Title: another statemachine question... Post by: marcink on March 02, 2009, 09:01:30 is it possible to nest states?
say i have 4 states: state A, state B, state C and state D when in state B, i'd like to have the possiblity to trigger state C and state D, but only if i'm in state B. when i would try to trigger state C/D while the current state is A, nothing happens... is that possible? or do i have to make a switch in the handleNotification function? thanks Title: Re: another statemachine question... Post by: Neil Manuell on March 02, 2009, 03:46:10 consider this:
<fsm initial='A'> <state name='A'> <transition action='toB' target='B'/> </state> <state name='B'> <transition action='toC' target='C'/> <transition action='toD' target='D'/> </state> <state name='C'> <transition action='toA' target='A'/> </state> <state name='D'> <transition action='toA' target='A'/> </state> </fsm> if the state is B, you can go to C or D (be calling ACTION 'toC' or 'toD') however in A calling these ACTIONS would do nothing. You would have to call 'toB' to change state, as the only legal state that you can go to from A is B does that answer your question? Title: Re: another statemachine question...
