Not giving output When running LocalScript inside of StarterGui - lua

Question

So, Im tring to make a Mind Control script inside of Roblox. Im using the local script so i can use the UserInputServer Module. But When I Run It(Its inside of StartGui), I doesn't give any output. Here is the source:
--Made By BioShot!--
local UIS = game:GetService("UserInputService")
local Enabled = false
local Active = false
game.Players.PlayerAdded:Connect(function(plr)
print("Player Added!")
UIS.InputBegan:Connect(function(input)
if(input['KeyCode'] == Enum['KeyCode']["E"]) then
if(Enabled == true) then
--Rase Player/Dummy/NPC
local Mouse = plr:GetMouse()
Active = true
while(Active == true) do
local Enemy = Mouse["Target"]
print(Enemy)
Enemy.CFrame = Enemy.CFrame + CFrame.new(0,1,0)
wait(0.5)
end
else
--Drop Player/Dummy/NPC
end
end
end)
UIS.InputEnded:Connect(function(input)
if(input['KeyCode'] == Enum["KeyCode"]["F"]) then
Enabled = true
print("Enabled.")
end
if(input['KeyCode'] == Enum["KeyCode"]["E"]) then
Active = false
end
end)
end)

Answer 1

The statements are only printed after game.Players.PlayerAdded:Connect(function(plr) detects a player being added. Due to the code running in a LocalScript, the player will have already been added by the time the script starts waiting for players. If a second player joins the game, "Player Added!" will indeed be printed in the first player's console.
The player can instead be indexed by using local plr = game:GetService("Players").LocalPlayer.
The script still errors when the player's mouse is pointing to nothing and when trying to change the Enemy's position, but these can be easily fixed. The script then lifts objects upwards by hovering over them and pressing E.
Final code:
--Made By BioShot!--
local UIS = game:GetService("UserInputService")
local Enabled = false
local Active = false
local plr = game:GetService("Players").LocalPlayer
print("Player Added!")
UIS.InputBegan:Connect(function(input)
if(input['KeyCode'] == Enum['KeyCode']["E"]) then
if(Enabled == true) then
--Rase Player/Dummy/NPC
local Mouse = plr:GetMouse()
Active = true
while(Active == true) do
local Enemy = Mouse["Target"]
if Enemy then --Make sure the player's mouse isn't pointing to nothing
print(Enemy)
Enemy.CFrame += Vector3.new(0,1,0)
end
task.wait(0.5) --More accurate than wait(0.5)
end
else
--Drop Player/Dummy/NPC
end
end
end)
UIS.InputEnded:Connect(function(input)
if(input['KeyCode'] == Enum["KeyCode"]["F"]) then
Enabled = true
print("Enabled.")
end
if(input['KeyCode'] == Enum["KeyCode"]["E"]) then
Active = false
end
end)
