Pygame中图像与矩形的碰撞检测？

import pygame
from pygame.locals import *

pygame.init()

# 创建窗口和画布
screen = pygame.display.set_mode((800, 600))
canvas = pygame.Surface((800, 600))

# 加载图像
image = pygame.image.load("image.png")
image_rect = image.get_rect()

# 创建矩形
rect = pygame.Rect(400, 300, 100, 100)

running = True
while running:
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False

    # 绘制画面
    canvas.fill((255, 255, 255))
    canvas.blit(image, image_rect)

    # 进行碰撞检测
    if image_rect.colliderect(rect):
        # 发生碰撞，执行相应逻辑
        print("碰撞发生！")

    # 将画布绘制到窗口
    screen.blit(canvas, (0, 0))
    pygame.display.update()

pygame.quit()
