Detailed Description

A networkable object that exists in the 3D world.

The SceneObject class provides the foundation for 3D objects in the Engine. It exposes the functionality for:

Position, rotation and scale within the world.
Working with a scene graph (in the Zone and Portal sections), allowing efficient and robust rendering of the game scene.
Various helper functions, including functions to get bounding information and momentum/velocity.
Mounting one SceneObject to another.
An interface for collision detection, as well as ray casting.
Lighting. SceneObjects can register lights both at lightmap generation time, and dynamic lights at runtime (for special effects, such as from flame or a projectile, or from an explosion).

You do not typically work with SceneObjects themselves. The SceneObject provides a reference within the game world (the scene), but does not render to the client on its own. The same is true of collision detection beyond that of the bounding box. Instead you use one of the many classes that derrive from SceneObject, such as TSStatic.

Difference Between setHidden() and isRenderEnabled

When it comes time to decide if a SceneObject should render or not, there are two methods that can stop the SceneObject from rendering at all. You need to be aware of the differences between these two methods as they impact how the SceneObject is networked from the server to the client.

The first method of manually controlling if a SceneObject is rendered is through its SceneObject::isRenderEnabled property. When set to false the SceneObject is considered invisible but still present within the scene. This means it still takes part in collisions and continues to be networked.

The second method is using the setHidden() method. This will actually remove a SceneObject from the scene and it will no longer be networked from the server to the cleint. Any client-side ghost of the object will be deleted as the server no longer considers the object to be in scope.

Member Function Documentation

Point3F SceneObject::getEulerRotation ( )

Get Euler rotation of this object.

Returns:: the orientation of the object in the form of rotations around the X, Y and Z axes in degrees.

VectorF SceneObject::getForwardVector ( )

Get the direction this object is facing.

Returns:: a vector indicating the direction this object is facing.

Note:: This is the object's y axis.

TransformF SceneObject::getInverseTransform ( )

Get the object's inverse transform.

Returns:: the inverse transform of the object

int SceneObject::getMountedObject ( int slot )

Get the object mounted at a particular slot.

Parameters:

slot

mount slot index to query

Returns:: ID of the object mounted in the slot, or 0 if no object.

int SceneObject::getMountedObjectCount ( )

Get the number of objects mounted to us.

Returns:: the number of mounted objects.

int SceneObject::getMountedObjectNode ( int slot )

Get the mount node index of the object mounted at our given slot.

Parameters:

slot

mount slot index to query

Returns:: index of the mount node used by the object mounted in this slot.

int SceneObject::getMountNodeObject ( int node )

Get the object mounted at our given node index.

Parameters:

node

mount node index to query

Returns:: ID of the first object mounted at the node, or 0 if none found.

Box3F SceneObject::getObjectBox ( )

Get the object's bounding box (relative to the object's origin).

Returns:: six fields, two Point3Fs, containing the min and max points of the objectbox.

int SceneObject::getObjectMount ( )

Get the object we are mounted to.

Returns:: the SimObjectID of the object we're mounted to, or 0 if not mounted.

Member Data Documentation

bool SceneObject::isRenderEnabled

Controls client-side rendering of the object.

See also:: isRenderable()

bool SceneObject::isSelectionEnabled

Determines if the object may be selected from wihin the Tools.

See also:: isSelectable()

int SceneObject::mountNode

Node we are mounted to.

pid SceneObject::mountPID

PersistentID of object we are mounted to.

Unlike the SimObjectID that is determined at run time, the PersistentID of an object is saved with the level/mission and may be used to form a link between objects.

MatrixPosition SceneObject::mountPos

Position we are mounted at ( object space of our mount object ).

MatrixRotation SceneObject::mountRot

Rotation we are mounted at ( object space of our mount object ).

MatrixPosition SceneObject::position

Object world position.

MatrixRotation SceneObject::rotation

Object world orientation.

Point3F SceneObject::scale
