Detailed Description

The abstract base class of all Rigid Bodies that defines essential methods and members to be used in t2d::World<>

Constructor & Destructor Documentation

◆ WorldBody()

WorldBody::WorldBody	(	uint32_t	id,
		BodyType	bodyType )

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

◆ addLinearVel()

void WorldBody::addLinearVel ( const vec2 & vel )

inline

applies a linear velocity to this body

Parameters

vel	The linear velocity to apply to this body

◆ bodyType()

BodyType WorldBody::bodyType ( ) const

inline

Returns the bodyType of this body, see enum BodyType.

Returns: The bodyType of this body, see enum BodyType

◆ getAABB()

virtual AABB< Float > WorldBody::getAABB ( ) const

pure virtual

Returns the AABB of this body.

Returns: The AABB of this body

Implemented in BulletBody, and TileBody< TileType >.

◆ getLocalPoint()

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

inlinevirtual

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 in Body.

◆ getWorldPoint()

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

inlinevirtual

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 in Body.

◆ getWorldPos()

virtual vec2 WorldBody::getWorldPos ( )

inlinevirtual

Returns the world position of this body.

Returns: the world position of this body

Reimplemented in Body.

◆ id()

uint32_t WorldBody::id ( ) const

inline

Returns the id assigned to this body the physics world.

Returns: The id assigned to this body the physics world

◆ integrate()

virtual void WorldBody::integrate ( Float dt )

pure virtual

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

Implemented in Body, BulletBody, and TileBody< TileType >.

◆ inverseMass()

Float WorldBody::inverseMass ( ) const

inline

Returns the inverse mass of this body.

Returns: The inverse mass of this body

◆ isStatic()

bool WorldBody::isStatic ( ) const

inline

Returns if the body is static, meaning it cannot be moved by forces or other bodies.

Returns: True, if static

◆ mass()

Float WorldBody::mass ( ) const

inline

Returns the mass of this body.
