Why does error come eventhough script itself works fine?
When i made a kill block with script, the output executes error that says : 11:28:55.932 - Workspace.Basic traps and power ups tutorial.Trap.Script:7: attempt to index local 'humanoid' (a nil value).
However, the script itself works fine and it does make humanoid health to 0. Can someone help me to know what is the error with this script?
local trapPart = script.Parent
local function onPartTouch(otherPart)
local partParent = otherPart.Parent
local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
if ( "humanoid" ) then
-- Set player's health to 0
humanoid.Health = 0
end
end
trapPart.Touched:Connect(onPartTouch)

I believe you use the wrong syntax. In the if statement (Where it says if ("humanoid") then),the if statement is confirming the string: humanoid, not the variable: humanoid. Also, you do not need to use :FindFirstChildWhichIsA(), but it is totally up to you. Thus, the script would be:
Without :FindFirstChildWhichIsA()
local trapPart = script.Parent
local function onPartTouch(otherPart)
local partParent = otherPart.Parent
local humanoid = partParent:WaitForChild("Humanoid")
if humanoid then -- Set player's health to 0
humanoid.Health = 0
end
end
trapPart.Touched:Connect(onPartTouch)
With :FindFirstChildWhichIsA()
local trapPArt = script.Parent
local function onPartTouch(otherPart)
local partParent = otherPart.Parent
local humanoid = parentParent:FindFirstChildWhichIsA("Humanoid")
if humanoid then -- Set player's health to 0
humanoid.Health = 0
end
end
Accept my answer if it works for you!
Hi Yuuwa0519, the reason because your code don´t executes as well is because you are using a string as condition if ("humanoid") instead of if (humanoid).
Fix:
local Trap = script.Parent
Trap.Touched:Connect(function(instance)
local Humanoid = instance.Parent:FindFirstChildWhichIsA("Humanoid")
if Humanoid then
Humanoid["Health"] = 0
end
end)
I believe you're not following the syntax of Roblox.
local trapPart = script.Parent
local function onPartTouch(otherPart)
local partParent = otherPart.Parent
local humanoid =
partParent:FindFirstChildWhichIsA("Humanoid")
if ( humanoid ) then
-- Set player's health to 0
humanoid.Health = 0
end
end
trapPart.Touched:Connect(onPartTouch)
"humanoid" wouldn't work because that's a string. You want to check to see if the variable exists, not the string. So this should fix your issue.
