Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Need help with FScriptArray and filling it with TArray data

0

I am trying to load data from a file into a blueprint TArray variable. I dont know how to cast the TArray to FScriptArray correctly or is that the issue?

 bool UCronoGameDataHelper::SetBoolArrayByName(UObject * target, FName varName, TArray<bool> newVar)
     {
         UArrayProperty* arrayProp = FindField<UArrayProperty>(target->GetClass(), varName);
     
         if (arrayProp && arrayProp->Inner->IsA<UBoolProperty>())
         {
             const FScriptArray& sArray = (const FScriptArray&)newVar;
             // TODO: Cast does not work?
             arrayProp->SetPropertyValue_InContainer(target, sArray); // This is causing an error
             return true;
         }
         // TODO: Add logging
         return false;
     }

When arrayProp->SetPropertyValue_InContainer(target, sArray); is called I get void operator=(const FScriptArray&) { check(false); } failing from ScriptsArray.h
