Hi,
I can not spawn construction_cone:
source /home/simulations/ros2_sims_ws/install/setup.bash
ros2 run gazebo_ros spawn_entity.py -entity construction_cone -database construction_cone
After running this command I get:
user:~$ source /home/simulations/ros2_sims_ws/install/setup.bash
user:~$ ros2 run gazebo_ros spawn_entity.py -entity construction_cone -database construction_cone
[INFO] [1704193034.819832597] [spawn_entity]: Spawn Entity started

I tried this with -timeout 180, but same issue.
I tried spawning coke_can, same issue.
I tried modifying turtlebot3_tc_world.launch.py in
/home/simulations/ros2_sims_ws/src/t3_humble_simulation_pkgs/turtlebot3/turtl
ebot3_simulations/turtlebot3_gazebo/launch
with adding -s libgazebo_ros_factory.so when starting the simulation:
ExecuteProcess(
cmd=['gazebo', '--verbose', world, '-s', 'libgazebo_ros_init.so', '-s', 'libgazebo_ros_factory.so'],
output='screen')
and restarting the simulation.
(Probably it was not a good idea because simulation did not start then something put the original launch file back so the simulation is ok now but not the spawning of the construction_cone)
Can someone help me with the spawning issue?
Thank you in advance
Péter
