Am I using pcall correctly?
I just recently came across someone using pcall and tried to implement it into my script so that no errors are produced, am I using this correctly?
script.Parent.Touched:connect(function(hit)
pcall(function()
humanoid = hit.Parent.Humanoid--this produced an error if it wasn't touching a player/humanoid, but its fine now that i put it in this pcall
end)
if humanoid then
humanoid.Health = humanoid.Health - damage
end
end)
This script works, but is there a way to improve it?
EDIT: i just realized I could use
local humanoid = hit.Parent:FindFirstChild("Humanoid")
instead, but could someone explain me to where i should use pcall

Pretty sure it is, but a pcall's main usage is to catch any errors while running and inform the developer about it in the output. This is useful so that the code doesn't error and stop. This would be better to use:
script.Parent.Touched:connect(function(hit)
local success, errorMesage = pcall(function()
humanoid = hit.Parent.Humanoid
end)
if humanoid then
if success then
humanoid.Health = humanoid.Health - damage
else
print("There was an error in the pcall.")
warn(errorMessage)
end
end
end)
