IPropertyDatabaseView.IsPersistableType

パラメーター

戻り値

bool True if the type can be persisted in the file, false otherwise.

説明

Returns a boolean indicating if a type can be persisted into the backing file.

Only certain types can be persisted in the backing file to survive a domain reload and quitting Unity. However, any type can be stored without backing in the PropertyDatabase. You can always decompose your custom objects into smaller properties that can be persisted if you absolutely need persistence.

// Any object can be stored in the property database, but only
// some of them will be persisted in the database file. All others
// will disappear after the current Unity session. If you absolutely need your
// data to be persisted, you can decompose your it into smaller properties that can
// be serialized.
using (var view = propertyDatabase.GetView())
{
    var customTypeValue = new MyCustomType(42, "myValue");
    if (view.IsPersistableType(typeof(MyCustomType)))
    {
        var stored = view.Store("path/to/my/asset", "m_customTypeValue", customTypeValue);
        if (!stored)
            Debug.LogWarning("Property m_customTypeValue did not store.");
    }
    else
    {
        var stored = view.Store("path/to/my/asset", "m_customTypeValue.value", customTypeValue.value);
        if (!stored)
            Debug.LogWarning("Property m_customTypeValue.value did not store.");
        stored = view.Store("path/to/my/asset", "m_customTypeValue.name", customTypeValue.name);
        if (!stored)
            Debug.LogWarning("Property m_customTypeValue.name did not store.");
    }
}
