It is different!

Remember that "false" and "true" are boolean values.

--Boolean overview
local myBool = true

if myBool == true then 
    print("my bool is true!")
else
    print("my bool is false!")
end

Experiment with that a little!

On to the "return" part.

Returning is a step in a function which: exits the function, and passes value(s) back to the caller.

So let's try it out with a less than 10 function!


function isLessThanTen(num)
    if num < 10 then
        return true
    else
        return false
    end
end

print(isLessThanTen(5))
print(isLessThanTen(100))

First print output: true, second one is false AntoninFearless 622 — 4y

Correct, which means we now have a function that can tell whether o not a number is less than 10! Think of it like a sentence: 5 Is less than ten? 100 Is less than 10? Vathriel 510 — 4y

return (num < 10) also works xD Ziffixture 6913 — 4y

Correct but that's not the point of what he asked. Vathriel 510 — 4y

no its not really different it depends on the conditions its being returned to like

function food()
    return true
end
if food then
    --eats
end

--or

function food()
    return false
end
if not food then
    --does not eat
end

if not food then meaning false and if food then is basically saying if food is true Vetrodex 22 — 4y

or if food == 1 or if food == 0 (true or false) so its not really different its just based on how you use it in your conditions Vetrodex 22 — 4y
