Declaring Delegates with Multiplayer class

Development Programming & Scripting Multiplayer & Networking

So I figured out why it wasn’t working before (Please Correct me if I’m wrong).

“FOnlineSessionSearchResults” is not a BlueprintType, so if you try to make a delegate that will be accessed in Blueprints it will fail and give that error. To expose this class to Blueprints you have to use a wrapper struct called “FBlueprintSessionResult” which is a BlueprintType.

I don’t know if this is the only network struct that does this, I’ll update if I find any others.

Updated Code:

DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnSearchComplete , FBlueprintSessionResult, SearchResults)
 
 UCLASS()
 class BOTIBIKEYNOTEDISPLAY_API UBotIBIDisplayGameInstance : public UGameInstance
 {
     GENERATED_BODY()
 
     UPROPERTY(BlueprintAssignable)
 FOnSearchComplete OnSessionSeachComplete;
 
   void OnFindSessionComplete(bool bWasSuccessful)
   {
      FBlueprintSessionResult searchResults = FBlueprintSessionResult();
	 searchResults.OnlineResult = SessionsSearch->SearchResults[0];
     OnSessionSeachComplete.Broadcast(searchResults );
  }
