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"

Unable to cast from parent class to child class BP's

Hey, I am currently trying to use certain BP's and have to use a cast more specifically this is a cast from parent class to a child class but the cast fails. I am posting certain images which might be able to help with the problem for more clarity i am trying to attain something like this :

 class A
 {
     public :
     A(){}
       void print()
     {
         cout<<"A Here";
     }
 };
 
 class B :public A
 {
     B():A(){}
     public :
     void print()
     {
         cout<<"B Here";
     }
 };
 int main() {
 A* a = new A();
 B* b = (B*)a;
 b->print();
 
 }

This works fine in c++ but i am having issue's with BP's Here's some picture's for reference. alt text

MyAIController is a child of AIController, right? Are you sure that the Controller is not pending kill or something, so that GetController->IsValid is true?
