Yup, "threads" in this case are really lua coroutines so they never run truly in parallel, instead they yield while another coroutine run.

As i do in my mod, you can call Waitseconds() in simside with ForkThreads which is very usefull. Because SimSide is by event leaded, and a timed thread can be usefull.

Think you can't WaitSeconds unless you are in a forked thread. Maybe you can't do it sim side not sure.

Yeah - don't worry about shared variables... you don't have to lock them.

Ty for your reply Ani. This time i need threads to catch information by time (in my case every 2 s) in the simside.
In fact i hooked the DoTakeDamage function. And i can't put a Waitseconds() function. It seems that you can't call Waitseconds() functions everywhere. It's logical, you can't slow the process.

But my thread is working well, i was just wondering if need to spend time to take care of shared variables. If lua threading is a trick, maybe not ^^

I think it's not a real thread, just a trick. Otherwise couldn't stay in sync?

Lua ForkThread / MultiTreading - Accessing data

2016-03-06T21:49:32+02:00

Hi,

I'm still working on my mod, and i asking myself if i need to worry about accessing variable between my threads.

I currently wrote a thread (with ForkThread) that erase a datatable each 2s. This datatable is modified outside my thread. For now, i run my erasing thread only when the datatable is not being modified.

But i m asking if i need to worry myself, as it seems that lua is not really multithreaded capable. I've got no error when i access my datatable anywhere anytime by any of my thread.

Am i lucky, or is lua not really multithreading capable, or should i take care (i found no documentation about the ForkThread function) ?

Any idea ? It should reduce the time i need to develop my mod.
