Are callbacks run in parallel?
 
I have an array that I modify in the OnUpdate handler. Somewhere else in the code, I call the method C_Timer.After, altering that same array after N milliseconds.

Here's my question: Will the callback run in parallel with OnUpdate, and thus risking both methods changing the array at the same time? Or does it run sequentially?

Lua is a single thread language, so going without testing, I'd say sequential.

The entire Lua engine is in a single thread run by the renderer. While the coroutine library does offer thread-like functionality, it's not async. This means it blocks execution of the caller until it yields, pausing its own execution until it's called again.
