So here is a script which basically says "If plr is in this group() CFrame/Vector3 to () I have the script in my ServerScriptStorage but I still can't figure out why it won't work. (I am new to scripting)
local plrs = game:GetService("Players");
plrs.PlayerAdded:Connect(function(plr)
if plr:IsInGroup(3846293) then
local character = plr.Character or plr.CharacterAdded:Wait();
local torso = character:WaitForChild("HumanoidRootPart") -- Better to use the HumanoidRootPart than the torso in my opinion.
torso.CFrame = CFrame.new() -- The CFrame is set here. Make sure to add the values for the CFrame.
end
end) -- (Credits to KingLoneCat for the Script)
