Yes.. sprite(1) need not exist before you run this script..
this is a true dynamic method to create sprites at runtime. Only the catch
is in the "puppet" property, which has to be set to true, else the sprite
won't be visible.
I too have been using this method for long and have'nt yet faced any
problems. Infact I think this is the most powerful feature that director
support, which can be used to write effective and true object oriented
programming. Unfotunately a clear explanation for this procedure is not
given in Director help.
The generic code would be somewhat like this:
-- this handler puts the sprite on the stage
on putSprite
pnSpriteNum = getChannelNum() -- get the empty channel
sprite(pnSpriteNum).puppet = TRUE
sprite(pnSpriteNum).member = psInitMember
sprite(pnSpriteNum).ink = 36
end
-- this handler gets the empty channel to place the runtime sprite
on getChannelNum
repeat with lni = 1 to 1000 -- this loop starts searching for empty
channels from 1 to 1000
if sprite(lni).member.memberNum = 0 then
return lni
end if
end repeat
alert "OUT OF CHANNELS"
end
To delete the sprite:
-- this handler is used to delete the object
-- this handler is invoked when the movie goes to next screen
on deleteObject me
gnCount = gnCount - 1
sprite(me.pnSpriteNum).member = member(0,0)
sprite(me.pnSpriteNum).scriptInstanceList = []
sprite(me.pnSpriteNum).puppet = FALSE
end
