The implementation calls DoDeserialize(), that derived classes override to read their own data.
It also calls ProcessEvent() (overridden by derived classes) for any received events.
Implements GameEntityI.

This CLIENT-SIDE function is called by the client in order to get this entity drawn.
Note that it is usually called several times per frame, in order to gather the individual terms of the lighting equation: there is a call for the ambient contribution (everything that is independent of a lightsource) and for each light source there is a call for the shadows, followed by another call for adding the lightsource-dependent contribution (diffuse and specular terms etc.).
Also note that the calling code has properly set up the Cafu Material Systems global lighting parameters before calling. That is, the ambient light color, light source position (in model space), radius, diff+spec color and the eye position (in model space) are set. However, normally only those parameters that are relevant for the current Material Systems rendering action are set: In the AMBIENT rendering action, only the ambient colors are set, in the STENCILSHADOW action only the light source position may be set, and in the LIGHTING action all parameters except for the ambient light color are set.
FirstPersonView | is true when the engine has rendered the world from this entities viewpoint, e.g. because this is the local players entity. |
LodDist | is the world-space distance of the entity to the viewer, supposed to be used for level-of-detail reductions. |
Implements GameEntityI.
|
inlinevirtual |
Returns the orientation angles of the entity itself.
Used for computing the light source and eye positions in entity (model) space. TODO: Both the signature as well as the implementation of this method are temporary, and fully expected to change later.
Implements GameEntityI.

Returns the dimensions of this entity.

virtual |
This CLIENT-SIDE function is called in order to retrieve light source information about this entity.
Returns 'true' if this entity is a light source and 'DiffuseColor', 'SpecularColor', 'Position' (in world space!), 'Radius' and 'CastsShadows' have been set. Returns 'false' if this entity is no light source. (In theory, this function might also be called on server-side, from within Think().)
Implements GameEntityI.

virtual |
Returns the proper type info for this entity.
Implements GameEntityI.
Reimplemented in DeathMatch::EntInfoGenericT.
|
virtual |
This CLIENT-SIDE function is called by the client in order to advance all values of this entity that have been registered for interpolation.
Each concrete entity class determines itself which values are interpolated (e.g. the m_Origin) by calling Register() in its constructor: see Register() for details. Interpolation is used to "smooth" values in the client video frames between server updates.
Implements GameEntityI.
|
inlinevirtual |
Let the entity know that it is about to be removed from the map.
At this time, the only purpose of this method is to give the entity a chance to break cycles of IntrusivePtrT<> to itself that would otherwise prevent it from being destructed.
Implements GameEntityI.
|
virtual |
This SERVER-SIDE function is used to notify this entity that it was touched by another entity.
'Entity' is the entity that touches this one, and is usually the entity from which the call is made. Calls are only made from within other entities 'Think()' functions. (Unfortunately, this function cannot be declared as "protected": see "C++ FAQs, 2nd edition" by Cline, Lomow, Girou, pages 249f.)
|
virtual |
This SERVER-SIDE method is called whenever another entity walked into one of our trigger volumes (trigger brushes).
It is called once per frame as long as the other entity stays within our trigger volume.
Activator | The entity that walked into our trigger volume and thus caused the call of this method. |
Note that most entity classes just do nothing in their implementation of this method, usually because they never have trigger brushes anyway. Entity classes that are very likely to provide an implementation though are EntTriggerT (of course!) and the items like weapons, so they can e.g. detect being picked up. Calls to this method normally come from within the Activator->Think() method, because it are the activators themselves that detect that they entered a trigger volume (it are not the entities with the triggers that detect that something entered their volume). (Unfortunately, this function cannot be declared as "protected": see "C++ FAQs, 2nd edition" by Cline, Lomow, Girou, pages 249f.)

virtual |
This CLIENT-SIDE function is called once per frame, for each entity, after the regular rendering (calls to 'Draw()') is completed, in order to provide entities an opportunity to render the HUD, employ simple "mini-prediction", triggers sounds, register particles, do other server-independent eye-candy, and so on.
FrameTime | is the time in seconds that it took to render the last (previous) frame. |
FirstPersonView | is true when the engine has rendered the world from this entities viewpoint, e.g. because this is the local players entity. |
As it is convenient for current code (dealing with the particle system...), it is guaranteed that there is exactly one call to this function with 'FirstPersonView==true', which occurs after the appropriate calls for all other entities. This behaviour may change in the future.
Implements GameEntityI.

inline |
This SERVER-SIDE function is used for posting an event of the given type.
The event is automatically sent from the entity instance on the server to the entity instances on the clients, and causes a matching call to ProcessEvent() there. The meaning of the event type is specific to the concrete entity class. Note that events are fully predictable: they work well even in the presence of client prediction.
|
virtual |
This CLIENT-SIDE function is called to process events on the client.
Events that have been posted via PostEvent() on the server (or in client prediction) are eventually received in Deserialize(), which automatically calls this method. In the call, Deserialize() indicates the number of new events since the last call (at least one, or it wouldn't call ProcessEvent() at all). This way, each event can be processed exactly once.
TODO: Move into private section below "DoDeserialize()" ??
|
protected |
Concrete entities call this method in their constructors in order to have us automatically interpolate the value that has been specified with the Interp instance.
Interpolation occurs on the client only: it is advanced in the video frames between server updates. Each update received from the server (applied in DoDeserialize()) automatically updates the reference value for the interpolation in the next video frames.
|
virtual |
The implementation calls DoSerialize(), that derived classes override to add their own data.
Implements GameEntityI.

This SERVER-SIDE function is used to have this entity take damage.
'Entity' is the entitiy that causes the damage (i.e., who fired a shot). It is usually the entity from which the call is made. 'Amount' is the amount of damage that was caused, and is usually subtracted from this entitys health. 'ImpactDir' is the direction from which we were hit. Calls are only made from within other entities 'Think()' functions. (Unfortunately, this function cannot be declared as "protected": see "C++ FAQs, 2nd edition" by Cline, Lomow, Girou, pages 249f.)
