Detailed Description

Physics wrapper.

The World class manages the Bullet physics engine under the hood to provide advanced collision detection and dynamics in real-time.

To have a physics enabled scene you also need to wrap your scene nodes in Object objects and to register them in the World

See also:

Object

Constructor & Destructor Documentation

World::World

(

irr::IrrlichtDevice *

d

)

ctor

Parameters:

d

Irrlicht device (needed only for the debug drawer)

Initializes the Bullet engine.

Member Function Documentation

void World::debug

(

)

perform a debug drawing of the world

Note:

This function makes use of Irrlicht video driver and must thus be called between beginScene() and endScene() calls.

void World::update

(

irr::f32

dt

)

Updates the physics world.

Note:

This function affects the position and rotation of managed (through an Object) scene nodes based on physic consideration (gravity, collision, ...)

References Object::collision().

bool World::raycast	(	const btVector3 &	org,
		btVector3 &	dst,
		btVector3 &	ort,
		btCollisionObject *	o = 0
	)

Raycasting helper function.

Note:

if you are using raycast you probably don't need this helper function anyway and ought to use Bullet directly...

Referenced by raycast().

bool World::raycast	(	const irr::core::vector3df &	org,
		irr::core::vector3df &	dst,
		irr::core::vector3df &	ort,
		btCollisionObject *	o = 0
	)

Raycasting helper function.

Note:

if you are using raycast you probably don't need this helper function anyway and ought to use Bullet directly...

References raycast().

irr::IrrlichtDevice * World::getDevice

(

)

const

Returns:

the Irrlicht device passed to the ctor

Referenced by Camera::event().

btDiscreteDynamicsWorld * World::getDynamicsWorld

(

)

const

Returns:

pointer to the internal (Bullet) world

Note:

Using this function is not recommended unless you know what you are doing. It is part of the API only for other physics-related class to use (e.g Object, Camera and Character)

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