Model_only reset not supported in Gazebo Fortress

[paoloelle]

Environment

• OS Version: Ubuntu 22.04
• Gazebo Fortress
• Rendering plugin: ogre2

Description

• Expected behavior: Reset the world models to its starting position state
• Actual behavior: The world models doesn't reset to its starting position

Steps to reproduce

I'm try to run the service by using ros_gz_bridge but the behavior is the same also without it.

1. First terminal: ign gazebo arena3.sdf -v 4
2. Second terminal: ros2 run ros_gz_bridge parameter_bridge /world/arena/control@ros_gz_interfaces/srv/ControlWorld@ignition.msgs.WorldControl@ignition.msgs.Boolean
3. Third terminal: ros2 service call /world/arena/control ros_gz_interfaces/srv/ControlWorld "{world_control: {reset: {model_only: true}}}"

Output

[Wrn] [SimulationRunner.cc:1131] Model only reset is not supported.
