Does component's field not support enum?

[vkensou]

entityConverter.DataEntityToEntityPreserve report error message, if a component contain a enum field.

Sure, component fields using an enum are supported.

You are using an EntityConverter. So your question is is more specific.
"Can component field's with an enum type serialized to JSON?"

This is also supported.

Made a small example see:
https://github.com/friflo/Friflo.Engine.ECS/blob/main/src/Tests/ECS/Serialize/Test_Serialize_enum.cs

• Please paste the error
• Can you create a test case like above?
• Are you using Unity?

I am using unity. my code like:

    public enum TestEnum
    {
        None = 1,
        Foo = 2,
    }

    public struct ComponentUseEnum: IComponent
    {
        public TestEnum testEnum;
        public int num;
    }

There are 2 issues:

1. unity inspector not show the testEnum.
   

2. when load scene(or press play button), there is a error report, then components are all lost.

'components' element must be an object. was Error. id: 1, component: 'testEnum'
