我正在制作python pygame迷宫游戏。移动可以和移动的墙壁一起工作，但不能和玩家一起工作，因为玩家永远不会逃离屏幕。目前我正在X轴上移动，但是出了问题。当玩家和左边的墙壁碰撞时，它通常不会让它向左移动。但是当向右移动时，它会稍微忽略碰撞而向右移动。
可重现示例：

import pygame
import math
pygame.init()
surface = pygame.display.set_mode((1000,600))
clock = pygame.time.Clock()
surfrect = surface.get_rect()
player=pygame.Rect((0,0), (35,35))
player.center=surfrect.w/2,surfrect.h/2
touched = False
levelR=[]
control=pygame.Rect((0,0), (50,50))
controld=[]
yspeed,xspeed=0,0
for i in range(-1,2):
    oxr=surfrect.w/2-75*3/2
    oyr=surfrect.h/2-75*3/2+75*3*i
    yr,xr=oyr,oxr
    gf=[]
    for y in '#-#n#-#n#-#'.split('n'):
        for x in y:
            if x=='#':
                gf.append(pygame.Rect((xr, yr), (75,75)))
            xr+=75
        yr+=75
        xr=oxr
    levelR.append([gf,pygame.Rect((oxr,oyr),(75*3,75*3))])
while True:
    for ev in pygame.event.get():
        if ev.type == pygame.QUIT:
            pygame.quit()
        elif ev.type == pygame.MOUSEBUTTONDOWN:
            touched = True
        elif ev.type == pygame.MOUSEBUTTONUP:
            touched = False
    surface.fill((0,0,0))
    for sd in levelR:pygame.draw.rect(surface,(35,35,35),sd[1])
    pygame.draw.circle(surface, (200,200,200), player.center, player.width/2-player.width/19, player.width)
    for sd in levelR:
        for rect in sd[0]:
            scale=0.6
            recti=pygame.Rect((rect.x,rect.y), (rect.width*scale,rect.height*scale))
            recti.center=rect.center
            pygame.draw.rect(surface,(255,255,255),rect)
            pygame.draw.rect(surface,(0,0,0),recti)
    if touched and not controld:
        controld=pygame.mouse.get_pos()
        control.center=controld
    elif touched and controld:
        radius = 150
        x,y=pygame.mouse.get_pos()
        distance=math.dist((x, y),controld)
        if distance < radius:
            pos=(x, y)
        else:
            dx=x-controld[0]
            dy=y-controld[1]
            ratio=radius/distance
            pos=controld[0]+ratio*dx, controld[1]+ratio*dy
        control.center=pos
        try:xmd=(x-controld[0])/abs(x-controld[0])
        except:xmd=0
        try:ymd=(y-controld[1])/abs(y-controld[1])
        except:ymd=0
        sr=0.02*(150/radius)
        xspeed=xmd*abs(control.centerx-controld[0])*sr
        yspeed=ymd*abs(control.centery-controld[1])*sr
        collisiont=5
        for sd in levelR:
            for block in sd[0]:
                block.x-=xspeed
            sd[1].x-=xspeed
        for rect in [i for sd in levelR for i in sd[0]]:
            if player.colliderect(rect):
                for sd in levelR:
                    for block in sd[0]:
                        block.x+=xspeed
                    sd[1].x+=xspeed
                break
        pygame.draw.circle(surface, (255,255,255), control.center, control.width,control.width)
        pygame.draw.circle(surface, (255,255,255), controld, radius, 5)
    elif not touched and controld:controld=()
    pygame.display.flip() 
    clock.tick(60)

我试着调试碰撞，发现当与墙壁碰撞时向右移动会阻止玩家向右移动，但玩家会稍微向右移动。
我期望当玩家与墙壁碰撞时墙壁不会移动。
碰巧的是，当玩家撞到墙壁时向右移动并没有直接阻止它。
