UBlueprintInstancedStructLibrary::IsValid_InstancedStruct

function Engine Blueprint Since 5.0

#include "Kismet/BlueprintInstancedStructLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns whether the given InstancedStruct currently holds a valid struct value. Use this as a plain boolean check rather than the exec-pin branch version.

Caveats & Gotchas

• This is the BlueprintPure sibling of IsInstancedStructValid — that one returns an EStructUtilsResult enum wired to exec pins ("Is Valid (Branch)"), this one returns a plain bool for use in expressions and conditionals.
• An InstancedStruct is valid only if it has been initialized with a struct type via InitializeAs or Reset with a non-null StructType; a default-constructed InstancedStruct is not valid.
• Does not verify the contents of the struct are meaningful — only that a struct type has been assigned and memory allocated.

Example

Guard before reading a value C++

if (UBlueprintInstancedStructLibrary::IsValid_InstancedStruct(MyInstancedStruct))
{
    const FMyStruct* Data = MyInstancedStruct.GetPtr<FMyStruct>();
    // use Data
}
