NCCreateDelegate Exception

[Arie van Someren]

I have a parralel composite which will scan for user actions, one of which is the EndTurn action which will wrap up the players turn and give control to the next player.

Trying to do this i am experiencing some difficulties using a “check c# event” condition. I have added an EventHandler to my behaviour which will be invoked when clicking a UI button. I would like to “catch” the invoked handler and act accordingly.

public event EventHandler EndTurn;         public void OnEndTurn()         {             EventHandler handler = EndTurn;             if (handler != null) handler(this, EventArgs.Empty);         }

The problem is that the delegate is not added to the inocation list of the eventhandler. An exception is thrown wil attempting to create the delegate from within the condition.

ArgumentException: method argument length mismatch System.Delegate.CreateDelegate (System.Type type, System.Object firstArgument, System.Reflection.MethodInfo method, Boolean throwOnBindFailure) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System/Delegate.cs:226) System.Delegate.CreateDelegate (System.Type type, System.Object firstArgument, System.Reflection.MethodInfo method) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System/Delegate.cs:276) NodeCanvas.NCReflection.NCCreateDelegate (System.Reflection.MethodInfo method, System.Type type, System.Object instance) (at Assets/NodeCanvas/Core/Other/NCReflection.cs:252)

Any clue on what could be causing this?

Apparently it was EventArgs that were causing the issue. I opted for a different direction creating my own custom condition assigning the delegate to the behaviour manually. Which works like a charm.

Consider it closed 😉
