4.1.9. RingArea
The RingArea tracks your finger inside a circular space. It reports the X
and Y coordinates of a ball that can be programmed to have a variable degree of
attraction toward a central point. You can specify the location of the attraction point
within the circular space.
Variables
x The horizontal position of the ball.
y The vertical position of the ball.
Dimensions
Default 128 x 128 pixels
Minimum 128 x 128 pixels
General Properties
Name The name of the RingArea Object that’s also used as its
address.
Label If checked, the Object’s name is displayed above the circular
space.
Color Drag the color bar to change the background color of the circular space. The ball
and attraction point are lighter variants of this color.
Behavior Properties
Capture If Capture is checked, an Object will only react to cursors that were created
inside its area. Even if the cursor later leaves the Object for another position, it
will remain in control of the original Object, until it is destroyed eventually. When
Capture is off, the old school way from previous versions is restored, meaning an
Object will react to whatever cursor is present at any moment in its area.
Attraction A value from 0-1 representing the speed of the ball from its attraction point to
your finger when you touch the Object, and from your finger to the attraction
point when you release your finger.
Friction A value from 0-1 representing the stickiness of the movement to either your
finger or the attraction point. Lower values of friction make the ball overshoot
the attraction point when it approaches, causing bouncing and/or oscillation.
