I want to learn more about Event::connect disconnect

but there is no tutorial on official website

API Documentation about "event" is very short,and I can't understand http://osrf-distributions.s3.amazonaw...11event11Events.html#ab0fefed82c8ab22f67cf5a3870bcb9ef

where to find resource if I want to better/further understand gazebo::common::events ??

Because I encountered a problem as following:

I have two plugin,

one world plugin "evaluationplatform", another one is model plugin "armcontrol"

in onUpdate() of the world plugin "evaluationplatform", I use DisconnectWorldUpdateBegin(updateconnection) to Disconnect "onUpdate()" under some condition

I tested these two plugin independently, and they worked well as I want,

but, when I used them together ,things went wrong

onUpdate() of the world plugin "evaluationplatform" cannot be disconnected

and I guess the critical point is in model plugin "arm_control"

So .I want to learn more about Event::connect & disconnect to find out the problem

Thank you!!

Can you show some of your code so we can try to reproduce the problem?

Here is the API documentation for the event system.

Here is a set of example event definitions.

Basic usage:

  1. Define an event (see gazebo/common/Events.hh for examples).

  2. Create a Connection, which registers a callback to an Event. Make sure to keep the Connection alive (don't destroy it), until you are done.

  3. Trigger the event, and the callback will be run.
