Вопрос:
Я пытаюсь заставить прямоугольник оставаться на движущейся линии. Я слышал, что мне нужно будет заставить прямоугольник двигаться с той же скоростью, что и линия. Но я немного завинчиваю скорость, поэтому, если кто-нибудь знает, как я бы исправил скорость.

Ответ №1:
Сначала вам нужно вычислить y-перемещение игрока:
move_y = 2
if hoppa==True:
hoppteljari =1
if hoppteljari < 20:
move_y = -2
elif hoppteljari>20 and hoppteljari<24:
move_y = 0
elif hoppteljari>24:
move_y = 1
Вы должны найти y-расстояние ( dy_platform ) до следующей платформы под вами:
dy_platform = math.inf
for i in range (0,fjx):
if x_veggur[i][0] <= x kassi_staerd and x <= x_veggur[i][2]:
line_top = x_veggur[i][1]
player_bottom = (y kassi_staerd)
dy = line_top - player_bottom
if -0.001 <= dy < dy_platform:
dy_platform = dy
Если расстояние меньше суммы движения платформы вверх и скорости падения игрока, вычислите новую позицию игрока в зависимости от y-положения платформы:
if dy_platform - move_y x_veggur_speed <= 0:
y = y dy_platform x_veggur_speed
hoppa=False
hoppteljari=0
else:
y = move_y
