Pygame 如何让 Sprite 面对鼠标

如何解决Pygame 如何让 Sprite 面对鼠标

我对编程很陌生，我设法编写了一些可以运行的代码

目前，我有一个 500,500 的游戏区，里面有一个精灵，它是一个从图片左上角射出子弹的军人，我希望他在屏幕上不断跟随我的鼠标光标，但这就是我的地方卡住了。

我曾尝试将其他人的代码分割成我的代码，但要么不起作用，要么我没有对其进行足够的更改，要么我对其进行了过多的更改

我听说我需要建立一个向量，但 IDK 如何

这是我的代码很抱歉，如果它一团糟

import pygame
pygame.init()
import math
clock = pygame.time.Clock()
still=pygame.image.load('pngs/pr1.png')
display = pygame.display.set_mode((500,500))

class player_object(object):
    def __init__(self,x,y,radius,height):
        self.x = x
        self.y = y
        self.radius = radius
        self.height = height
        self.vel = 5

        
    def draw(self,display):
        display.blit(still,(self.x,self.y))

class bullet(object):
    def __init__(self,mouse_x,mouse_y):
        self.x = x
        self.y = y
        self.mouse_x = mouse_x
        self.mouse_y = mouse_y
        self.lifetime = 50
        self.speed = 15
        self.angle = math.atan2(mouse_y-self.y,mouse_x-self.x)
        self.x_vel = math.cos(self.angle) * self.speed
        self.y_vel = math.sin(self.angle) * self.speed
        self.radius = 5
 
    def draw(self,draw):
        self.x += int(self.x_vel)
        self.y += int(self.y_vel)

        pygame.draw.circle(display,(0,0),self.y),self.radius)
        self.lifetime -= 1

class enemy_object(object):
    def __init__(self,radius):
        self.x = x
        self.y = y
        self.radius = radius

    def draw(self,display):
        pygame.draw.circle(display,255,self.radius)
        
player = player_object(100,100,50,30)

bullets = []

enemy = enemy_object(400,400,20)

run = True
while run:
    display.fill((255,255))

    x,y = pygame.mouse.get_pos()


    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
            run = False

        if event.type == pygame.MOUSEBUTTONDOWN:
            if event.button == 1:
                bullets.append(bullet(player.x,player.y,y))
   
    

    keys = pygame.key.get_pressed()

    if keys[pygame.K_w] and player.y > player.vel:
        player.y -= 5

    if keys[pygame.K_s] and player.y < 500 - player.height - player.vel:
        player.y += 5

    if keys[pygame.K_a] and player.x > player.vel:
        player.x -= 5

    if keys[pygame.K_d] and player.x < 500 - player.radius - player.vel:
        player.x += 5

    for bullet_ in bullets:
        if bullet_.lifetime <= 0:
            bullets.pop(bullets.index(bullet_))
        bullet_.draw(display)

    player.draw(display)

    enemy.draw(display)
    
    clock.tick(60)
    pygame.display.update()

附言敌人代码是我试图为未来添加敌人

另外，我对游戏的想法是像这样的自上而下的射击游戏 无尽的战争
