's only moving a
pixel at a time - try the below instead - it moves by the amount of
change & it's a single behavior that can be dropped onto a range of
sprites
1. places your sprites on stage in vertically increasing order
sprite n
sprite n+1
sprite n+2
etc.
these sprites will be in a range like 20-30 or something like that
- take note of the last one's number
2. Drop the behavior below onto those sprites
------------------------------------------------------------
property pSpriteNum, pSpr, pSprH, pLast
on beginSprite me
pSpriteNum = me.spriteNum
pSpr = sprite(pSpriteNum)
pSprH = pSpr.rect[4]-pSpr.rect[2] -- grab each sprite's height
pLast = 14 -- the number of the last sprite in MY range
-- put pSpriteNum, pSpr, pSprH, pLast
end
on enterFrame
now = pSpr.rect[4]-pSpr.rect[2]
if now <> pSprH then
-- then it HAS changed so ...
amt = now - pSprH -- get the amount of the change
pSprH = now -- save the new height
repeat with i = (pSpriteNum+1) to pLast
sprite(i).locV = sprite(i).locV + amt
end repeat
end if
end
------------------------------------------------------------
3. Change pLast to be the last sprite number in YOUR range.
