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"

Is this line in the collision tutorial wrong?

So there's a line in this tutorial that doesn't look right: https://docs.unrealengine.com/latest/INT/Programming/Tutorials/Components/5/index.html

Am I missing something? Or is this incorrect? Why is "class" there?

     class UCollidingPawnMovementComponent* OurMovementComponent;
Product Version: UE 4.9

This is correct but optional syntax. You could also write

 UCollidingPawnMovementComponent* OurMovementComponent;

However, putting class in front is not a syntax error. So to answer your question, no, this is not incorrect.

To be more precise, this is called an "elaborated type specifier", you can read about it here : http://en.cppreference.com/w/cpp/language/elaborated_type_specifier

Sometimes it will be necessary for disambiguation, but in your case, I don't think it is (but I would need to see the rest of the code to be sure).

Hope this helps,
