Attempt to index nil bug

Help and Feedback Scripting Support
#1

I was watching a tutorial on a combat system and I am having a problem with a script that is the exact same to the script on the tutorial but gives me an error. This is the script.

local MuchachoHitbox = require(game.ServerStorage.modules["MuchachoHitboxV1.1"])
local HitService = require(game.ServerStorage.modules.HitService)
local CombatTable = require(game.ServerStorage.modules.CombatTable)

--print(CombatTable)
--[[game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(character)
	character:SetAttribute("Combo", 1)
end)
end)--]]
local remote = game.ReplicatedStorage:WaitForChild("CombatEvent")
local lastremote = game.ReplicatedStorage:WaitForChild("LastHit")
local MaxCombo = 5

local function SetCombo(CV)
	local combo = CV.Combo
	
	if combo < MaxCombo then
		CV.Combo += 1
	else
		CV.Combo = 1
	end
end

local function ComboReset(CV, oldcombo)
	task.delay(1, function()
		local currentcombo = CV.Combo
		
		if oldcombo == 5 then return end
		
		if currentcombo-1 == oldcombo and not CV.Attacking then
			CV.Combo = 1
		end
	end)
end

remote.OnServerEvent:Connect(function(player)
	local character = player.Character
	local humanoid = character:WaitForChild("Humanoid")
	local rootpart = humanoid.RootPart
	local animator = humanoid.Animator
	
	local Attributes = CombatTable[character]
	
	local combo = Attributes.Combo
	local attacking = Attributes.Attacking
	local stunned = Attributes.Stunned
	local blocking = Attributes.Blocking
	
	
	if attacking or stunned or blocking then return end
	Attributes.Attacking = true
	
	local animations = game.ReplicatedStorage["punch anims"]:GetChildren()
	local animation = animator:LoadAnimation(animations[combo])
	
	local hitbox = MuchachoHitbox.CreateHitbox()
	hitbox.Size = Vector3.new(6,6,6)
	hitbox.Offset = CFrame.new(0,0,-2.5)
	hitbox.CFrame = rootpart
	--hitbox.Visualizer = false
	
	task.delay(.25, function()
		ComboReset(Attributes, combo)
		hitbox:Stop()

		if combo == 5 then

			humanoid.WalkSpeed = 5
			task.wait(1)
		end
		humanoid.WalkSpeed = 16
		Attributes.Attacking = nil
	end)
	
	hitbox.Touched:Connect(function(hit, hum)
		if hum == humanoid then return end
		
		local function fx()
			local effectsFolder = game.ReplicatedStorage.fxfolder
			
			local attachment = Instance.new("Attachment")
			attachment.Parent = hum.RootPart
			
			local particle = effectsFolder.hitfx:Clone()
			particle.Parent = attachment
			particle:Emit(5)
			
			local sound = effectsFolder.hitsfx:Clone()
			sound.Parent = attachment
			sound:Play()
			
			local hitanims = game.ReplicatedStorage["hit anims"]:GetChildren()
			local hitanim
			
			if combo == 1 or combo == 3 then
				hitanim = hum:LoadAnimation(hitanims[1])
			elseif combo == 2 or combo == 4 then
				hitanim = hum:LoadAnimation(hitanims[2])
			elseif combo == MaxCombo then
				hitanim = hum:LoadAnimation(hitanims[3])
			end
			
			hitanim:Play()
			
			game.Debris:AddItem(attachment, .1)
			game.Debris:AddItem(sound, .3)
		end
		
		if combo < MaxCombo then
			HitService.Hit(hum, 5, .1, rootpart.CFrame.LookVector*10, false, fx)
		else
			HitService.Hit(hum, 10, .3, rootpart.CFrame.LookVector*100, true, fx)
		end
		
	end)
	
	humanoid.WalkSpeed = 7
	animation:Play()
	task.wait(.16)
	hitbox:Start()
	
	SetCombo(Attributes)
	
end)

The error is :

What does CombatTable and CombatTable[character] return?
Print both of them.

Also please comment the line that caused the error, instead of me manually counting every line.

Line 43 defines the Attributes as: local Attributes = CombatTable[character]

Line 45 is: local combo = Attributes.Combo

On line 45 the variable Attributes is nil because line 43 is not working.

#4

that’s being returned because Player.Character might’ve returned nil

#5

do you have any idea why 43 isn’t working?

#6

is there any solution? i really dont have any experience in scripting and this is my first real try at making a game

#7

the lines are
43 -

local Attributes = CombatTable[character]

45 -

local combo = Attributes.Combo

here’s what comes out when i print the tables

#8

So Attribute is nil, and the table doesn’t have the Player’s character in that.
Could you elaborate on why are you trying to do CombatTable[character].

#9

the keys in the combat table are strings. player.Character is an instance. You can get the name of the instance with .Name

change it to CombatTable[character.Name]

#10

i dont know, in the tutorial he didnt explain why he wrote that line and it works perfectly fine for him. the like was originally

Local Attribute = CombatTalbe[player.Name]

but it still showed the nil error

#11

it still didn’t work and the line was originally

Local Attribute = CombatTalbe[player.Name]

it worked perfectly find for the guy in the tutorial.

#12

I figured out the problem, in CombatTable, I put the table to find out the player’s name when i could’ve just put it to find the character. The code was originally, (“t” is table, “p” is player.) -

game.Players.PlayerAdded:Connect(function(p)
	p.CharacterAdded:Connect(function(c)
           t[p.Name] = {
             --attributes n stuff
           }
    end)
end)

the fixed version is

game.Players.PlayerAdded:Connect(function(p)
	p.CharacterAdded:Connect(function(c)
           t[c] = {
             --attributes n stuff
           }
    end)
end)
