Моя функция столкновения не работает в Pygame ⇐ Python

[Anonymous]

Проблема в том, как работает столкновение: код работает для столкновения, которое происходит сбоку, но по какой-то причине при движении сверху или снизу ввод со стороны приводит к «перепрыгиванию» на противоположную сторону. блокирует место, куда игрок пытается двигаться, а не обычное плавное движение.

Я попробовал поменять порядок операторов if, и в результате поменялась ось, на которой возникла проблема.
Это функция вызывает проблемы:
#Draw a rectangle - diagonal collision on top not working
def drawrectangle(x,y,colour,xscale,yscale):
global screen,dude_x,dude_y,dude_vel_x,dude_vel_y
pygame.draw.rect(screen,(colour), (x,y,100*xscale,100*yscale))
#Check if y is correct before limiting x axis movement
if dude_y + dude.get_rect().height > y and dude_y < y + 100*yscale:
if(dude_x + dude.get_rect().width > x) and (dude_x < x + 100*xscale) :
if dude_vel_x > 0:
dude_x = x - dude.get_rect().width
elif dude_vel_x < 0:
dude_x = x + 100*xscale
#Check if x is correct before limiting y axis movement
if dude_x + dude.get_rect().width > x and dude_x < x + 100*xscale:
