I will try and pull an “idea” from that vague jumble of words.

Do you mean Ballista?

https://en.wikipedia.org/wiki/Ballista

The ballista (Latin, from Greek βαλλίστρα ballistra^[2] and that from βάλλω ballō, “throw”),^[3] plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched a large projectile at a distant target.

First of all, you cant just add mods into an unmodded server, you will have to go to a modded server to “Add in catapults”… Thats not something you can just “add”.

Which leaves Ballista, but you didnt explain how the projectile should work in any way shape or form, so, no I cant add something if you dont explain how the projectile should work, but from your already amazing idea to just “Add in catapults” I very much doubt you understand what is possible and what isnt possible and you will come up with something that will somehow try and magically make multiple plugins work in unison.

As for your cannon ignorance.
