gettenv - Mintlify Starter Kit

Returns the global environment table of a Lua thread - for a LocalScript thread, the exact same table getsenv(script) returns.

gettenv(t: thread): table

When t belongs to a LocalScript, gettenv(t) returns the same table as getsenv(script) (rawequal true). gettenv(t).script is the owning script, the same Instance getscriptfromthread(t) returns.

Parameters

Parameter	Type	Description
`t`	`thread`	The Lua thread whose environment to fetch.

Returns

table - the thread’s global environment. For a LocalScript thread it is identical (rawequal) to getsenv(thatScript): direct keys are the script’s own globals, Roblox globals (game, print, task) resolve through the metatable. Carries a .script field pointing at the owning script.

Example

In a Roblox game, confirm a thread’s environment is the same table as its script’s environment.

-- walk the registry, match each script thread back to its env
for _, thread in ipairs(getreg()) do
    if type(thread) == "thread" then
        local env = gettenv(thread)
        local owner = env.script

        if owner then
            print(`{owner:GetFullName()} -> {rawequal(env, getsenv(owner))}`)
        end
    end
end

Already holding the thread’s env table from gettenv(t)? Its .script field is the owning script - the same Instance getscriptfromthread(t) returns, without the extra call.
