Constructor & Destructor Documentation

Physics() [1/3]

sdf::v9::Physics::Physics

(

)

Default constructor.

Physics() [2/3]

sdf::v9::Physics::Physics

(

const Physics &

_physics

)

Copy constructor.

Parameters

[in]

_physics

Physics to copy.

Physics() [3/3]

sdf::v9::Physics::Physics ( Physics &&  _physics )

noexcept

Move constructor.

Parameters

[in]

_physics

Physics to move.

~Physics()

sdf::v9::Physics::~Physics

(

)

Destructor.

Member Function Documentation

Element()

sdf::ElementPtr sdf::v9::Physics::Element

(

)

const

Get a pointer to the SDF element that was used during load.

Returns

SDF element pointer. The value will be nullptr if Load has not been called.

EngineType()

std::string sdf::v9::Physics::EngineType

(

)

const

Get the physics profile dynamics engine type.

Current options are ode, bullet, simbody and dart. Defaults to ode if left unspecified.

Returns

The type of dynamics engine.

IsDefault()

bool sdf::v9::Physics::IsDefault

(

)

const

Get whether this physics profile is marked as default.

If true, this physics profile is set as the default physics profile for the World. If multiple default physics elements exist, the first physics profile marked as default is chosen. If no default physics element exists, the first physics element is chosen.

Returns

True if this profile is the default.

Load()

Errors sdf::v9::Physics::Load

(

ElementPtr

_sdf

)

Load the physics based on an element pointer.

This is not the usual entry point. Typical usage of the SDF DOM is through the Root object.

Parameters

[in]

_sdf

The SDF Element pointer

Returns

Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

MaxStepSize()

double sdf::v9::Physics::MaxStepSize

(

)

const

Get the max step size in seconds.

The Maximum time step size at which every system in simulation can interact with the states of the world.

Returns

The max step size in seconds.

Name()

std::string sdf::v9::Physics::Name

(

)

const

Get the name of this set of physics parameters.

Returns

Name of the physics profile.

operator=() [1/2]

Physics& sdf::v9::Physics::operator=

(

const Physics &

_physics

)

Copy assignment operator.

Parameters

[in]

_physics

Physics to copy.

Returns

Reference to this.

operator=() [2/2]

Physics& sdf::v9::Physics::operator=

(

Physics &&

_physics

)

Move assignment operator.

Parameters

[in]

_physics

Physics to move.

Returns

Reference to this.

RealTimeFactor()

double sdf::v9::Physics::RealTimeFactor

(

)

const

Get the target real time factor.

Target simulation speedup factor, defined by ratio of simulation time to real-time.

Returns

The target real time factor.

SetDefault()

void sdf::v9::Physics::SetDefault

(

const bool

_default

)

const

Set whether this physics profile is the default.

Parameters

[in]

_default

True to make this profile default.

SetEngineType()

void sdf::v9::Physics::SetEngineType

(

const std::string &

_type

)

Set the physics profile dynamics engine type.

Parameters

[in]

_type

The type of dynamics engine.

SetMaxStepSize()

void sdf::v9::Physics::SetMaxStepSize

(

const double

_step

)

Set the max step size in seconds.

Parameters

[in]

_step

The max step size in seconds.

SetName()

void sdf::v9::Physics::SetName

(

const std::string &

_name

)

const

Set the name of this set of physics parameters.

Parameters

[in]

_name

Name of the physics profile.

SetRealTimeFactor()

void sdf::v9::Physics::SetRealTimeFactor

(

const double

_factor

)

Set the target realtime factor.

Parameters

[in]

_factor

The target real time factor.
