Why Part.Touched is not working? everything look fine

Script:

print("a")
receptor.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		print("b")
		Eaten(receptor,hit)
	end
end)
print("c")

Output:

a
c

If you're expecting Touched to pass right off the bat and the output to have a, b, and c consecutively, this will never happen with the code you have. Touched is an RBXScriptSignal and will only run the code within a connected function if it successfully fires. It does not behave like an if statement nor does it behave like a loop.

With that being said, your output will ALWAYS look like this:

a
c
b
... -- other b's

Do you want the if to fire immediately after a is printed? You can put the print("c") after the print("b") to achieve an output of a, b, and c consecutively, respectively. If you don't, you're stuck with a, c, and then any b's for your output unless you put all 3 prints inside of the function.
