IPropertyDatabaseView.IsPersistableType

参数

返回值

bool 如果该类型可以在文件中持久化，则为 True，否则为 False。

描述

返回一个布尔值，指示是否可以将类型持久化到备份文件。

只有某些类型可以持久化到备份文件，以在域重新加载和退出 Unity 时保持存续。但是，任何类型都可以存储在PropertyDatabase中，而无需备份。如果您绝对需要持久化，您可以始终将自定义对象分解成可以持久化的较小属性。

// 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.");
    }
}
