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"

Android 4.19.2 Character Movement Performance

Seems that using around 20 AI controlled skeletal meshes in my android game is severely affecting performance. I use a simple 25,000 tri static mesh as the "floor" with a standard nav mesh spread across. Using the profiler I am seeing the following results per each AI:

The AI uses a simple "Move to" node in blueprints with a random "find radius in navigable zone" number to move some 1000 units about every 4 seconds. Nothing too crazy IMHO.

Can anyone help me understand if these numbers are normal?

Thank you everyone :)

I heard there is a MobileThirdPersonCharacter that has a lighter performance hit. Maybe there is a lighter AI to go with it?

I have not been able to find a very cheap mobile ai move to solution yet.. One thing I saw on another post was to check that your custom mesh does not have more than 4 vertex per bone weights (it's something like that, can't remember the real term) it's an option in most 3d software when doing rigging. I checked this in my case and it didn't help substantially.
