Re: Attach behavior to sprite...

[Irv Kalb]

Here's my guess about your problem, and a potential fix.  The problem 
has to do with the value of "spriteNum".  When you use a behavior 
normally (attached during authoring), the special property variable 
spriteNum is automatically given the corrent value.  All you have to 
do is to declare spritenum as a property, and it will be given the 
value of the channel number of the sprite.

However, if you attach a behavior "on the fly", this assignment does 
not happen.  To fix this, you can do it in your code.  I see below 
that you are creating an instance of the cursor script by doing this:

  xCursor = (script "flaCursorScript").new(2)

However, you don't show your "new" handler in the behavior.  I'll bet 
that you can fix this problem by doing this:

property spriteNum

on new me, whichChannel
  spriteNum = whichChannel  -- assign spriteNum here
  -- anything else you want to do here
  return me
end
Then just use spriteNum in  your exitFrame handler (and you don't 
need your beginSprite handler).

Or, if you like using your spriteRef variable, you can have your new 
method just do this instead:

on new me, whichChannel
  spriteRef = whichChannel
  -- anything else you want to do here
  return me
end

Hi,

Below I have attached some simple code... The purpose with the code is to
(at runtime) be able to attach a behavior to a puppeted sprite containing a
flash member. The code works as long as I do not use the 'pSpriteRef'
variable and say instead type '2' or '3' (in the exitFrame handler in the
BEHAVIOR CODE below)... Unfortunately this will not work for me because this
behavior will be attached to more than one sprite (and the purpose of using
a behavior would be lost if I need to hardcode object references)... The
error message complains about the #hitTest which to me sounds like it does
not recognize the sprite as a flash sprite.
Anyone? Suggestions?
