如何使物体跟随玩家平滑

Question

我使用 MoveTo 跟踪位置并更改 CFrame 进行旋转，但它看起来非常锯齿。我认为问题是代码在服务器端而不是在客户端，因为我希望其他玩家能够看到跟随玩家的对象

尝试使用 weldConstrain。您可以通过代码创建它并将 2 个部分连接到它。这些零件将彼此保持相同的相对位置。这是关于该主题的 API 参考的 link：https://developer.roblox.com/en-us/api-reference/class/WeldConstraint 这是一个示例代码，在玩家加入游戏时在其头顶添加一个部件：

local Players = game:GetService('Players') -- get's the players service

local function OnPlayerAdded(player)
  local PlayerCharacter = player.Character
  -- waits until the player's character loads
  while PlayerCharacter == nil do
      wait(1)
      PlayerCharacter = player.Character
  end

  -- Get's the player's model in workspace
  local PlayerModel = workspace:WaitForChild(PlayerCharacter.Name)
  -- Get's the player's head inside it's model
  local PlayerHead = PlayerModel:WaitForChild('Head')
  -- Write the path to the part you want to follow the player, bellow
  local FollowPartOriginal = workspace:WaitForChild('Part')
  -- If you want to clone the part, so more players can be followed by it,
  -- don't delete the line below, if you want only 1 part, delete the line below.
  local FollowPart = FollowPartOriginal:Clone()
  -- set's the part position on top of the player's head, with an offset
  FollowPart.Position = PlayerHead.CFrame.p + Vector3.new(0,2,0)
  FollowPart.Parent = workspace
  -- creates a weldconstrain
  local WeldConstraint = Instance.new('WeldConstraint')
  -- connect's the weld to the player's head and the other part 
  WeldConstraint.Part0 = PlayerHead
  WeldConstraint.Part1 = FollowPart
  WeldConstraint.Parent = PlayerHead
end

Players.PlayerAdded:Connect(OnPlayerAdded)

将这段代码放在脚本中（不是本地脚本）。如果单独使用该功能，请不要忘记放置播放器参数。参数需要包含播放器Instance(ex: game.Players.PlayerName) 要更改零件位置，请使用此代码行中的偏移量：

FollowPart.Position = PlayerHead.CFrame.p + Vector3.new(write offset here)

如果你想让零件停止跟随玩家，制作脚本删除零件，或者焊接约束（玩家头部的child）
