Playsound
MCCompiled supports the native syntax of the playsound command but also has a convenience method for easily importing audio files and setting them up for use in your projects.
Enabling the Feature
You must have the audiofiles feature enabled. See here on how to enable features. This functionality is not enabled by default because it creates entries in the sound_definitions.json file and copies audio files every compilation.
Using Audio Files
Once the feature is enabled, the playsound command will accept an audio file input of either .wav, .ogg, or .fsb.
Sub-folders
In the example above, the explosion.ogg audio file is located in the subfolder resources. As such, the file will be copied into the subfolder sounds/resources in the output. This rule applies to any file that's relative to the location of the project file.
