Detailed Description

Base class for all physics-enabled game objects.

An Object is attached to an Irrlicht scene node and changes its position based on input from the Bullet engine.

It must have a collision shape and a mass, set in the init() method and thus this class should be considered virtual (even though it is not) unless you know what you are doing.

Constructor & Destructor Documentation

Object::Object

(

irr::scene::ISceneNode *

node

)

ctor

Parameters:

node

Scene node to manage

The scene node is usually a (animated) mesh scene node or a terrain scene node but there is no real limitation to its nature as long as a proper shape goes with it.

Member Function Documentation

btRigidBody * Object::getBody

(

)

const

Returns:

pointer to the Bullet rigid body object

Referenced by World::addObject(), Character::Character(), World::removeObject(), Character::update(), Camera::update(), and Character::~Character().

irr::scene::ISceneNode * Object::getNode

(

)

const

Returns:

pointer to the attached scene node

Referenced by Character::update().

btVector3 Object::getCenterOfMassPosition

(

)

const

Returns:

position of the center of mass

Some meshes are centered around (i.e have their origin at) their feet so we need a consistent way to get the center of a mesh.

This method actually only affects the Y component of the position vector, based on the bounding box.

Referenced by Player::update(), and Camera::update().

void Object::update

(

)

[virtual]

Handler called at the end of each frame.

The default implementation simply update the position of the attached scene node.

References World::quaternionToEuler().

Referenced by Character::update(), and Camera::update().

void Object::init	(	btCollisionShape *	shape,
		btScalar	mass
	)			[protected, virtual]

Initialize the collision object from a shape and a mass.

Parameters:

	shape	collision shape of the object
	mass	mass of the object (negative for kinematic object and null for static ones)

References World::irrToBullet().

Referenced by Box::Box(), Capsule::Capsule(), Mesh::Mesh(), SharedMesh::SharedMesh(), and Sphere::Sphere().
