Q
Is there a possibility to program a kind of "state machine" via functions?
A
Like variables also functions are handled internally as tables. A function thus has a name and a value. This value can be changed during runtime and hence decide which function will be called next.
Example code:
if myfunc then
myfunc()
else
-- defining all subfunctions
function my_state_init_done()
..
myfunc = my_state_1
end
function my_state_1()
..
myfunc = my_state_2
end
function my_state_2()
..
myfunc = my_state_init_done
end
myfunc = my_state_init_done
end
