	Gets a local position thats within the local space of this body and transforms into the world space.
virtual vec2	getLocalPoint (const vec2 &worldPoint) const override
	Gets a world position thats space of this body and transforms into the local space of this body.
virtual vec2	getWorldPos () override
	Returns the world position of this body.

Constructor & Destructor Documentation

Body()

Body::Body ( uint32_t id, BodyType type )

inline

constructs a new WorldBody

Parameters

id	The id assigned by physics world
bodyType	The type of body, see enum BodyType. Does not define whether or not the body is static, see setStatic()

Member Function Documentation

addAngularVel()

void Body::addAngularVel ( const Float & vel )

inline

Applies an angular velocity to this body.

Parameters

vel	The amount of angular velocity to apply

centroid()

const vec2 & Body::centroid ( ) const

inline

Returns the centroid of this body.

Returns

The centroid of this body

com()

const vec2 & Body::com ( ) const

inline

Returns the center of mass of this body.

Returns

The center of mass of this body

getLocalPoint()

virtual vec2 Body::getLocalPoint ( const vec2 & worldPoint ) const

inlineoverridevirtual

Gets a world position thats space of this body and transforms into the local space of this body.

Parameters

worldPoint

Position in world pos

Reimplemented from WorldBody.

getWorldPoint()

virtual vec2 Body::getWorldPoint ( const vec2 & localPoint ) const

inlineoverridevirtual

Gets a local position thats within the local space of this body and transforms into the world space.

Parameters

localPoint

Position in the local space of this body

Reimplemented from WorldBody.

getWorldPos()

virtual vec2 Body::getWorldPos ( )

inlineoverridevirtual

Returns the world position of this body.

Returns

the world position of this body

Reimplemented from WorldBody.

integrate()

inlineoverridevirtual

Integerates this body, meaning the linear velocity and angular velocity will be integrated into the position and rotation of this body.

Parameters

dt	The amount to integrate by; delta time

Implements WorldBody.

Reimplemented in TileBody< TileType >.
