I used BasePart:SetNetworkOwner(nil) to make the server the network owner of a basepart, in this case a blue cylinder, and move it via the server.
The issue here is that the change in position from LinearVelocity does not replicate to client, it’s interactions with other physics parts behave normally, even though it doesn’t appear to move at all from the clients perspective.
This happens 100% of the time.
Video proof:
Roblox place where the bug is observable (The cylinder moves along with the player)
If I am missing any information please let me know, thank you.
1.- Make a part with a LinearVelocity and attachmentDescendants.
2.- Parent the part to replicatedStorage.
3.-Place the following script in ServerScriptService
local PlayerInfo = require(game.ReplicatedStorage.Entity.PlayerEntity)
function get_available_character()
local char = game.ReplicatedStorage.AvailablePlayers:FindFirstChildWhichIsA("Part")
char.Parent = workspace
return char
end
function on_player_join(Player)
Player.CharacterAdded:Wait()
local part = PlayerInfo.new(Player , get_available_character())
local function update_char_move_direction(dir)
part:change_move_direction(Player.Character.Humanoid.MoveDirection)
end
Player.Character.Humanoid:GetPropertyChangedSignal("MoveDirection"):Connect(update_char_move_direction)
part.Model:SetNetworkOwner(nil)
end
game.Players.PlayerAdded:Connect(on_player_join)
4.- Place the following script in ReplicatedStorage
local Entity = {}
Entity.__index = Entity
function Entity.new(model : Model)
local self = setmetatable({} , Entity)
self.Model = model
self.PrimaryPart = model.PrimaryPart
self.speed = 30
return self
end
function Entity:change_move_direction(direction : Vector3)
if self.enabled then
self.PrimaryPart.LinearVelocity.VectorVelocity = direction * self.speed
else
self.PrimaryPart.LinearVelocity.VectorVelocity = Vector3.zero
end
end
return Entity
5.-Add this script as a Child of the Entity module in replicatedStorage and run the game
local Entity = require(script.Parent)
local CharacterController = {}
CharacterController.__index = CharacterController
setmetatable(CharacterController , Entity)
function CharacterController.new(player : Player , character : Model)
local self = setmetatable(Entity.new(character) , CharacterController)
self.Player = player
self.PlayerCharacter = self:get_default_character()
self.Grabbing = nil
self.enabled = false
self.immune = false
return self
end
function CharacterController:get_default_character()
if not self.Player.Character then
self.Player.CharacterAdded:Wait()
end
return self.Player.Character
end
return CharacterController
This version of the ServerScriptService script fixes the bug, the only difference is that the model’s parent is set outside of the class constructor, which might be what causes the replication issue.
local PlayerInfo = require(game.ReplicatedStorage.Modules.Entity.PlayerEntity)
function get_available_character()
local char = game.ReplicatedStorage.AvailablePlayers:FindFirstChildWhichIsA("Model")
return char
end
function on_player_join(Player)
local CharController = PlayerInfo.new(Player , get_available_character())
local function update_char_move_direction(dir)
CharController:change_move_direction(CharController.PlayerCharacter.Humanoid.MoveDirection)
end
CharController.PlayerCharacter.Humanoid:GetPropertyChangedSignal("MoveDirection"):Connect(update_char_move_direction)
CharController.enabled = true
CharController.Model.Parent = workspace
CharController.Model.PrimaryPart:SetNetworkOwner(nil)
game.ReplicatedStorage.Remote.LinkCamera:InvokeClient(Player , CharController.Model)
end
game.Players.PlayerAdded:Connect(on_player_join)
I tried these reproduction steps and didn’t see the problem. I also attempted to make a more simplified reproduction with this: LinearVelocityNotReplicating.rbxl (55.3 KB)
Are you still having this issue with the steps that you provided? If so, would you mind taking a look at my reproduction file to see if I’m missing some core element that is present for you. Thanks.
