virtual void se_core::Physics::affect ( PhysicsComponent & physics ) const [pure virtual, inherited]

State changes to actor as a result of its position should happen inside affect.
These can include health reductions as a result of standing on a firepit, etc. Changes that happen because of moving into a new terrain type should be handled by terrainMode switcher, though.

virtual void se_core::Physics::calcNext ( const PhysicsComponent & physics,

const Pos & pos,

Pos & nextPos,

const Move & move,

Move & nextMove

) const [pure virtual, inherited]

Calculate the next position of the actor.
The pos and nextPos parameter values will usually be the ones returned by actor.pos() and actor.nextPos(). But they are explicit parameters to enable movement prediction.
No state changes other than those that applies to nextPos should happen in calcNext, because the results of this method should be reversible on collision, and be usable for prediction.
It is the responsibility of this method to check for collisions with static terrain.

Parameters:

physics the physics of composite that is moved

pos the position of the actor is at the beginning of this simulation step

nextPos output var - where the actor should be the beginning of the next simulation step

move work vars for movement, as they where at the beginning if this simulation step

nextMove output var - values are the same as move when the method is first called, but changes will be passed on to the next simulation step

int se_core::Object::hash ( int type,

const char * name

) [static, inherited]

Calculate hash (object id) given object type and name.

Definition at line 42 of file Object.cpp.

int se_core::Object::id ( ) const [inline, inherited]

Get the Object id of the object.
Each instance of Object has a unique Object id assigned to it during construction. The id_ is a hash of the name. And will be the same every time the game is run.
Sometimes two different names can give the same hash, and id. When this occurs the name of the object must be changed.

Returns:
The unique Object instance id.

int se_core::Object::type ( ) const [inline, inherited]

Get the type of the Object (got_ACTION, got_THING, etc).
Classes subclassing game objects should have a type enumerated in the enum ObjectType. The subclass is itself responsible for reporting the type during construction, and a whole subclass hierarchy may share the same type (like Action and its subclasses, Script and its subclasses, etc).

Returns:
The type of the game object.
