Edited 6 years ago

I tried to get the data value but the script won't update when it changes. For example, while the output is printing same value, I changed the numb value to 1 but the script still thinks that numb.value = 0. Here is my script(It has to be a function)

1function example()
2    data = game.Workspace.Numb.Value
3    while data == 0 do
4        print("same value")
5    end
6    print("value = 1")
7end
8example()

is your "data" variable not changing? If not then I can answer User#24403 69 — 6y

yes superbolt999 36 — 6y

So the issue is that the data variable isn't updating? User#24403 69 — 6y

yea superbolt999 36 — 6y

If i helped you out can you please accept my answer? It means a lot User#24403 69 — 6y

Reference

In Lua, for example, tables are passed by reference.

01local tbl1 = {"hello", "world", "foo", "bar"}
02local tbl2 = {"hello", "world", "foo", "bar"}
03local tbl1reference = tbl1
04table.insert(tbl1, "test")
05 
06for _, v in ipairs({tbl1, tbl2, tbl1reference}) do
07    print(table.concat(v, ", "))
08end
09 
10--[[
11    output:
12   hello, world, foo, bar, test
13   hello, world, foo, bar
14   hello, world, foo, bar, test
15 
16--]]

tbl1 and tbl1reference hold the same exact table in memory and tbl2 does not, even if it has the same values in the same positions. Changes made to tbl1 or tbl1reference will affect tbl1 and tbl1reference.

Value

However things like booleans and numbers are passed simply via value.

01local _string = "hello"
02local _string_value = _string
03_string = "world"
04print(_string_value)
05 
06local bool1 = false
07local bool1_val = bool1
08bool1 = true
09print(bool1) --> true
10print(bool1_val) --> false 

Even though _string_value was set to _string, both variables have different memory and modifying one value does not change the other.

Final product

1local numb = game.Workspace.Numb
2 
3local function example()
4    while numb.Value == 0 do
5        print("same value")
6    end
7    print("value = 1")
8end
