Reconfigure a state

[Ninho67]

Hi guys and thanks for the good work.

I have a particular case that I am not capable of solving and need your help. I have several state machines defined with Stateless and some of them have inheritance:

• StateMachineA
• StateMachineB
• StateMachineC

Each class has a ConfigureStateMachine() method where I do all the wiring of triggers for each state. Now if I have the following inheritance schema:

A <|- B <|- C

where some triggers defined for B are not valid for C (but the state machines are identical at 95%).

To illustrate:

// StateMachineA
// ...

protected virtual void ConfigureStateMachine()
{
    // Idle
    IdleStateConfiguration = StateMachine.Configure(MachineExecutionState.Idle);
    IdleStateConfiguration.Permit(StateTrigger.Collision, MachineExecutionState.Suspended);

    // ...
}

// StateMachineB
// ...

protected override void ConfigureStateMachine()
{
    // Idle
    // Here I'm only extending the base state machine, OK
    IdleStateConfiguration.Ignore(StateTrigger.Start);

    // ...
}

// StateMachineC
// ...

protected override void ConfigureStateMachine()
{
    // Idle
    // This won't work because because I have conflicting exit transitions
    IdleStateConfiguration
         .Permit(StateTrigger.Start, MachineExecutionState.Suspended);

    // ...
}

I would like to reset all the wirings of a state so that I can redefine it down the inheritance tree.
The only solution I have so far is to drop the inheritance, duplicate B and do the 5% changes that I need to have C. It is no big deal for small state machines but mine is really big.

Any chance we can get this feature in next release ?

Thanks
