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"

Audio player: runtime memory usage optimization

Hello world, its been a while.

I have created a very basic BP based audio player for the BGM Tracks. It utilizes sound cues to select a random track from a list of music tracks.

Looking at the size map alone, its more than i would like it to be and i understand the reason is due to the track references being used in the cue. However, i would prefer not having to load them all to the runtime memory. Rather, just having it load one track at a time to the memory (or 2 at most).

Does anyone know a better & more efficient approach to a bgm player ?

I found a property to enable file "streaming" in audio file details section. Couldn't find any documentation or info reg it except that it used to be an experimental feature. If someone has a link please do share.

On enabling, it streams the sound file during run time instead of prior loading to the memory. The size map is negligible and i am still able to play the sound cue without any apparent issues at this point. Will continue with streaming unless i have a reason for otherwise.

Im quite certain that the feature has zero impact to the packaging size but it does reduce the run time usage dramatically. ;)
