Physics abstract class
|
||||
|
||||
A physics object is a tool to manipulate the position and orientation of
|
||||
an entity. The physics object is a container for idClipModels used for
|
||||
collision detection. The physics deals with moving these collision models
|
||||
through the world according to the laws of physics or other rules.
|
||||
|
||||
The mass of a clip model is the volume of the clip model times the density.
|
||||
An arbitrary mass can however be set for specific clip models or the
|
||||
whole physics object. The contents of a clip model is a set of bit flags
|
||||
that define the contents. The clip mask defines the contents a clip model
|
||||
collides with.
|
||||
|
||||
The linear velocity of a physics object is a vector that defines the
|
||||
translation of the center of mass in units per second. The angular velocity
|
||||
of a physics object is a vector that passes through the center of mass. The
|
||||
direction of this vector defines the axis of rotation and the magnitude
|
||||
defines the rate of rotation about the axis in radians per second.
|
||||
The gravity is the change in velocity per second due to gravitational force.
|
||||
|
||||
Entities update their visual position and orientation from the physics
|
||||
using GetOrigin() and GetAxis(). Direct origin and axis changes of
|
||||
entities should go through the physics. In other words the physics origin
|
||||
and axis are updated first and the entity updates it's visual position
|
||||
from the physics.
