Bad Parameter ! box

Question

Hello,
I have a message box which pops when I run my code, but it
doesn't look like a error with my code, its a smaller warning sign
message box saying "Bad Parameter" I haven't put a alert box like
this anywhere in my code. My code is using a shockwave 3D sprite
and connect to shockwave multiuser server on local machine. What do
you think this error could be? A bug with director? or with a Xtra?
I'm using havok, and 3DPI as well.
Cheers for any replies

besides creating message boxes of your own, Diretor will spit
out errors in a message box if there is any errors in your scripts,
depending on if you are in author mode or runtime mode, When you
get an error in athouring mode, and you get an error, this means
there is a peice of code that Driector does not understand at all.
For example, lets say you wanted to move a sprite on the stage 5
pixels down the stage. The correct dot syntax to do so is like
so....
sprite(1).locV = sprite(1).locV + 5
... but lets say you made a mistake and typed this in...
sprite(1).locV = sprite.locV + 5
doing this and after you press the compile button or close
the script window, you would get an error window that looks simular
to as you calling the alert handler stating...
"Script Error: Operator expected"
sprite(1).locV = sprite.?locV + 5
In addition, you can also have errors at run time. An example
of this would be somthing like so...
lets say we still want to move this sprite 5 pixels down, but
this time you want this to happen when you call a custom handler.
Now the correct way of doing this can be something like this...
property pTimer
on beginSprite
pTimer = the milliseconds
end beginSprite
on exitFrame me
if (the millseconds - pTimer) = 1000 then
moveMe(me)
pTimer = the milliseconds
end if
go to the frame
end exitFrame
-- Note the code below is the custom handler that needs to be
inside the same script or else you will get an error at runtime
on moveMe me
sprite(me.spriteNum).locV = sprite(me.spriteNum).locV + 5
end moveMe
... now if you did not have the moveMe custom handler inside
the above script then at runtime you would get the same error
window stating this
"Script error: Handler not defined
moveMe(me)
#moveMe"
So what I am saying is, your error is a script error that
Director is spiting out because there is something wrong with your
code, and we can not help you if you do not post your script in
here.
