RE: Game oriented usage of Lua?

[Bret Mogilefsky <mogul@...>]

No, it's much simpler than that.  There's a multitasking primitive called
"break_here()" that simply sleeps the task until the next frame.  They look
something like the following... the "is_----ing()" functions call a C
function on the actor's engine handle to query some flags:

function Actor:wait_for_actor()
	while (self:is_moving() or self:is_turning() 
			or self:is_choring(nil, TRUE) or self:is_speaking()
) do
		break_here()
	end
end

(Yes, this is effectively polling the engine for state rather than more
efficiently calling explicitly back to Lua, but it works fine and the
overhead of Lua in the game itself is pretty miniscule anyway.)
