[NC2] AoT Error on iOS with BBParameter set value

[Matt Newcombe]

Hi There,

I’ve hit a JIT error on iOS for the use of reflection in NC2. My game code basically looks like the following:

1 2	public BBParameter<float> remainingCharge; remainingCharge.value = GameController.batteryModel.chargeAmount;

When invoked I get the following stack:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

ExecutionEngineException: Attempting to JIT compile method 'NodeCanvas.Framework.Variable1<single>:.ctor ()' while running with --aot-only.     at System.Reflection.MonoCMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 Rethrow as TargetInvocationException: Exception has been thrown by the target of an invocation.   at System.Reflection.MonoCMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0   at System.Reflection.MonoCMethod.Invoke (BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0   at System.Reflection.ConstructorInfo.Invoke (System.Object[] parameters) [0x00000] in <filename unknown>:0   at System.Activator.CreateInstance (System.Type type, Boolean nonPublic) [0x00000] in <filename unknown>:0   at System.Activator.CreateInstance (System.Type type) [0x00000] in <filename unknown>:0   at NodeCanvas.Framework.Internal.BlackboardSource.AddVariable (System.String varName, System.Type type) [0x0006d] in /Users/matthew.newcombe/work/frodo/Client/Assets/NodeCanvas/Framework/Variables/Internal/BlackboardSource.cs:84   at NodeCanvas.Framework.Internal.BlackboardSource.AddVariable (System.String varName, System.Object value) [0x00012] in /Users/matthew.newcombe/work/frodo/Client/Assets/NodeCanvas/Framework/Variables/Internal/BlackboardSource.cs:63   at NodeCanvas.Framework.Internal.BlackboardSource.SetValue (System.String varName, System.Object value) [0x00063] in /Users/matthew.newcombe/work/frodo/Client/Assets/NodeCanvas/Framework/Variables/Internal/BlackboardSource.cs:130   at NodeCanvas.Framework.Blackboard.SetValue (System.String name, System.Object value) [0x00000] in /Users/matthew.newcombe/work/frodo/Client/Assets/NodeCanvas/Framework/Variables/Blackboard.cs:91   at NodeCanvas.Framework.BBParameter1[System.Single].set_value (Single value) [0x0003a] in /Users/matthew.newcombe/work/frodo/Client/Assets/NodeCanvas/Framework/Variables/BBParameter.cs:255

Which means I am unable to run some of this code on iOS

I have another JiT issue I’ll post in a seperate thread
