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"

1) If pawn is a body, the PlayerController is a soul of player, it represents player and it sends control calls to the pawn that is currently possessing

2)If you mean without Player Controller object, no... at least without modifying UE4 gameplay framework in UE4 engine. Well you could control pawn with simple key nodes in Level Blueprint and some other classes that accept those, but it's not recommended and player controller will be created anyway

If you mean without Player Controller class then yes you can use standard Player Controller class if this is sufficent.

3)Makes Player Controller automatically possess the pawn on the start, Player Controller also auto possess spawned default pawn if you have one, normally you can manually possess pawn with Possess function/node from Player Controller

4) APlayerController class coded in C++, which you extend with blueprint when you make Player Controller class blueprint

5) Player Controller is made for each player connected, engine creates them automatically on start and if someone connects, in include local players when you call Create Player.

Read about how gameplay framework works in UE4 explaining all those base classes and what they are for here:
