KeyboardReleased()

Syntax

Result = KeyboardReleased(KeyID)

Returns 1 if the specified key has been pushed and released, else it returns 0. This command is very useful for switch key check, like a 'Pause' key in a game (one time the game is paused, next time it will continue). The command ExamineKeyboard() must be called before this command to update the keyboard state. The keyboard behaviour can be changed with KeyboardMode(). For a full list of KeyID values, look at KeyboardPushed().

Example:

  If InitSprite() And InitKeyboard() And OpenScreen(800,600,16,"")
    Paused = #False
    Repeat
      FlipBuffers()
      
      If StartDrawing(ScreenOutput())
        
        ExamineKeyboard()
        If KeyboardReleased(#PB_Key_P)
          If Paused = #False
            Paused = #True
          Else
            Paused = #False
          EndIf
        EndIf
        
        DrawingMode(0)

        If Paused = #False
          DrawText(20, 20, "Program is running...")
        Else
          DrawText(20, 20, "Program paused...    ")
        EndIf

        StopDrawing()
      EndIf
    Until KeyboardPushed(#PB_Key_Escape)
  EndIf
