Thx <img src="smileys/smiley16.gif" border="0" align="middle" />
But what I don't know is : how can I know when it is consistant to break on objet or another?
For example, in real life, if you throw a fragile object on a stone wall at high speed, this object will be broken and the wall won't be. But if you throw, on the same wall at the same speed, let's say... a canonball, the wall will be broken ! (eventually)
And if you throw the fragile object at low speed, it won't be broken.
Know what I mean? I'd like to understand and apply this consistency with C2.
