python - Pygame 玩家在击中另一个 obj 时跳回落下

Question

我正在制作一个简单的 Pygame 游戏。这是我的代码：

import pygame

def gravity(player_bottom):

    if player_bottom >= 500:
        Player.jumpable = True
        return 500
    else:
        player_bottom += gravity_strength
        return player_bottom


def create_ground(width, height, x ,y):
    rect = pygame.Rect((x, y), (width, height))
    grounds.append(rect)

def draw_grounds(grounds):
    for ground in grounds:
        pygame.draw.rect(screen, (0,0,0), ground)

def collision_ground(grounds):
    collision_tol = 10
    for ground in grounds:
        if Player.hero_rect.colliderect(ground):
            if abs(Player.hero_rect.left - ground.right) < collision_tol:
                Player.hero_rect.left = ground.right
            if abs(Player.hero_rect.right - ground.left) < collision_tol:
                Player.hero_rect.right = ground.left
            if abs(Player.hero_rect.top - ground.bottom) < collision_tol:
                Player.hero_rect.top = ground.bottom
            if abs(Player.hero_rect.bottom - ground.top) < collision_tol:
                Player.hero_rect.bottom = ground.top
        

class player:
    def __init__(self):
        self.jumpable = False
        self.second_jump = False
        self.vel = 3
        self.jump_power = 50
        self.x = 50
        self.y = 10
        self.hero_rect = hero.get_rect(center = (self.x, self.y))

    def draw(self):
        screen.blit(hero, self.hero_rect)
    def jump(self):
        if self.jumpable:
            self.jumpable = False
            self.second_jump = True
            self.hero_rect.y -= self.jump_power
        elif self.second_jump:
            self.second_jump = False
            self.hero_rect.y -= self.jump_power
    def back(self):
        self.hero_rect.x -= self.vel
    def forward(self):
        self.hero_rect.x += self.vel

pygame.init()
screen = pygame.display.set_mode((700, 500))
screen.fill((255,255,255))

# images
hero = pygame.image.load("assets/hero/blue.png").convert_alpha()

# game val
gravity_strength = 1
grounds = []

Player = player()
create_ground(100, 10, 350, 400)
GRAVITY = pygame.USEREVENT
TOUCH_SUR = pygame.USEREVENT + 1
pygame.time.set_timer(GRAVITY, 10)
pygame.time.set_timer(TOUCH_SUR, 1)

clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                Player.jump()
        if event.type == GRAVITY:
            Player.hero_rect.bottom = gravity(int(Player.hero_rect.bottom))
        if event.type == TOUCH_SUR:
            collision_ground(grounds)

    # front back movement
    keys=pygame.key.get_pressed()
    if keys[pygame.K_a]:
        Player.back()
    if keys[pygame.K_d]:
        Player.forward()

    screen.fill((255,255,255))
    Player.draw()
    draw_grounds(grounds)
    pygame.display.update()
    clock.tick(60) 

一切都很好，除了玩家的跳跃，它保持在 Rect 表面上的传送。LZ，请告诉我如何解决这个问题，非常感谢。
