KeyboardReleased()

Syntax

Result = KeyboardReleased(KeyID)

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