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"

UE4 play a specific sound without directly imported from a file

hello, I have a problem about importing a sound file, .wav file, to UE browser. The demand is that, when you click the button on the UI of a level, a window then will appeared, which can provide a series of options that are paths, where my audio is saved. So basically, I need to get my audio file from a path , instead of directly importing it to BP or something else. I have looked into many documentations about sound and audio, but I still have no idea of how to design it. I hope to get some help from you, thank you very much.

Product Version: UE 4.11

Are you asking how to import the sound into UE4, or how to hook it up to a button in BP?

It sounds like he's wanting to make it a function of his game/project to be able to browse to disk select a sound from disk, and play it directly.

There is no direct support for that but if you're a programmer you can technically do it. You'd have to load the .wav file yourself, parse it, then create a new USoundWave UObject, then feed the parsed PCM data into the object directly. That USoundWave object can then be saved as an asset I believe... I'm not super familiar with that side of UE4 (creating new UObject/UAssets from user-generated content... where to store it, etc). But I believe it's possible. Then once you have a USoundWave, you can play it through the audio engine using the normal playsound/spawnsound API, etc.

It's certainly not going to be an easy thing and there's no documentation about how to do it.

Thank you for your detail explanations, and by the way, not he, I am a girl.
