Detailed Description

A plugin that blinks light and visual elements in a model.

In addition to the features of the base plugin, FlashLightPlugin, this plugin accesses a <visual> element to make it blink.

The <light> and <visual> element to control must have the identical name and specified by <light_id>, including the name of the link, which they are attached on, and their name separated by a slash "/".

Other parameters are inherited from the base plugin, FlashLightPlugin.

Example:

/// <model name='light_model'>
///   ...
///   <link name='light_source'>
///     ...
///     <light name='lamp' type='point'>
///       ...
///     </light>
///     <visual name='lamp'>
///       ...
///     </visual>
///   </link>
///   ...
///   <plugin name='light_control' filename='libLedPlugin.so'>
///     <light>
///       <id>light_source/lamp</id>
///       <block>
///         <duration>1</duration>
///         <interval>1</interval>
///         <color>1 0.5 0.5</color>
///       </block>
///       <enable>true</enable>
///     </light>
///   </plugin>
/// </model>

◆ 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]	_filename	the path to the shared library.
[in]	_name	short name of the plugin

Returns: Shared Pointer to this class type

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

		const physics::ModelPtr &	_model,
		const common::Time &	_currentTime
	)

protectedvirtual

Create an object of setting.

NOTE: This function is internally called in Load() of the base class. If a child class of FlashLightPlugin has also an inherited class of FlashLightSetting, this function must be overridden so that dataPtr deals with objects of the appropriate setting class.

Parameters

[in]	_sdf	SDF data for the setting.
[in]	_model	The Model pointer holding the light to control.
[in]	_currentTime	The current time point.

Returns: A pointer to the newly created setting object.

Reimplemented from FlashLightPlugin.

◆ GetFilename()

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.

inlineinherited

Returns the type of the plugin.

Returns: type of the plugin

References PluginT< T >::type.

◆ Init()

◆ InitSettingBySpecificData()

virtual void InitSettingBySpecificData ( std::shared_ptr< FlashLightSetting > & _setting )

protectedvirtual

Initialize the additional part of an object of setting.

NOTE: This function is internally called in Load() of the base class. If a child class of FlashLightPlugin has also an inherited class of FlashLightSetting, this function must be overridden so that the object can be initialized with necessary data. Also, the overridden function must call the original function in it.
