Unity SerializeReference Property Drawer

Convenient property drawer for fields marked with the SerializeReference attribute.

Installation

Installation as a unity module via a git link in PackageManager or direct editing of `Packages/manifest' is supported.json:

"com.elmortem.serializereferenceeditor": "https://github.com/elmortem/serializereferenceeditor.git",

Main types

SRAttribute

Use it to mark the fields that you want to edit. Important note - they should also be marked with the SerializeReference attribute. You can mark the base type (including the interface) with it. Allows you to change an array, a list, and a single element. Displays the current field type.

Example:

[SerializeReference]
[SR]
public List<AbstractData> DataList = new List<AbstractData>();

Result:

Additional features

You can override SRAttribute and implement a rule for processing instantiated objects.

You can see an example in SRDemoAttribute.cs, where the OnCreate method was overriden:

public override void OnCreate(object instance)
{
    if(instance is AbstractData)
    {
        ((AbstractData)instance).DataName = instance.GetType().Name;
    }
}

SRNameAttribute

Mark classes with them if you want to customize the display name and nesting hierarchy in the search tree for a specific type.

Example FloatData.cs:

[SRName("Data/Simple types/Float")]  
public class FloatData : AbstractData
{
    [Range(0f, 1f)]
    public float Float;
}

You can modify the display settings for the class name without specifying an attribute by navigating to Edit -> Project Settings -> SREditor.

Tools

MissingTypesValidator

You can use the built-in tool to search for lost types. (this error occurs if the serialized data stores information about a type that no longer exists and could have been deleted during development). To start, you can run Tools -> SREditor -> Check MissingTypes

At least one SRMissingTypesValidatorConfig is required to work. If necessary, you can implement your own IAssetMissingTypeReport for error reporting if you use it in CI/CD systems. You can also implement your own IAssetsLoader if the default LoadAllScriptableObjects is not suitable for you.

Support Unity 2019.3 or later.

Use for free.
