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;
    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


  • 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.
