Entering and exiting state

[lukors]

Is it possible to enter/exit a state right away?

So let's say I'm in MyState::StateTwo, and I want to exit and enter the state. I was hoping I could do this:

my_state.push(MyState::StateOne);
my_state.push(MyState::StateTwo);

But seems like it can't have more than one state queued at a time?

What I'm actually trying to accomplish is to run the with_run_criteria(State::on_enter(MyState::StateTwo)) functions again if the state is already active, and would prefer to not have to add special code for this.

My PR (#3328) regarding this issue was recently merged. That's probably what you need.

Yeah that would make my case significantly better! :)

I could do something like this:

if let StateError::AlreadyInState = my_state.overwrite_replace(MyState::StateTwo) {
    my_state.overwrite_restart() 
}

It would be even better with something like a my_state.push_or_restart(); that does this in one function call, but I can do without. :)

Thanks! :D
