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"

Forced to re-place an Actor in the Scene to make the changes effective

I wanted to report a very common issue with Unreal Engine... I specificied UE 4.17 but this has been happening since forever.

I created a class deriving from Actor which has a UBoxComponent and two functions OnBoxOverlapBegin() and OnBoxOverlapEnd()

Before these functions could work, I had to dynamically bind them to the BoxComponent

 _box->OnComponentBeginOverlap.AddDynamic(this, &AMyTriggerBox::OnBoxOverlapBegin);

I compiled, but as you can see I forgot to dynamically bind the second function: OnBoxOverlapEnd()

I dragged the C++ class into the scene and started the game.

The OnBoxOverlapEnd() was not triggering, as expected.

So I came back to my code and added the second bind

 _box->OnComponentEndOverlap.AddDynamic(this, &AMyTriggerBox::OnBoxOverlapEnd);

I compiled, ran the game and.... it was not working! Even if I had added the second bind!

I was getting crazy until I read on this forum (through some researches) of someone having the same problem, and solved it by deleting the Actor from the scene and re-placing it.

How can an Engine like this fall into this banality?

Why has it to be like that?

Will it be ever solved?

Product Version: UE 4.17
