It works but it is not what I wanted. I will explain myself better:
Being an event "every x seconds" means that it alternates the movement every x seconds from horizontal to vertical, and vertical to horizontal.
At the beginning I said about the "compare time" event in 15 seconds,
because I wanted when the player plays from the second 0 to the 14 had pipes with their default movement (horizontal). Then, when he reached the second 15 in the game, the pipes get the vertical movement permanently. Finally, when he's 30 seconds, the pipes get Angle movement permanently, and maybe a new movement on the 45, 60...
This, would give a feeling that the player is advancing between levels, but in reality it will be forever in the same layout.
