Why won't my weapon tag the player?
I'm trying to make a weapon that once it kills a player it will give it points. I have a script that will do that but it only works on linked swords that tag the player. I tried putting the tagging part of that script into my own but it ends up crashing the game and saying "attempt to call global 'tagHumanoid' (a nil value), line 10" I'm not sure what is happening...
local script
wait(0.01)
local CanDamage = true
local plr = game.Players.LocalPlayer
while true do
wait(0.01)
script.Parent.Touched:connect(function(hum)
if hum and hum.Parent:FindFirstChild("Humanoid") then
if CanDamage == true then
tagHumanoid(hum, plr)
CanDamage = false
hum.Parent.Humanoid:TakeDamage(10)
plr.swordlvl.Value = plr.swordlvl.Value + 2
wait(0.8)
untagHumanoid(hum)
CanDamage = true
end
end
end)
end
function tagHumanoid(humanoid, player)
local creator_tag = Instance.new("ObjectValue")
creator_tag.Value = player
creator_tag.Name = "creator"
creator_tag.Parent = humanoid
end
function untagHumanoid(humanoid)
if humanoid ~= nil then
local tag = humanoid:findFirstChild("creator")
if tag ~= nil then
tag.Parent = nil
end
end
end

The reason you're getting this error is because you define the functions tagHumanoid and untagHumanoid after the loop; so, while the loop is running, those functions do not exist. This can be easily remedied:
wait(0.01)
local CanDamage = true
local plr = game.Players.LocalPlayer
local function tagHumanoid(humanoid, player) --// Usage of local functions is recommended
local creator_tag = Instance.new("ObjectValue")
creator_tag.Value = player
creator_tag.Name = "creator"
creator_tag.Parent = humanoid
end
local function untagHumanoid(humanoid)
if humanoid ~= nil then
local tag = humanoid:FindFirstChild("creator")
if tag ~= nil then
tag.Parent = nil
end
end
end
while true do
wait(0.01)
script.Parent.Touched:connect(function(hum) -- Changed "part" to "hum"
-- local hum = part.Parent:FindFirstChild("Humanoid") Delete this
if hum and hum.Parent:FindFirstChild("Humanoid") then -- "hum" is the Player who touched the part/Sword.
if CanDamage == true then
tagHumanoid(hum, plr)
CanDamage = false
hum.Parent.Humanoid:TakeDamage(10) -- I forgot to add the "Parent.Humanoid" part after "hum"
plr.swordlvl.Value = plr.swordlvl.Value + 2
wait(0.8)
untagHumanoid(hum)
CanDamage = true
end
end
end)
end
Hope this helped!
PS: Your indentation was a bit off, so I went ahead and fixed it for you. In the future, it's a good idea to always properly indent your code so it's easier to read.
