I am trying to make a virus but i get, attempt to index nil with 'FindFirstChild' how to fix?
I am trying to make a code that infects players whenever they have the virus, but whenever i try to spread it , the outputs says: attempt to index nil with 'FindFirstChild'
local players = game:GetService("Players")
local player = game.Players.LocalPlayer.Character
player:WaitForChild("Humanoid").Touched:Connect(function(hit)
if(hit.Parent:FindFirstChild("Humanoid")) then
if not players:GetPlayerFromCharacter(hit.Parent):FindFirstChild("IsInfected")and players:GetPlayerFromCharacter(player):FindFirstChild("IsInfected") then
local infectedPlr = players:GetPlayerFromCharacter(hit.Parent)
local boolValue = Instance.new("BoolValue",infectedPlr)
boolValue.Name = "isInfected"
boolValue.Value = true
game:GetService("ReplicatedStorage").VirusUI:Clone().Parent = infectedPlr.PlayerGui
if game:GetService("ReplicatedStorage").VirusUI:Clone().Parent == infectedPlr.PlayerGui then
print("Player Has been infected")
end
end
end
end)

did the error occur at line 5 or 6, the output should say Gmorcad12345 434 — 4y

You have maybe forget a "end" for your if not, because I don't see it here Geohad0926 5 — 4y

There is no EOF exception. You may be using a Server-sided script, therefore, the LocalPlayer pointer won't refer to a Client affiliated Player Object. Ziffixture 6913 — 4y

there are. more than a few things wrong with this
the specific error is caused by you trying to call GetPlayerFromCharacter on the LocalPlayer
also, this should be a server script in StarterCharacterScripts, since changes made on the client don't replicate to the server, meaning that the other player never gets infected
local Players = game:GetService("Players") -- this isn't a super duper necessary thing but making services use PascalCase instead of camelCase makes it clearer what your code does, since it's pretty common practice
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local char = script.Parent
local player = Players:GetPlayerFromCharacter(char)
char:WaitForChild("Humanoid").Touched:Connect(function(hit)
local touchedPlayer = game.Players:GetPlayerFromCharacter(hit.Parent)
if touchedPlayer and hit.Parent:FindFirstChild("Humanoid") and not touchedPlayer:FindFirstChild("IsInfected") and player:FindFirstChild("IsInfected") then -- you only need one if statement for this
local boolValue = Instance.new("BoolValue", touchedPlayer)
boolValue.Name = "IsInfected"
boolValue.Value = true
game:GetService("ReplicatedStorage").VirusUI:Clone().Parent = touchedPlayer.PlayerGui
print("Player has been infected") -- there's no reason to check if the gui was cloned, since it'll ALWAYS be cloned no matter what

the "end" is there, plus the error is referring to 'findfirstchild' not expected eof Gmorcad12345 434 — 4y
