Part X: Dynamic Animation
Creating reactor Objects
In addition to collections, reactor also includes several default objects that react with the scene in unique
defined ways. These objects can be created using the Animation ➪ reactor ➪ Create Object menu commands
or by clicking its icon in the reactor toolbar and dragging in one of the viewports.
The default objects include Spring, Plane, Linear Dashpot, Angular Dashpot, Motor, Wind, Toy Car,
Fracture, and Water, as listed in Table 43.3.
TABLE 43.3
reactor Objects
Toolbar Button Name Description
Spring Acts to bring connected child and parent objects closer together
Plane Adds a solid plane object to the scene

Linear Dashpot Acts to limit linear motion between connected child and parent objects

Angular Dashpot Acts to limit angular motion between connected child and parent objects

Motor Used to add angular force to the scene

Wind Used to add linear force to the scene

Toy Car Simulates a simple car with rotating wheels and linear motion

Fracture Identifies objects that can be broken into pieces

Water Adds water to the scene that conforms to concave surface

The gizmos for these objects, like the collection gizmos, appear red when first created for most of these
objects and then turn white when selected, and blue when connected, to a geometry object. Figure 43.6
shows the gizmo icons for each of these reactor objects.
Most of these objects need to be associated with an object to be included in reactor. For example, the Toy
Car reactor object must be connected to a geometry object for its chassis and up to four geometry objects
for its wheels. This is done by clicking on the respective buttons in the Properties rollout and selecting the
geometry object in the viewport. For example, you can connect a Spring object to both a Child and a Parent
object. Other reactor objects, like the Plane and Wind objects, do not need to be connected to an object
to work.
