FInstancedStruct

[FInstancedStruct](API\Runtime\CoreUObject\StructUtils\FInstancedStruct) works similarly as instanced UObject* property but is USTRUCTs.

Syntax

USTRUCT (BlueprintType ,  
        Meta=(HasNativeMake="/Script/Engine.BlueprintInstancedStructLibrary.MakeInstancedStruct"))  
struct FInstancedStruct

Remarks

FInstancedStruct works similarly as instanced UObject* property but is USTRUCTs.

Example:

FInstancedStructTest;

TArray TestArray;

Constructors

  Type Name Description
Public function    
Public function  

FInstancedStruct ( const UScriptStruct* InScriptStruct
)

  
Public function   This constructor is explicit to avoid accidentally converting struct views to instanced structs (which would result in costly copy of the struct to be made).
