[Gambas-user] R: SDL2 : "Channel" Class has not property nor metods...

[Ru Vuott]

Hello Benoît,

gb.sdl2.audio, like gb.sdl.sound, has these Classes (named channel):
- Channel
- Channels

" At present "  by using "gb.sdl2.audio" I can play a file .wav with "Sound" and "Channels" Class:

For example we'll play simultaneously 2 file wav:

*****************************************************
Public Sub Main()

 Dim sn1, sn2 As Sound

' We set how many channels we want to use:
  Channels.Count = 2

'  We set the volume for each channel:
  Channels[0].Volume = 110
  Channels[1].Volume = 90

' We set for each channel a file WAV:
  sn1 = Sound.Load("/path/of/first/.wav")
  sn2 = Sound.Load("/path/of/second/file.wav")

' We play simultaneously those two files wav:
  Channels[0].Play(sn1)
  Channels[1].Play(sn2)

' We need a loop:
  While True
     Wait 0.01
  Wend
 
End

*******************************************************

Well, with that example I used " Channels " in gb.sdl2.audio, and I did not need "Channel" Class.


=== By using "Channel" class in gb.sdl.sound ===
In old "gb.sdl.sound" a " Channel " Class also is active.
I used it like that:

Public Sub Button1_Click()

Dim s As Sound

  Channels[0].Volume = 0.03

  s = New Sound("/path/of/file.wav")

  Channel(Channels[0]).Play(s)

End

====================


 ...If I want to use " Channel " Class in new "gb.sdl2.audio" component, it seems its properties and methods aren't active.
....but, perhaps, in new "gb.sdl2.audio" component we do not need "Channel" Class, because we can use efficiently the " Channels " Class.

 Channel has only dynamic
 methods and properties. Do you know how to use it?
