So, go back to the ball object and select
the HardFX listing to access its controls. You only need to click it once for the
controls to appear on the Dynamics tab.
9. The first thing you want to do is give the ball some gravity. In the Basic tab of the
HardFX controls, set Gravity to ??“9.8. It??™s the last setting in the drop-down, and it
corresponds to the acceleration due to gravity on Earth, 9.8 meters/second 2. (The
negative value reflects the fact that gravity pulls downward, along the negative
Y-axis.)
10. Set the last frame of the animation to 400.
11. Click the Calculate button on the Object Properties panel??™s Dynamics tab.Whoa!
The ball falls and bounces down the solid object (Figure 14.6)!
Figure 14.6 With two dynamics applied, your animation starts to have interaction.
Believe it or not, that??™s all there is to it! You??™ve just created hard-body dynamics.
However, there are many more controls to play with, so save the scene and move
on to experiment a little.
You might have noticed that the ball doesn??™t quite fall down through all of the
obstacles. A few more adjustments are in order.
