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"

No operator found

Hello guys! Trying to use new nativize blueprints future, and its mostly workst, but one widget doesnt work, so i excluded it from nativization. When i package game i get error -

  error C2678: binary '=': no operator found which takes a left-hand operand of type 'const FString' (or there is no acceptable conversion)

What can it be? Part of code looks like that

                 if(IsValid(bpv__K2Node_DynamicCast_AsHUD_CLASS__pf) && IsValid(bpv__K2Node_DynamicCast_AsHUD_CLASS__pf->bpv__champ_select__pf))
                     FUnconvertedWrapper__UChamp_Select_C__pf1639646137(bpv__K2Node_DynamicCast_AsHUD_CLASS__pf->bpv__champ_select__pf).GetRef__chat__pf() = bpv__chat__pf;

Any help guys?

Yea, looks like a bug, thank you. Just cant find any bugreports on forum and answerhub about this feature, looks like i am the only one who is trying to use it

Although it looks like you have figured out what causes the issue, could you please provide information on how we can reproduce it in a clean project? Nativizing is currently experimental, so we'd like to ensure that we enter any issues that we are seeing with the feature as bug reports.

Thank you

In my player controller i have onrep_notify variable, when it fires i cast to hud_class, getting widget variable and changing variable in the widget, so it works like controller->hud_class->widget->variable. So the problem was with interaction with widget or/and variable inside widget. Also, after compile i just cant make build works as expected. In player controller i handle player input, then cast to controlled character and do some magic here (have moba game), but when i use any key, that handeled in controller, i get fatall error, logs are clear, dont know what is wrong.
