Call Function in Yielded Lua Thread

Hi,

This is yet another question about lua threads. I’ve been looking though the archives but haven’t been able to find exactly what I’m looking for.

What I have is a main lua script that I create new states from using lua_newstate, one for each object that has a script. I have registered a wait() function so that the thread can be yielded and resumed. The wait() function is a C function that calls lua_yield() before returning.

The yield and resume all works fine.

What I don’t quite understand is how to call other functions inside a script that has been yielded. Example:

-- lua script

function onHit()

playAnim()

wait(10)

playAnim2()

end

function onActivate()

while 1==1 do

moveTo(….)

wait(10)

playAnim()

cameraShake()

wait(10)

end

So after calling onActivate I want to be able to call the function onHit.

I call my functions from C something like this:

lua_getglobal(L, “onActivate”);

lua_resume(L, 0);

Sorry if this has been covered already. Any pointers to how to setup Lua to work like this would be much appreciated.

Thanks!
