UObject Instance Creation

NewObject

NewObject() is the simplest UObject factory method. It takes in an optional outer object and class and creates a new instance with an automatically generated name.

	template< class T >
	T* NewObject
	(
		UObject* Outer=(UObject*)GetTransientPackage(),
		UClass* Class=T::StaticClass()
	)
Copy full snippet

template< class T > T* NewObject ( UObject* Outer=(UObject*)GetTransientPackage(), UClass* Class=T::StaticClass() )

NewNamedObject

NewNamedObject() expands on NewObject() by allowing a name for the new instance as well as Object Flags and a template object to be specified as an argument.

	template< class TClass >
	TClass* NewNamedObject
	(
		UObject* Outer,
		FName Name,
		EObjectFlags Flags = RF_NoFlags,
		UObject const* Template=NULL
	)
Copy full snippet

template< class TClass > TClass* NewNamedObject ( UObject* Outer, FName Name, EObjectFlags Flags = RF_NoFlags, UObject const* Template=NULL )

ConstructObject

For complete flexibility, new instances of UObjects can be created using the ConstructObject() function. This function calls StaticConstructObject(), which allocates the Object, executes the ClassConstructor, and performs any initialization such as loading config properties, loading localized properties, and instancing components.

	template< class T >
	T* ConstructObject
	(
		UClass* Class,
		UObject* Outer = (UObject*)GetTransientPackage(),
		FName Name=NAME_None,
		EObjectFlags SetFlags=RF_NoFlags,
		UObject const* Template=NULL,
		bool bCopyTransientsFromClassDefaults=false,
		struct FObjectInstancingGraph* InstanceGraph=NULL
	)
Copy full snippet

template< class T > T* ConstructObject ( UClass* Class, UObject* Outer = (UObject*)GetTransientPackage(), FName Name=NAME_None, EObjectFlags SetFlags=RF_NoFlags, UObject const* Template=NULL, bool bCopyTransientsFromClassDefaults=false, struct FObjectInstancingGraph* InstanceGraph=NULL )

Object Flags

The EObjectFlags enumeration is used to quickly and succinctly describe an Object. There are various flags to describe the type of Object, how it is handled by garbage collection, the stage the Object is at in its lifetime, etc. There are also special all or none masks and predefined groups of flags.
