Re: Manual Questions

[chikitin <cs...@gm...>]

Thanks much for the answers. Unforntunatly it seems none of the methods that
you describe for for me. 
I want pipmak as soon as leaves a specific node, show the small fram in the
middle of the page and start over the game. well, I supposed something like
this work:

img = pipmak.newimage("congratulations.jpg") // picture file is in the node
folder

onleavenode(
function

slide(img)

end
)

but this gives me an error:attemp to call global slide ( a nil value). 

thanks in advance,

cs
