Hi,
I'm using the callback class like class X{ callback(){} X(){ros::publisher sub1 = n.subscribe(&callback); callback();} run()};
but can you do from this callback method: callback(){ ros::publisher sub2 = n.subscribe(&callback2); callback2():}. I couldn't find about this.
I hope the question is clear. Thanks.
Your code is a bit fuzzy and won't compile, but in principle yes, you can do all of that.
A callback is just a method that you can call manually if you need to. You can also create subscriptions whenever you want.
There is only one flaw in your code: The subscribers/publishers are declared locally, so once the function is done, they will be destroyed.
