Intermediate tutorials 1 - Problem with scale

hey there,

I'm trying to run the intermediate tutorial 1 and i'm having problems with the scale attribute of entities (very basic indeed). The entities don't seem to rescale themselves. At this point when I run the application I have one robot(ninja) and 3 VERY big knots. too big. I ran this tutorial under C++ Ogre and I know something is wrong. Here's my code, but I pretty much copy and pasted it from wiki. Is there something that changed or something that I didn't understand ?

Thanks!

Basically it all boils down to this : Is there any reason the following call might not be executed properly ??

knotNode.scale = (0.1, 0.1, 0.1)

knotNode.scale = (0.1, 0.1, 0.1)

OK, after some more toying around I found out the real call is knotNode.setScale(0.1,0.1,0.1)

I thought it was supposed to work just with .scale ?
