Desynchronization in projectiles

[fringe frigate]

Does anyone have any idea why this is happening in my game? If you notice, there is a very noticeable desynchronization when spawning the projectile when it is seen on the server and when it is seen by another player. But locally it looks correct

    local p = Instance.new("Part")
    p.Size, p.Shape         = Vector3.new(0.8,0.8,0.8), Enum.PartType.Ball
    p.Material              = Enum.Material.Neon
    p.BrickColor            = BrickColor.new("Cyan")
    p.Anchored, p.Massless  = false, true
    p.CanCollide, p.CanTouch, p.CanQuery = false, false, false
    p.CFrame, p.Parent      = CFrame.new(origin), workspace

    local att = Instance.new("Attachment", p)
    local lv  = Instance.new("LinearVelocity")
    lv.Attachment0            = att
    lv.VectorVelocity         = dir * PROJECTILE_SPEED
    lv.MaxForce               = math.huge
    lv.VelocityConstraintMode = Enum.VelocityConstraintMode.Vector
    lv.RelativeTo             = Enum.ActuatorRelativeTo.World
    lv.Parent                 = p

    if owner then p:SetNetworkOwner(owner) end
    game:GetService("Debris"):AddItem(p, PROJECTILE_LIFE)
end```

This is in a serverScript

maybe try using a raycast simulated bullet instead

this is normal, and happens in all multiplayer games. it's happening here in particular because you are setting network owner immediately after creation, before it exists on the owner's computer, and because it belongs to that player, the server won't simulate it, this is offloaded to that player's computer, which will take time to replicate back to the server and then to the other players.

to fix it imo just remove the setnetworkowner

yk exploiters can teleport the bullet into the enemy if you give them network owner, make server raycast and tell all clients to hallucinate a bullet following the ray (probly just tween it from origin to hit) that way everyone will have em all smooth

Okok thanks
