How do I make players stay on spining platforms? ( answered )

Well this was fun (and amusing) to work on, and it may be a little cheaty but it works!

Here ya go:

local Spin_Part =script.Parent--The part
local Spin_Pos =Spin_Part.Position
local Can =true

local function Rotate(State,Hit_Model)
    while Hit_Model.Humanoid.Jump ==false do--You jump (hold jump) to get off. A bit jumpy but it works, so...
        wait()
        Hit_Model:SetPrimaryPartCFrame(Spin_Part.CFrame)--RoTaTe!
    end
    Hit_Model.PrimaryPart =Hit_Model.HumanoidRootPart
    Hit_Model.RoPart:Destroy()
    wait(0.2)--Attempt #2 to stop "floating"
    Can =true
end

Spin_Part.Touched:connect(function(hit)
    if Can ==true and hit.Parent:IsA("Model")and hit.Parent:FindFirstChild("HumanoidRootPart")and hit.Parent:FindFirstChild("Humanoid")and not hit.Parent:FindFirstChild("RoPart")then
        Can =false
        local RotatePart =Instance.new("Part")
        RotatePart.Name ="RoPart"
        RotatePart.Size =Vector3.new(0,0,0)
        RotatePart.Transparency =1
        RotatePart.Anchored =true
        RotatePart.CanCollide =false
        RotatePart.Locked =true
        RotatePart.CFrame =Spin_Part.CFrame
        RotatePart.Parent =hit.Parent
        hit.Parent.PrimaryPart =RotatePart
        repeat wait()until hit.Parent.Humanoid.FloorMaterial ~=nil--Attempt #1 to stop "floating"
        Rotate(true,hit.Parent)
    end
end)

while true do--Your rotate script. Doesn't need to be here, it just is.
    wait()
    Spin_Part.CFrame =Spin_Part.CFrame*CFrame.fromEulerAnglesXYZ(0,0.05,0)
end

Just put this script alone into your part, and it'll take care of the rest. No editing is needed for part positions, It will adapt to the part you put it in!

I'm not sure if it'll work with more then one player, but it will work with anything containing a part named "HumanoidRootPart" and a Humanoid! (inside a Model)

So you can rotate custom made boxes and stuff.

Enjoy!
