11. You??™re probably noticing that the pieces of GlassWindow break apart, but sort of
drift off and do not really have any weight or motion of their own. In the HardFX
controls for the GlassWindow, choose ??“9.8 from the Gravity drop-down. Click
Calculate, and you??™ll see the object start to fall before and after the collision. That??™s
better, but you want the gravity to not apply until the collision happens.
12. Click the Collision tab of the
HardFX controls and check Start
by Collision, as shown in Figure
14.28. Then click Calculate again.
GlassWindow sits still until the
collision effector strikes it, and
then its pieces expand and begin
to drop.
From this point on, it??™s a matter
of tweaking the settings and
observing the results until the
animation looks the way you
want it to look. None of the
remaining steps in this exercise
are essential or strictly ???correct.???
Try them all to acquaint yourself
with the effects of the controls
they describe, and decide for
yourself if you want to keep the
suggested settings, apply higher
or lower values, or discard the
adjustments altogether.
