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"

Particle System doesn't Deactives after Delay


I created a laser particle.

I am activating and deactivating this via FirstPersonCharacter blueprint.

When player fires his weapon, it is activated and after 0.05 sec, it should be deactivated, but it doesnt. Interestingly when i remove Delay it directly gets deactivated.

Here are blueprint photos. Of course it never shows up since it gets deactivated directly alt text

and when i do this alt text

It never gets deactivated alt text

EDIT: By the way it starts inactive


I changed blueprint like this and it still doesnt deactivates after activation alt text

Maybe this is a bug?

Ok. I found the reason. At UE4 source KismetSystemLibrary.h Delay definition comments

Perform a latent action with a delay (specified in seconds). Calling again while it is counting down will be ignored.

So i had other Delay calls and that was the reason why it was ignored. Dont call another Delay when one is still counting
