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"

Ribbon causing massive lag

Hello everyone.

In my 2D game, I'm attaching a ribbon to my missiles and they are causing a lot of FPS issues. Basically, each missile decreases the FPS by 15/20. Needless to say that this is probably not normal and not a desirable behaviour.

I also use the deactivate function for when my missile explode, just to keep the trail alive for a while. Now, if the trail is not drawn (for testing purposes), the FPS stays at 120, until the deactivate function is called, which also cause the FPS to drop drastically. What is wrong with this function ? What's going on with my ribbons ? :(

Note that I have a very good computer and those tests are all done within the UE4 editor.

Since I'm far from being an expert, is there any information that may help you or tips I should know ?

Thanks !

The lag is only present in the Editor. The finished game has no lag at all, so I guess this is due to uncompressed code and massive debug running in background with power limitation in the Editor.
