Detailed Description

Base class for wind.

Constructor & Destructor Documentation

Wind ( World &  _world, sdf::ElementPtr  _sdf  )

explicit

Default constructor.

Parameters

[in]	_world	Reference to the world.
[in]	_sdf	SDF element parameters for the wind.

virtual ~Wind ( )

virtual

Destructor.

Member Function Documentation

const ignition::math::Vector3d& LinearVel

(

void

)

const

Get the global wind velocity.

Returns

Linear velocity of the wind.

virtual void Load ( sdf::ElementPtr  _sdf )

virtual

Load the wind.

Parameters

[in]

_sdf

Pointer to the SDF parameters.

boost::any Param

(

const std::string &

_key

)

const

Get a wind parameter.

Parameters

[in]

_attr

String key

See Also

SetParam

Returns

The value of the parameter

bool Param	(	const std::string &	_key,
		boost::any &	_value
	)		const

Get a wind parameter with a boolean to indicate success or failure.

Parameters

[in]	_key	Key of the accessed param
[out]	_value	Value of the accessed param

Returns

True if the parameter was successfully retrieved

ignition::math::Vector3d RelativeLinearVel

(

const Entity *

_entity

)

const

Get the wind velocity at an entity location.

Parameters

[in]

_entity

Entity at which location the wind is applied.

Returns

Linear velocity of the wind.

void SetLinearVel

(

const ignition::math::Vector3d &

_vel

)

Set the global wind velocity.

Parameters

[in]

_vel

Global wind velocity.

void SetLinearVelFunc

(

std::function< ignition::math::Vector3d(const Wind *_wind, const Entity *_entity) >

_linearVelFunc

)

Setup function to compute the wind.

Parameters

[in]

_linearVelFunc

The function callback that is used to calculate the wind's velocity. The parameters to the function callback is a reference to an instance of Wind and a pointer to an entity in the scene. The function must return the new wind velocity as a vector.

bool SetParam	(	const std::string &	_key,
		const boost::any &	_value
	)

Set a parameter of the wind.

See SetParam documentation for descriptions of duplicate parameters.

Parameters

[in]	_key	String key Below is a list of _key parameter definitions: "linear_vel" (Vector3d) - wind linear velocity
[in]	_value	The value to set to

Returns

true if SetParam is successful, false if operation fails.

ignition::math::Vector3d WorldLinearVel

(

const Entity *

_entity

)

const

Get the wind velocity at an entity location in the world coordinate frame.

Parameters

[in]

_entity

Entity at which location the wind is applied.

Returns

Linear velocity of the wind.
