126 Chapter 1 Getting to Know Motion
Because different types of objects and effects require different parameters, varied sets
of controls appear in the Inspector depending on what is selected. The following table
describes the various types of controls and their usage.
Control Control type Description
Slider Dragging the slider changes the value of the
parameter. Typically, dragging to the right
increases the value and dragging to the left
decreases the value. An example of a
parameter that uses a slider is Scale.
You can Option-click to the left or right of the
slider marker to decrease or increase by a value
of 1.
Many sliders contain a disclosure triangle that
you can click to display individual
subparameters.
Value slider A special type of slider that includes the
numerical value of the parameter in the
control. Dragging the middle area (where the
number is) works just like an ordinary slider;
dragging to the right increases the value and
dragging to the left decreases the value. Some
parameters allow you to increase or decrease
the value indefinitely. Additionally, you can
click the right or left arrow to change the value
one step at a time. Option-clicking the arrows
increases or decreases by.01. You can double-
click the number itself to convert the slider into
a value field so you can type a specific number
directly into the control. An example of a
parameter that uses a value slider is Position.
Many sliders contain a disclosure triangle that
you can click to display individual
subparameters.
Note: When a value slider or value field is
active (highlighted), press Tab to move to the
next field.
Dial This control is used for values based on angles
or degrees. Rotate the dial by dragging it in a
clockwise or counter-clockwise motion. A
parameter that uses a dial is Rotation.
Value field This control allows direct entry of text to set
the value of the parameter. An example of a
parameter that uses a value field is the Text
Entry field.
Pop-up menu A menu with preset values. Click the menu and
choose the value you want. An example of a
pop-up menu is the Throw behavior’s
Increment parameter.
