Error C2679 binary '=': no operator found which takes a right-hand operand of type 'const FVector2D' (or there is no acceptable conversion)
代码
CenterVertex.Position = Center;Position和Center都是FVector2D类型
/**
* A vector in 2-D space composed of components (X, Y) with floating point precision.
* @note The full C++ class is located here: Engine\Source\Runtime\Core\Public\Math\Vector2D.h
*/
USTRUCT(immutable, noexport, BlueprintType, meta=(HasNativeMake="Engine.KismetMathLibrary.MakeVector2D", HasNativeBreak="Engine.KismetMathLibrary.BreakVector2D"))
struct FVector2D
{
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=Vector2D, SaveGame)
FLargeWorldCoordinatesReal X;
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=Vector2D, SaveGame)
FLargeWorldCoordinatesReal Y;
};解决
CenterVertex.Position.X = Center.X;
CenterVertex.Position.Y = Center.Y;原因
目前编译器不支持结构体实例的复制，只能针对结构体的字段，逐一复制
