If it is meant to read "Sentinel is sweeping in quick", I cannot see that "sweeping" could be anything but a present participle.
It's obviously one of the constraints of an asynchronous medium that you cannot get immediate feedback. If you ask for clarification, half the time you get no response.
If adel87 cannot make sense of my answer and wants clarification, s/he knows where I am.
"Sentinels are essentially hovering drones armed with energy weapons called Sentinel Beams which is a Laser-based directed energy weapon The weapon is particularly effective against small flood outbreaks and Energy Shields which are an important piece of technology that protect the users from harm, The drones are equipped with energy weapons which they fire in a sweeping motion. (like a window wiper)"
To answer your question, the verb sweep means 'to move steadily and strongly or swiftly', and it's usually followed by the word along, down, by, in, into, etc.
Dear Sir and/or Madam
In the sentence Sentinel's sweeping in quick, I can't find sweeping as noun (in my dictionary). What is its function and meaning?
Having said that, though, I've noticed that often times the defensive tone of your posts serve more to scare posters off than to invite them to communicate with you in a positive way. I trust you know by now, being an academic yourself--at least that's what is says in your Bio--that in academia, it's not what you say per se that sways your audience, but more so how you say it; moreover, in academia, it's the author's ideas that are challenged, never the author. In challenging the author, not only do we distract the audience from the issue under discussion, but also lose the opportunity to learn and understand what that person has to teach us.
Having been an on-line teacher for almost 10 years now, my learned advice to you is this. Don't take posts personally; start looking at them from an academic point of view. After all, this is the Ask a Teacher Forum. Posters are expecting to hear learned advice from a educator, one that has the patience and understanding of a professional. Be that.
