The same thing, different results?

Asked 125 views1 answers

Recently I was working with a script using values and encountered a problem. I noticed that values don't change when using variables. Here is what I mean:

local value = script.TEST.Value --test being an intvalue

value = value +1

I noticed this did not change the value. Value is still 0. However if I write what I think is the exact same thing:

script.TEST.Value = script.TEST.Value +1

Guess what? Value changed! It is now equal to 1.

I have looked online for a bit and not found anything regarding this, I am really confused why this is happening. Could anybody explain?

First script is changing the value variable itself, whilst the second script gets the value and adds it to that value.

Also, the first and second script is not the same thing.

When you do value = value + 1, your not changing the Value property of Test. Your actually assigning a new Value to the variable.

local Variable = script.TEST.Value 

Variable = Variable + 1 -- Same as: Variable = script.Parent.Value + 1
print(script.Parent.Value) -- prints 0, through this entire script, the value has never been changed.
print(Variable) -- prints 1, Variable's value has been changed on line 3.
