当我运行应该让玩家看着鼠标的代码时，他会发疯

Question

我的播放器有以下代码

class Player(pygame.sprite.Sprite):
def __init__(self, game):
    self.game = game

    self.path = os.path.dirname(__file__)
    self.imageFolder = os.path.join(self.path, "images")

    pygame.sprite.Sprite.__init__(self)
    self.image = pygame.image.load(os.path.join(self.imageFolder, "player.png")).convert_alpha()
    self.rect = self.image.get_rect()
    self.rect.center = (600, 500)
    self.pos = (600,500)

def update(self):
    self.pos = pygame.math.Vector2(self.rect.x, self.rect.y)

    if self.rect.y >= 940:
        self.rect.y = 940

    if self.rect.y <= 10:
        self.rect.y = 10

    if self.rect.x >= 1140:
        self.rect.x = 1140

    if self.rect.x <= 10:
        self.rect.x = 10

    keyPressed = pygame.key.get_pressed()
    if keyPressed[pygame.K_w]:
        self.rect.y -= 5
    if keyPressed[pygame.K_s]:
        self.rect.y += 5
    if keyPressed[pygame.K_d]:
        self.rect.x += 5
    if keyPressed[pygame.K_a]:
        self.rect.x -= 5

    self.lookAtMouse()

def lookAtMouse(self):

    relX, relY = self.game.mouseX - self.rect.x, self.game.mouseY - self.rect.y
    angle = (180 / math.pi) * -math.atan2(relY, relX)

    self.newImage = pygame.transform.rotate(self.image, int(angle))
    self.rect = self.newImage.get_rect()
    self.rect.center = self.pos

当我运行它时，播放器失去控制并沿对角线向屏幕边缘移动。 当我玩 rect 的中心时会发生这种情况。 我无法让玩家轮换，并希望得到帮助，提前感谢您。

如果我保持原始图像的center ，代码对我有用

self.pos = pygame.math.Vector2(self.rect.centerx, self.rect.centery)

用于测试的代码：

我把原始图像中self.original_image和创建旋转的图像self.image

import pygame
import random
import os
import math

# --- constants --- (UPPER_CASE_NAMES)

SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600

FPS = 25 # for more than 220 it has no time to update screen

BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# --- classes --- (CamelCaseNames)


class Player(pygame.sprite.Sprite):
    def __init__(self, game):
        self.game = game

        self.path = os.path.dirname(__file__)
        self.imageFolder = os.path.join(self.path, "images")

        pygame.sprite.Sprite.__init__(self)

        self.original_image = pygame.image.load(os.path.join(self.imageFolder, "player.png")).convert_alpha()
        #self.original_image = pygame.image.load("image.png")).convert_alpha()

        self.image = self.original_image.copy()
        self.rect = self.image.get_rect()
        self.rect.center = (600, 500)
        self.pos = (600,500)

    def update(self):

        if self.rect.y >= 940:
            self.rect.y = 940

        if self.rect.y <= 10:
            self.rect.y = 10

        if self.rect.x >= 1140:
            self.rect.x = 1140

        if self.rect.x <= 10:
            self.rect.x = 10

        keyPressed = pygame.key.get_pressed()
        if keyPressed[pygame.K_w]:
            self.rect.y -= 5
        if keyPressed[pygame.K_s]:

        self.pos = pygame.math.Vector2(self.rect.centerx, self.rect.centery)

        self.lookAtMouse()

    def lookAtMouse(self):
        mouseX, mouseY = pygame.mouse.get_pos()
        relX, relY = mouseX - self.rect.x, mouseY - self.rect.y
        angle = (180 / math.pi) * -math.atan2(relY, relX)

        self.image = pygame.transform.rotate(self.original_image, int(angle))
        self.rect = self.image.get_rect()
        self.rect.center = self.pos
