Should I use the server side for tweening instead of the client side for game logic?

TweenService V2

TweenService V2 is a module that helps with efficiently replicating tweens between the server and client. It allows for the server to run the tweens as though you are running them on the server, however, the tweens only run clientside. This reduces serverside lag as it’s not tweening the object itself, or continuously replicating the property to the client. Although the tweens only run clientside, the end result of the tween will be reflected server side once the tween has finished. I decided to…

TweenService V2 is your best bet for the actual appearance.

Server logic is a tough one such as bullets through a doorway.
TweenService V2 will update the position on the server once the tween is completed to ensure that new clients see this and server logic works. It’s not ideal to have server logic rely on position when something moves. Your best bet may be chopping the movement into smaller parts so the server still doesn’t run a tween, but does more incremental updates.
