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"

Player Controllers are never the same object between server and client, even if it represents the same player. At least not in my experience, so unless you're getting weird behavior this is probably okay.

Even though they are different objects they have the same connection via the Player though, which is why RPCs work through player controller and actually hit the correct player controller object on both sides.

I may have this wrong but when i treat it that way my network game works properly.

And what i need to do? I need that the server and the client can drive on the same car.

The possession happens (Possess event) only on the server so it doesn't matter if the controller objects are different. They are replicated so even if the names differ the values are kept synchronized by the engine.

The server should automatically notify the client controller that the player pawn is changed and the above scheme should work.

Is there a specific problem coming out of this?

You're casting self (Character) to a player controller which is totally different, instead of self GetPlayerController > Cast to >> MyPlayerController.

Thanks, it fix the warning, but how to fix the error?

Get Game Mode > Cast to ThirdPersonGameMode > the result of the cast is the target in your event with the error.
