The following section contains instructions on how to compile this plugin. GZ_REGISTER_SYSTEM_PLUGIN and GZ_REGISTER_VISUAL_PLUGIN. GZ_REGISTER_MODEL_PLUGIN, GZ_REGISTER_SENSOR_PLUGIN, There are matching register macros for each plugin type: The only parameter to this macro is the name of the plugin class.
#Tutorial 6 physics 101 simulator
GZ_REGISTER_WORLD_PLUGIN(WorldPluginTutorial)įinally, the plugin must be registered with the simulator using the The only other mandatory function is Load which receives an SDF element thatĬontains the elements and attributes specified in loaded SDF file. public: void Load(physics::WorldPtr _world, sdf::ElementPtr _sdf) class WorldPluginTutorial : public WorldPluginĮach plugin must inherit from a plugin type, which in this case is the WorldPlugin class. Or gazebo/sensors/sensors.hh as those should be included on a case by case basis.Īll plugins must be in the gazebo namespace. It doesn't include gazebo/physics/physics.hh, gazebo/rendering/rendering.hh,
#Tutorial 6 physics 101 code
Code Explained #include įile includes a core set of basic gazebo functions. The above code is also located in the Gazebo sources:Įxamples/plugins/hello_world/hello_,Īlong with an appropriate CMakeLists.txt file. GZ_REGISTER_WORLD_PLUGIN(WorldPluginTutorial) Public: void Load(physics::WorldPtr _world, sdf::ElementPtr _sdf) Public: WorldPluginTutorial() : WorldPlugin() cc file for the new plugin: $ mkdir ~/gazebo_plugin_tutorialĬopy the following into hello_: #include Ĭlass WorldPluginTutorial : public WorldPlugin If you have a release other than gazebo6, replace 6 with whatever version number you have. If you installed Gazebo from source, you can ignore this step. Hello WorldPlugin!Ī bare bones world plugin contains a class with a few member functions.įirst, if you installed Gazebo from debians, make sure you've installed the Gazebo development files. Use a Sensor plugin to acquire sensor information and control sensor properties.

Use a Model plugin to control joints, and state of a model. Use a World plugin to control world properties, such as the physics engine, ambient lighting, etc. This plugin gives the user control over the startup process.Ī plugin type should be chosen based on the desired functionality. The System plugin is specified on the command line, and loads first during a Gazebo startup. Similarly, a World plugin is attached to a world, and a Sensor plugin to a specific sensor.
