How to do a Character Walking Cutscene??

I was wondering if someone could help me on a Player walking Cut scene. Basically what the does is make your character walk to a place, uncontrollable, by uncontrollable I mean the player cannot walk. If you'd like to see more in depth of what I mean, check out Pokemon Brick Bronze, when you walk into a door.

I've tried doing this:

local humanoid = .Parent.Humanoid

while wait() do
    humanoid:MoveTo(workspace.Part.Position)
end

But the player can still walk, with a little glitch. I have also checked the wiki

(I am also a little familiar with Lua, just dont know how to do this)
