Sandboxing local variables using setfenv?
This prints 5 and then 6. It's supposed to add 1 to any variable set, so a should be 6 and b should be 6, but __newindex doesn't affect a because it was declared locally. Is there any way to filter local variables?
01 | do |
02 | local e={print=print} |
03 | setfenv(1,setmetatable({},{ |
04 | __index=function(t,k) |
05 | return e[k]or loadstring('return '..k)() |
06 | end, |
07 | __newindex=function(t,k,v) |
08 | e[k]=v+1 |
09 | end |
10 | })) |
11 | end |
12 |
13 | local a=5 |
14 | print(a) |
15 |
16 | b=5 |
17 | print(b) |

Local variables can't be found unless you're using the debug library; here But it's useless in ROBLOX.

Isn't the debug library only Lua 5.2? 1waffle1 2908 — 11y

There are other ways to sandbox, (Obv), I have seen a few.. My friend is INSANE at sandboxing.. If you still need help ask LordRevorius and tell him I sent you. MessorAdmin 598 — 10y
