Physics Interactor Properties

Physics interactor properties are managed through the Properties panel. You can view and modify them.

You can only create one physics interactor in an experience. To create your physics interactor, you can either use the action bar by clicking Create Physics Interactor or use the library behaviors by adding the Physics Interactor behavior to an arrow primitive.

This page discusses:

General

Active
Defines whether or not a behavior is active during a playing session.
Notes:
  • An inactive behavior or script is not executed during a playing session.
  • The behavior's activity depends on the actor's activity. If its associated actors are inactive, the behavior is also inactive.

Parameters

Force Factor
Adjusts the forces applied to the rigid body object.
Mass Dependent
Applies a force proportional to the mass of the selected rigid body object.
Show Interactor
Displays the arrow during the interaction.
Manipulation Plane
Defines the projection plane used to move or to apply forces on the 3D actor.

Four options are available:

  • Plane X/Y: Defines the plane that is used to pan a 3D actor on a planar horizontal surface.
  • Camera Z/UP: Defines the plane that is used to lift a 3D actor in the current camera viewpoint.
  • Automatic-Normal: Automatically selects the best plane based on the picking point.
  • Automatic-View: Automatically selects the best plane based on the camera viewpoint.
Application Point
Defines the point where the force must be applied.

Two points are available:

  • Picking Point: Applies forces when you select a point.
  • Center of inertia: Applies forces to the center of inertia.
Interactor Type
Defines the type of interaction with the object.

Three types are available:

  • Grab: Follows the mouse in the projection plane. The 3D actor moves when it collides with other objects.
  • Drag: Applies a continuous force to the picked object.
  • Push: Applies a punctual force to the rigid body to move forward.
  • Pull: Applies a punctual force to the rigid body.
