Hey @Droidz

through my plugin, I want to add some states of my own (mostly for custom training etc).
Unfortunately, when doing this OnEngineStart event, I always get:
 

[E] 13:50:08 - Engine > Pulse(): System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
   at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)
   at System.Collections.Generic.List`1.Enumerator.MoveNextRare()
   at System.Collections.Generic.List`1.Enumerator.MoveNext()
   at robotManager.FiniteStateMachine.Engine.Pulse()

which makes sense. Is there any way to add my own states, currently? I couldn't find any event that fires before EngineStart and I am sure I'm not modifying the collection DURING Pulse on another thread.

Hello, you use AddState ? 

robotManager.Events.FiniteStateMachineEvents.OnStartEngine += engine =>
{
    engine.AddState(MyState);
};

 

Yeah, I only get the exception once and then it works. All good.
