cant use my delegate in BP

Development Programming & Scripting C++

You could do this:

Test.h


...
#include "Test.generated.h"

DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FMyCustomOnCreatePartyComplete, ...);
//DECLARE_DELEGATE_OneParam(FMyCustomOnCreatePartyComplete, ..); <- This is causing error but I don't know why.


UCLASS()
class ATest : public AActor
{
    ...

public:
    UPROPERTY(BlueprintAssignable)
    FMyCustomOnCreatePartyComplete OnCreatePartyComplete;

    ...
}

For some reason DECLARE_DELEGATE_* is causing the error you posted:


error : Unrecognized type 'FOnCreatePartyComplete' - type must be a UCLASS, USTRUCT or UENUM

I would use my own delegate to expose to Blueprint, as you wouldn’t have much trouble if Unreal changes or deprecate the delegate you are trying to use. I had this problem once.
Just Broadcast your own delegate when FOnCreatePartyComplete is called.
