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] Applying Low Pass Filter to audio

I need to attach a LPF (Low Pass Filter) to some audio (Music-2D) only when the game is paused. I've tried very different set-ups only to come up short and it's becoming very time consuming.

Has anyone managed to pull this off or something similar?

I have the same issue. Although LowPassFilter bool on/off and float frequency can be changed in runtime it doesn't work on sound. Apparently it works only when setup before running a game.

I have the same issue. Want to apply a dynamic low pass filter to a sword swinging sound effect. Soundmix doesn't cut it since I can't change the frequency values during runtime.
