Previously, replication was smooth and perfectly consistent amongst clients, for things like ragdoll, and other forms of knockback our game utilises - after this change, if a user is hit, on his client, it will remain smooth and as intended, but on the perspective of other individuals,
The character is not moving smoothly, but snapping and teleporting, most of the time, lingering before starting movement, and then snapping very fast, this video shows before and after : https://www.youtube.com/watch?v=rExlverhDrM triggering this to happen is very easy - The Strongest Battlegrounds | Play on Roblox joining tsb, and using any forward dash (Q key) up close to a separate player, or selecting ‘Hero Hunter’ from the characters tab and using the third move, hunter’s grasp, fourth move, lethal whirlwind or bald hero and using uppercut will all showcase the same results
Expected behavior
All that is required would be a simple toggle to revert to legacy physics, as we have never ever had issues with it, and i assume many other games also haven’t, for such a huge change like physics, we believe it is crucial, especially as individuals may like it in some places, but it might have minor issues in others, and whilst they wait for it to be fixed, legacy replication and physics would be perfect to have.
The repo steps in The Strongest Battlegrounds are quite complex to follow.
To help us investigate this faster, could you provide a minimal reproduction file (.rbxl) that reproduce the snapping/teleporting issue? A isolated environment with just the core physics/replication setup would be much more effective for debugging.
A simple two player test and typing in the chat is enough to trigger it -
Second character is visibly moving smoothly on his screen, where as it is stuck in place temporarily before moving on other screens
We think this may be related to this change, and we’re currently rolling it back. In about an hour, fresh servers should revert back to the old behavior. Please confirm at that time whether the issue goes away!
