ROBLOX Thread - how to detect objects with code

Hello robloxians!

you probably are searching for a way to test if things exist and some people have ideas on how to do so and they don't work.

well, I made a function to test for objects, their className, and any other property.




here is the code:

--Name

_G.exist = function(location, item)
	local children = location:GetChildren()
	local Return = nil
	for i = 1, #children do
		if children[i].Name == item then
			Return = true
		end
		if i == #children then
			if not Return == true then
				Return = false
			end
		end
	end
	return Return
end

--className

_G.existsOfClassName = function(location, item)
	local children = location:GetChildren()
	local Return = nil
	for i = 1, #children do
		if children[i].Name == item then
			Return = true
		end
		if i == #children then
			if not Return == true then
				Return = false
			end
		end
	end
	return Return
end

--Any property

_G.existsOfProperty = function(location, typeValue, typeName)
	local children = location:GetChildren()
	local Return = nil
	for i = 1, #children do
		if children[i][typeName] == typeValue then
			Return = true
		end
		if i == #children then
			if not Return == true then
				Return = false
			end
		end
	end
	return Return
end

--[[And remember:
	that the property for the existOfProperty function's 3rd parameter (the typeName parameter) has to be
	in quotes.
	,
	to use _G. [ function name ] () Instead of  [ function name ] () for example:
	_G.existsOfClassName
	Instead of:
	existsOfClassName.
	,
	that you only have to put all this code in a script and then you don't have to put it in every script
	you made just use _G. [ function name ] .
]]

If there are any errors or this code didn't work please reply that on this thread
