They always refer to the Object you selected first in the group. These
commands are of great help when it comes to tidying up your Interfaces.
Experiment a bit with those to get the hang. And always remember that you have
the Undo command to roll back changes.
3.2.8. Configuring Object’s behaviour
Now, let’s glance at one of the most powerful feature of the Lemur’s
objects : their configurable behaviour. Select the MultiBall object with the mouse,
and look at the Behavior panel. The following display will appear:
The Physics menu has three modes defining the behaviour of the
balls. When Physics is set to None, the ball moves immediately to the position of
your finger and stays there. It also follows your finger around as you move it on the
touch screen, and immediately stops when you lift up your finger.
Make sure the Physics menu is set to Interpolate, which should be the
default setting.
Touch the Lemur screen somewhere in the MultiBall, but not on top of a
ball. The ball will not move to your finger immediately but according to the setting
of the Attraction property. Let’s modify Attraction to make the ball react more
slowly. Enter a value of 0.1.
Experiment again with the Ball’s reaction. It should follow your finger
slowly.
Now let’s try the last behavior mode. Choose Mass-Spring from
the Physics menu.
Change the Attraction value to 1.0 and the Friction to 0.2.
