How do I carry a variable past 'Until'?
I'm trying to have the game select two children from a model. I want it to select one, then select a different one (such as two flavors of tea). The script for choosing the first works perfectly, but then I have it chose a second item using a Repeat (in case it chooses the first object again, as I want two unique choices). However, the chosen2 variable is 'nil' when I ask it to print after 'until.' I feel like I may be missing something obvious here but I'm not sure. Any explanation for this?
01 | function Choose2 (Chosen1) |
02 | print (Chosen1) --prints the name of the first chosen object fine, such as "Peppermint" |
03 | repeat |
04 |
05 | local Chosen2 = (Items[math.random(1,#Items)]) |
06 | print(Chosen2) -- prints the name of the second chosen object fine, such as "Earl Grey" |
07 | until Chosen2 ~= Chosen1 |
08 | print (Chosen2) -- prints nil |
09 |
10 |
11 |
12 | end |

Like Painter said it's much better removing the values from your table and getting a random value out of that, however you should never edit the original table otherwise you'll lose your values forever. Instead I recommend making something called a "shallow copy".
It's basically a clone of your original table key and value pairs, only thing we need to do is make sure that Chosen1 is not within this clone which is easy:
01 | local teas = {"Mint", "Grey", "Strawberry", "God knows what"} |
02 |
03 | local first = teas[1] -- This would be the Chosen1 value |
04 |
05 | function Choose2(Chosen1) |
06 | local otherTeas = GetTableWithout(teas, Chosen1) |
07 | print(unpack(otherTeas)) |
08 |
09 | local Chosen2 = otherTeas[math.random(1, #otherTeas)] |
10 | print(Chosen1) |
11 | print(Chosen2) |
12 | end |
13 |
14 | function GetTableWithout(t, value) |
15 | local t2 = {} |
This is the basic idea behind it
