run_on_thread

Executes a function on a specific Luau thread (coroutineCoroutineA cooperatively-scheduled thread of execution in Luau. Each coroutine has its own lua_State (stack + call frames). Can be suspended with coroutine.yield() and resumed with coroutine.resume(). Roblox's task library uses coroutines internally.). Takes a thread reference and a function, then resumes the thread with the function injected into its execution context. This is lower-level than run_on_actor — it targets a specific lua_State rather than an Actor.

The function is pushed onto the target thread's stack and executed on the nextnext()Table traversal primitive. next(t, key) returns the next key-value pair after key, or nil when done. next(t, nil) returns the first pair. The underlying function used by pairs(). Traversal order is not guaranteed. scheduler cycle. The target thread must be in a yieldedYieldPausing a Luau coroutine/thread, returning control to the scheduler. The thread resumes later when the yielding condition is met (e.g., task.wait timer expires, HTTP response arrives). Implemented via coroutine.yield(). or suspended state. If the thread is currently running, the function is queued for deferred execution.
