Dashboard control
The Dashboard has controls for which objects are affected, Strength, Falloff Type, Falloff
Rate, Influence, and Drag.
Parameters in the Inspector
Affect: A pop-up menu that limits which objects in your project are affected by the
Repel behavior. There are three options:
•
All Objects: All objects in the Canvas are affected by the Repel behavior.
•
Related Objects: The default setting. Only other objects that are within the same
layer as the repelling object are affected.
•
Specific Objects: Only objects appearing in the Affected Objects list are affected by
the Repel behavior.
•
Affected Objects: A list that appears when Specific Objects is selected in the Affect
pop-up menu. Drag objects from the Layers tab into this list to be affected by the
Repel behavior. Objects from any layer in a project can be dragged to the Affected
Objects list. To remove an object, select the object in the list and click Remove.
Strength: A slider defining the speed with which repelled objects move away from the
object. With a value of 0, repelled objects don’t move at all. The higher the value, the
faster repelled objects move.
Falloff Type: A pop-up menu that determines whether the distance defined by the
Influence parameter falls off linearly or exponentially.
•
Linear: Repulsion between objects
falls off in proportion to the object’s distance.
•
Exponential: The closer an object is within the area of influence, the stronger it’s
repelled, and the faster it moves
away from the object doing the repelling.
Falloff Rate: This value determines how quickly the force of repulsion between objects
affected by this behavior falls off. When Falloff Type is set to Exponential, object
attraction falls off with distance. When Falloff Type is set to Linear (default), the
attraction falls off uniformly. A low Falloff Rate value results in objects quickly getting
up to speed as they move away from the object of repulsion. A high Falloff Rate causes
objects to accelerate much more slowly.
Influence: A slider that defines the radius of the circle of influence, in pixels. Objects
that fall within the area of influence move
away from the object of repulsion. Objects
that are outside of the area of influence remain where they are.
Drag: A slider that can be used to reduce the distance repelled objects travel away
from the repelling object.
