I've tried using the wiki and youtube, but I assume you would use CFrame/Vector3 on the player's humanoid. If someone could tell me how to lock a players position when they have clicked an object so that lock can be toggled on and off that would be great.
If you mean make somebody stuck at a certain point then here's a solution I guess.
local player = game.Players.LocalPlayer local Character = player.Character local PartPosition = game.Workspace.Part.Position local function testing(PartPosition) Character:MoveTo(game.Workspace.Part.Position) Character.Humanoid.WalkSpeed = 0 Character.Humanoid.JumpPower = 0 end testing(PartPosition)
