我怎样才能让这些粒子在 Pygame 中跳跃

如何解决我怎样才能让这些粒子在 Pygame 中跳跃

我想知道如何让这些粒子跳跃而不是移动 x 和 y 速度 (https://gyazo.com/c8923ec5366a5c110b735ccccb555863)

我怎样才能让他们跳起来然后又回到原来的位置？

这是我到目前为止所写的内容。粒子只在 y 和 x 方向移动，它们看起来根本没有跳跃。

import pygame,random

pygame.init()

window = pygame.display.set_mode((500,500))
pygame.display.set_caption("Particle Test")
class player:
    def __init__(self,x,y,height,width,color):
        self.x = x
        self.y = y
        self.height = height
        self.width = width
        self.color = color
        self.rect = pygame.Rect(x,width)
    def draw(self):
        self.rect.topleft = (self.x,self.y)
        pygame.draw.rect(window,self.color,self.rect)


white = 255,105,200
player1 = player(250,200,50,white)


class particle3:
    def __init__(self,y):
        self.x = x
        self.y = y
        self.x_vel = random.randrange(-10,13)//5
        self.y_vel = random.randrange(-10,-1)//5
        self.lifetime = 0
    def draw(self,window):
        self.lifetime += 1
        if self.lifetime <60:
            self.x -= self.x_vel
            self.y -= self.y_vel
            pygame.draw.circle(window,(127,140,141),(self.x,self.y),10)

        
particles = []  

def redraw():
    window.fill((0,0))

    for particle3 in particles:
        particle3.draw(window)
    

    player1.draw()        
fps = 60
clock = pygame.time.Clock()
run = True
render = True
while run:
    clock.tick(fps)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    if player1.y < 350:
        player1.y += 5
    else:
        if render:
            for x in range(20):
                particles.append( particle3(player1.x,player1.y) )
                render = False
        player1.y = 50

        if player1.y == 50:
            render = True
    redraw()
    pygame.display.update()
    
pygame.quit()
