【pygame】虚拟界面的使用Surface及预渲染|动态调整窗口

import pygame

# 初始化 Pygame
pygame.init()

# 定义初始窗口大小
screen_width, screen_height = 800, 600

# 创建可调整大小的窗口
screen = pygame.display.set_mode((screen_width, screen_height), pygame.RESIZABLE)
pygame.display.set_caption("预渲染并缓存静态元素 - 支持窗口调整")

# 定义颜色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)

# 创建一个缓存 Surface，用于预渲染静态元素
def create_cache_surface(width, height):
    cache_surface = pygame.Surface((width, height))
    cache_surface.fill(BLACK)
    pygame.draw.rect(cache_surface, RED, (50, 50, 200, 100))  # 绘制一个红色矩形
    pygame.draw.circle(cache_surface, GREEN, (width // 2, height // 2), 50)  # 绘制一个绿色圆形
    pygame.draw.line(cache_surface, WHITE, (100, 100), (width - 100, height - 100), 5)  # 绘制一条白色线段
    return cache_surface

# 初始创建缓存 Surface
cache_surface = create_cache_surface(screen_width, screen_height)

# 主循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.VIDEORESIZE:
            # 窗口大小改变时，更新窗口尺寸并重新创建缓存 Surface
            screen_width, screen_height = event.size
            screen = pygame.display.set_mode((screen_width, screen_height), pygame.RESIZABLE)
            cache_surface = create_cache_surface(screen_width, screen_height)

    # 每帧直接绘制缓存的 Surface
    screen.blit(cache_surface, (0, 0))

    # 更新屏幕
    pygame.display.flip()

# 退出 Pygame
pygame.quit()
