How do the BeforeStates and NextStates work?

Mainly targeted @Droidz but if anyone else has input, you're welcome to contribute.

The state interface has BeforeStates and NextStates. My question is when do they run and does their "Need To Run" condition get checked?

If you add the state into the list of before or after states are they in the main engine list of states or are they only considered if the state you added the before/afterstates to, is triggered?

Hello, like that (in simplified):

bool RunState(State currentState)
{
	if (currentState.NeedToRun)
	{
		foreach (var beforeState in currentState.BeforeStates)
		{
			RunState(beforeState);
		}
		
		currentState.Run();
		
		foreach (var nextState in state.NextStates)
		{
			RunState(nextState);
		}
		
		return true;
	}
    return false;
}

Ah okay, thanks. One more thing though does the 

RunState(beforeState);

check the beforeStates NeedToRun or does it just run it anyway?

Method check if needtorun return true (it is the method than I shared code)

Yeah I saw that, very useful. I was more wondering about the actual states interface implementation of Before/NextStates rather than the events though.
