I want to make a “:tobool” function.

When I try to make it a bool for any word that is a string called true it gives me no errors

I want it to make a string from a variable/value or a string to true but it will not work. but when I try to make it any word with like true, True, TruE it only works for true same as false I have it inside my ModuleScript.

function functionMod:tobool(instanceVal)
	
	if instanceVal == "true" then
		instanceVal = true
	elseif instanceVal == "false" then
		instanceVal = false
	end
end

I changed it alot sorry wrong topic it was my old read it again sorry

Return the value instead. It doesn’t work since you are setting a string value to a boolean value.

function functionMod:tobool(instanceVal)
	
	if instanceVal == "true" then
		return true
	elseif instanceVal == "false" then
		return false
	end
end

-- Now to test it

local variable = "true"
variable = functionMod:tobool(variable)

Ok that also helped I just added it too

To add onto @Friendly4Crafter, to do what you wanted, check if what was given is a string and then use :lower() to lower case it

function functionMod:tobool(instanceVal)
	
	if type(instanceVal) ~= "string" then
		return nil
	end
	
	if instanceVal:lower() == "true" then
		return true
	elseif instanceVal:lower() == "false" then
		return false
	end
end

So it auto matically lowers it ok ima try

FrazedGreatness2 · May 25, 2021, 7:25pm

I am also trying to convert the string to a bool

EmbatTheHybrid · May 25, 2021, 7:26pm

Yes this will do as you want, it firsts checks if you passed in a string, and then lower cases that string and see if it equals to “true” or “false”

FrazedGreatness2 · May 25, 2021, 7:27pm

I know but it still prints this the string = to the variable which is this "True"

I will shpw all scripts rn

--module
function functionMod:tobool(instanceVal)
	
	if type(instanceVal) ~= "string" then
		return nil
	end
	
	if instanceVal:lower() == "true" then
		return true
	elseif instanceVal:lower() == "false" then
		return false
	end
end

--script
local functionMod = require(script.FunctionModule)

local trueval = "True"
functionMod:tobool(trueval)
print(trueval)

FrazedGreatness2 · May 25, 2021, 7:27pm

So instead of it being a string it goes straight to true or false so the bool

EmbatTheHybrid · May 25, 2021, 7:28pm

The way it works is that it returns it, right now you’re not caring about the return

local trueval = "True"
print(functionMod:tobool(trueval))

FrazedGreatness2 · May 25, 2021, 7:29pm

Ok but I am trying to change the variable so lets say it was true like this

local var = "TrUE"

-- i want it to convert to

local var = true

FrazedGreatness2 · May 25, 2021, 7:29pm

So instead of having to print the functionMod:tobool(var) I can just print the var

EmbatTheHybrid · May 25, 2021, 7:30pm

Then put the function as the assignment to truval…

local trueval = "True"
trueval = functionMod:tobool(trueval)

Ok lemme try that Sorry I am trying to make my own custom functions module for roblox
