尝试在pygame中创建一个简单的跳转脚本

import pygame
import sys

pygame.init()
width, height = 800, 600
screen = pygame.display.set_mode((width, height))

character_x = 50
character_y = 400
character_y_velocity = 0

ground_height = 50
gravity = 0.5
jump_velocity = -10

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                if character_y == height - ground_height:
                    character_y_velocity = jump_velocity

    character_y_velocity += gravity
    character_y += character_y_velocity

    if character_y > height - ground_height:
        character_y = height - ground_height
        character_y_velocity = 0

    screen.fill((255, 255, 255))  # 清空屏幕
    pygame.draw.rect(screen, (0, 0, 255), (character_x, character_y, 50, 50))  # 绘制角色矩形
    pygame.draw.rect(screen, (0, 255, 0), (0, height - ground_height, width, ground_height))  # 绘制地面矩形
    pygame.display.update()
