pygame-python 中的碰撞检测

Question

import pygame
import sys
from time import sleep
class Doodlejump:
    def __init__(self):
        self.go = True
        self.x = 275
        self.y = 800
        self.doodle = Doodle(self.x, self.y, "doodle_resized.png")
        self.gravity = 7.5
        self.jump_counter = 0
        self.speed = 2
        self.jump_timer = 0

    def run(self):
        pygame.init()
        pygame.display.set_caption("Doodlejump")
        clock = pygame.time.Clock()
        screen = pygame.display.set_mode((600, 800))

        while self.go:
            if self.x < 0:
                self.x = 0
            elif self.x >= 600 - self.doodle.width:
                self.x = 600 - self.doodle.width

            if self.y < 0:
                self.y = 0
            elif self.y >= 800 - self.doodle.height:
                self.y = 800 - self.doodle.height

            if self.y >= 800 - self.doodle.height:
                self.jump_counter = 0

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

            pressed = pygame.key.get_pressed()
            if pressed[pygame.K_LEFT]:
                self.x -= self.speed
            if pressed[pygame.K_RIGHT]:
                self.x += self.speed

            screen.fill((255, 255, 255))

            is_jumping = False
            if pressed[pygame.K_SPACE] and not is_jumping and self.jump_counter < 1 and self.jump_timer <= 0:
                is_jumping = True
                self.y -= self.speed
                self.jump_counter += 1
                self.jump_timer = 100


            if self.jump_timer > 0:
                self.jump_timer -= 1

            jump_speed_factor = 250
            if is_jumping:
                self.y -= jump_speed_factor
                jump_speed_factor *= 0.3
            else:
                self.y += self.gravity
                self.jump_timer -= 15

            platform = pygame.draw.rect(screen, (0, 0, 0), (100, 700, 150, 30))
            if platform.colliderect(self.doodle):
                print("Kollision!!!")


            screen.blit(self.doodle.image, (self.x, self.y))

            pygame.display.update()
            clock.tick(60)

if __name__ == "__main__":
    game = Doodlejump()
    game.run()

我用 Pygame 编写了一个 Doodlejump 游戏，但不幸的是，我的碰撞检测不起作用。当我尝试将涂鸦放在平台上时，它只是跳过平台。这可能是什么原因？我已经将 if 语句从代码的顶部移动到底部，但这没有什么区别。我是否错误地使用了 .colliderect() 方法？发生碰撞时根本不进入 if 块。

Doodle 是在哪里定义的？ 检查 Doodle 函数，我认为问题出在 Doodle 类上
