After a couple of tests, I kept having bullets go to a different place than the one I clicked, so I created this script where I tried a bunch of things to try and get the bullet to be accurate.
I tried both input.Position and UserInputService:GetMouseLocation(), ScreenPointToRay instead of ViewportPointToRay (I also tried changing the depth for both of those to various different numbers), and I tried subtracting the gui inset for all combinations. For the gui inset, I tested both Vector2.new(0, 36) and GuiService:GetGuiInset().
I’m pretty sure it’s not because of the way I’m moving the bullets, because I tried a couple of different methods for that as well.
It’s not because of workspace:Raycast() either, because I tried everything that I mentioned before with Ray.new() and they had the same results.
tl;dr: I tried literally every combination of everything that I could think of that related to this, and I still don’t know why my bullets are offsetted. The name of this post is what I think is happening at this point.

bullet:Destroy()

btw the offset function isn’t related, I temporarily disabled that for testing.
