Arbor 3.7.3

ExecutionEngineException occurs during runtime execution in IL2CPP build.

A bug that an exception occurs because the code of generic type and generic method is excluded by precompilation.

Status: Fixed in 3.7.4

It has become a specification for some problems that occurred in List.
See Ahead-of-Time (AOT) Restrictions for more information.

Provisional coping method

If it is occurring in DynamicUtiltiy

• Download the following zip file.
  Unity3.7.3_DyamicUtility_Patch
• Unzip and import into Unity project

When it occurs in the data flow of List

• Open Assets/Plugins/Arbor/Internal/Scripts/List/ListAccessor.cs
• Change line 371 as follows.

  public sealed class ListAccessorInternal<T> : ListAccessor
  

• Create an AOTCodeGeneration.cs file in the Assets / Scripts folder.
• Enter the following code.

  using UnityEngine;
  using UnityEngine.Scripting;
  using Arbor;
  
  [Preserve]
  public class AOTCodeGeneration
  {
  	public class AOTList<T>
  	{
  		public ListAccessorInternal<T> accessor = null;
  		public ListParameterBase<T> parameter = null;
  	}
  
  	public AOTList<Vector3> vectorList = new AOTList<Vector3>();
  	// Below, all types with exceptions
  }
  

Supplement

• Regarding ListAccessorInternal and ListParameterBase, we are verifying how to deal with it inside Arbor.
• Regarding generic types and generic methods outside Arbor such as List, notes will be described in the document.
