How do i Disable Keyboard Input In My Script??

Problem

You want to disable the character's movement abilities until it's done

Solution

A humanoid has the option in the properties bar to change movement and such. Add this to the script:

humanoid.Walkspeed = 0
humanoid.JumpPower = 0
wait(1)

and this after:

wait(1) 
humanoid.Walkspeed = 16
humanoid.JumpPower = 50

This'll wait for one second before TPing the player and it'll freeze the player for 2 seconds.

Final Script

local Hit = game.Workspace.Model.Hit
local L1 = game.Workspace.Model.L1
local End = game.Workspace.Model.End  

function onTouched(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
	        local character = hit.Parent
		local humanoid = character:WaitForChild("Humanoid")
		humanoid.Walkspeed = 0
		humanoid.JumpPower = 0
		wait(1)
        	humanoid:MoveTo(L1.Position)
		wait(1) 
		humanoid.Walkspeed = 16
		humanoid.JumpPower = 50
	end
end

script.Parent.Touched:connect(onTouched)

Suggestions

I recommend using CFrames rather than humanoid:MoveTo, and also changing game.Workspace to simply "workspace". With following these suggestions, THIS would be the final script:

local Hit = workspace.Model.Hit
local L1 = workspace.Model.L1
local End = workspace.Model.End  

function onTouched(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
	        local character = hit.Parent
		local torso = character.Torso
		local humanoid = character:WaitForChild("Humanoid")
		humanoid.Walkspeed = 0
		humanoid.JumpPower = 0
		wait(1)
        	torso.CFrame = CFrame.new(L1.Position)
		wait(1) 
		humanoid.Walkspeed = 16
		humanoid.JumpPower = 50
	end
end

script.Parent.Touched:connect(onTouched)
