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"

Blueprint simulation bug

Hello, I'm trying to do things with UE4 just for a second day, so maybe it's not a bug, but a feature )) but anyway:

1) Add blueprint to some actor

2) In the blueprint designer add On Click event to the actor

3) Add 2 instances of the "blueprint" to the scene

4) Press the "Play" button and try to click those instances while watching at the blueprint's simulation window.

Result: the events ere firing as they should, but the simulation window says that the event is firing only for the first instance of the blueprint. I know that events are firing at both instances, because i have used the "Print String" method for the OnClick event. So... "Hello" string was printed no matter what instance i click, but the sumulation was shown only for the first instance.

It's a bit confusing for beginners...

Hey Naivrat,

This isn't a bug. What's happening is that the Blueprint Editor window that you have open is only tracking one instance of that Blueprint at a time. To switch between them, look in the toolbar for the Debug Filter. While Playing, you can select which instance you want to watch.

Hope that helps!

Thank you for the answer! As I have hoped this was a feature :) Maybe this information should be added to the user manual (the getting started section), beacuse it's a bit confusing for beginners like me.

We have some documentation on it here, if you'd like:


I think the docs team likes to keep the Getting Started sections to absolute essentials, and debugging is something slightly more advanced.

I'm Senior Software Engineer myself, isn't the debugging process about main part of programming? Things rarely work as you want, but usually things work as you have coded them to :) But, I agree, for a real beginner the "Getting Started" section should be as clear as possible.
