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"

iOS App Crashes due to insufficient memory

Hi there, I am currently developing a mobile app with realistic graphics (something similar to the zen garden app). I am pretty new to UE4 and have been trying to learn on mobile development.

However, I am currently facing memory management problems. The application seems to be crashing after I open and stream 4-6 different levels depending on the size of the levels. Individually, the levels worked fine, but upon loading 1 after another the app crashes.

Below are a few things I have done to help relief in memory management:

  1. I have unload/unstream my levels before I open a new level

  2. I have removed all my UMG at the start of each new level

  3. I have garbage collect at the beginning of each new level

The performance seemed to improve. But crashing issue still happened. The diagnostics have shown to be a jetsam event which I read was a memory management issue.

I am asking if there are any good practices and helpful methods for mobile app optimization?

Thanks in advance.
