Asked Mar 25, 20201,201 views2 answers

I have a script that teleport player back to spawn (using loadcharacter) and reward 100 cash when a player touch a part This is my script:

local Debounce = false

script.Parent.Touched:connect(function(hit)
	if Debounce == false then
	Debounce = true
  	if hit.Parent.Humanoid ~=nil then 
		print("touched")
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + 100
		player:LoadCharacter()
		workspace.MapChanger.Waittime.Value = workspace.MapChanger.Waittime.Value /2	
		wait(5)
		Debounce = false	
		end
	end
end)

sometime when a player touch it, it give me an error saying Humanoid is not a valid player of Accessory then the script stop working... How can i prevent that?

Sorry for my bad english :(

To make script skip error and keep working, we use pcall(). For example:

local Succeed, ErrorMessage = pcall(function()
	write("I'm running in pcall() :D") --this will return error because the function have to be print() not write()
end)

if Succeed then
	print("Nothing wrong :D")
else 
	print("It error :(", ErrorMessage)
end

Succeed is a boolean value, if there is no error, it will return true or it will return false if there is error. ErrorMessage is the error message(duh...) that the script return if there is any error.
pcall() is only use for can't handle error like Http request error, Gamepass purchase,... but that is another thing.
Using pcall() too much is not a good habit, it better to fix the error by your self than skip it.

*Note: I don't have the link to pcall() document so... Find it your self :)

My script now print red color error line (without "It error :(") with a green line left to it.....Is that normal?

If that happen then you do it right. The green line left to it show is that line print by client or server(green mean server, blue mean client), and the red color error line is the ErrorMessage that you just print.

Hello. First, i will teach you how to check if something exists.

local hum = hit.Parent:FindFirstChild("Humanoid") --If it finds the humanoid, returns the humanoid, if it doesnt, returns nil
if hum then
	Hum exists!
end

Now, pcalls.

local worked, errormessage = pcall(function() --pcalls are functions that returns if it worked and the error message.
	pppprint()
end)
if worked == false then
	print(errormessage) --would print that pppprint() isnt a existant function or something. yeah.
end

Hope that helped!
