Issue Tracker: 2296


1 string url
The URL of the sound to play
2 string flags
Flags for the sound. Can be one or more of following, separated by a space (" "):
  • 3d - Makes the sound 3D, so you can set its position
  • mono - Forces the sound to have only one channel
  • noplay - Forces the sound not to play as soon as this function is called
  • noblock - Disables streaming in blocks. It is more resource-intensive, but it is required for IGModAudioChannel:SetTime.

If you don't want to use any of the above, you can just leave it as "".

3 function callback
Callback function that is called as soon as the the stream is loaded. It has the following arguments:
  • IGModAudioChannel soundchannel - The sound channel
  • number errorID - ID of an error, if an error has occured
  • string errorName - Name of an error, if an error has occured


Example usage of the function.

local g_station = nil sound.PlayURL ( "URL", "3d", function( station ) if ( IsValid( station ) ) then station:SetPos( LocalPlayer():GetPos() ) station:Play() -- Keep a reference to the audio object, so it doesn't get garbage collected which will stop the sound g_station = station else LocalPlayer():ChatPrint( "Invalid URL!" ) end end )
