Detailed Description

Plugin that applies a random velocity to a linke periodically.

///    <!-- Apply a random velocity to the specified link-->
///    <!-- In this example, we move a box around. A key property of the link
///         is the frictionless surface -->
///    <plugin name="random" filename="libRandomVelocityPlugin.so">
///
///      <!-- Name of the link in this model that receives the velocity -->
///      <link>link</link>
///
///      <!-- Initial velocity that is applied to the link -->
///      <initial_velocity>0 0.5 0</initial_velocity>
///
///      <!-- Scaling factor that is used to compute a new velocity -->
///      <velocity_factor>0.5</velocity_factor>
///
///      <!-- Time, in seconds, between new velocities -->
///      <update_period>5</update_period>
///
///      <!-- Clamp the X velocity value to between -1 and 1.-->

Member Function Documentation

§ Create()

static TPtr Create ( const std::string &  _filename,
const std::string &  _name 
)
inlinestaticinherited

a class method that creates a plugin from a file name.

It locates the shared library and loads it dynamically.

Parameters
[in]_filenamethe path to the shared library.
[in]_nameshort name of the plugin
Returns
Shared Pointer to this class type

References PluginT< T >::filename, gzerr, and SingletonT< SystemPaths >::Instance().

§ GetFilename()

std::string GetFilename ( ) const
inlineinherited

Get the name of the handler.

References PluginT< T >::filename.

§ GetHandle()

std::string GetHandle ( ) const
inlineinherited

Get the short name of the handler.

References PluginT< T >::handleName.

§ GetType()

PluginType GetType ( ) const
inlineinherited

Returns the type of the plugin.

Returns
type of the plugin

References PluginT< T >::type.

§ Init()

virtual void Init ( )
inlinevirtualinherited

Override this method for custom plugin initialization behavior.

Reimplemented in BuoyancyPlugin, HarnessPlugin, FollowerPlugin, VehiclePlugin, LinearBatteryPlugin, MudPlugin, CartDemoPlugin, SphereAtlasDemoPlugin, and DiffDrivePlugin.

§ Load()

virtual void Load ( physics::ModelPtr  _model,
sdf::ElementPtr  _sdf 
)
virtual

Load function.

Called when a Plugin is first created, and after the World has been loaded. This function should not be blocking.

Parameters
[in]_modelPointer to the Model
[in]_sdfPointer to the SDF element of the plugin.

Implements ModelPlugin.

§ Reset()

virtual void Reset ( )
virtual

Override this method for custom plugin reset behavior.

Reimplemented from ModelPlugin.
