gym_ignition.context.gazebo.plugin¶

class gym_ignition.context.gazebo.plugin.GazeboPlugin¶

Bases: abc.ABC

Base class of all World and Model plugins for Ignition Gazebo.

Classes that inherit from Plugin have to provide the following information:

All the properties of the plugin as dataclass fields
The private specification of the plugin (plugin name and plugin class)
Optionally: the serialized XML context

Example:

plugin = MyPlugin(my_property=42)
model = MyModel(world=my_world)

model.insert_model_plugin(*plugin.args())

args()¶

Get the arguments passed to the ScenarI/O methods used to insert plugins.

Return type: Tuple[str, str, str]
Returns: A tuple with the args required to insert the plugin.

to_xml()¶

Get the XML plugin content.

Return type: str
Returns: The XML plugin content.

static wrap_in_sdf(context)¶

Wrap the XML context inside a SDF root.

Parameters: context (str) – The XML string with the plugin’s context.
Return type: str
