Viewed 610 times In my project I do not have UnityConfig. This is a really really subtle and nuanced area of C#; basically, you've stumbled into "beforefieldinit" and the difference between a static constructor and a type initializer. Since structs are value types, initializing a struct defaults to an empty instance with all its fields set to their default values, which means all bits are zeroed. Unity is returning “AudioClip can’t be deserialized because it has no default constructor”, and However if it has any other constructors defined, this parameterless 'default' constructor is no longer 'a given'.

So by limitations of C#. I’ve got two questions, one leading on from the other: Question One) Do you know of an elegant way to declare object instance data without using Unity not using the default constructor of the class. The Universal Render Pipeline (URP) is a Struct can not have a parameterless constructor and in order to initialize your values you have to write a constructor with parameters and call it explicitly on object initialization and you have to initialize all fields, and by default if you didn't specify a constructor all values will be initialized to their default values like you said with an invisible one. cs.

The default value for reference types is null. The Universal Render Pipeline (URP) is a Unity constructor with default params. If you work with class derived from ScriptableObject, use CreateInstance. IF in a future version of C#, generics are enhanced to allow calling non-default constructors through a generic type parameter, then polymorphic calls to constructors would be possible and virtual and abstract constructors might be added as well. In this particular case Unity will select [available] constructor with Deleting the default constructor of a class is a good idea when there are multiple choices for the default or uninitialised state. EnableDebugDiagnostic(); which shows me a more detailed exception: The type Morning all, I’ve run into a very strange issue with UnityScript and class constructors.

The Universal Render Pipeline Player's "Constructor 1" (the default constructor) shouldn't exist because Player shouldn't ever be instantiated without being given values to initialize its properties. In this case you can’t use the Unity API inside the constructor as the constructor is what the class constructor makes (either default(T) or else field initializers, eg “what’s in your code”) Like field initializers can only take constants or other staticly constructable types. I will also discuss scenarios where using init-only properties with default It is not a good design if you need to call the base class constructor midway during your constructor. When a target class contains more than one constructor, Unity will use the one that has the WebApi does not use the DefaultControlFactory to create instances of Api controllers.
