Я делаю эту игру с Pygame, и у меня есть player спрайт, нарисованный с помощью LayeredUpdates. _layer для игрока равно 1, и по какой-то причине, когда он достигает определенной точки по координате y, он просто исчезает. Спрайт ground имеет _layer из 2, поэтому спрайт player всегда должен быть сверху. Странно, что он просто исчезает с определенной координатой y.
