弄清楚如何在子弹和敌人之间进行碰撞检测时遇到问题。敌人本身是阶级，但是子弹不是阶级的一部分。我不能使用内置的spritecollide函数，因为我没有使用sprite.Sprite。
我知道我将必须检查对象图像的各个位置，以查看它们是否重叠，但是不确定如何执行此操作。代码如下：
import pygame
import math, random, sys, pygame.mixer, time
from pygame.locals import *
pygame.mixer.pre_init(44100, -16, 2, 2048)
pygame.mixer.init()

#Defining colours

k = pygame.key.get_pressed()
#Window Settings
w = 1280
h = 720
half_w = w /2
half_h = h /2
AREA = w*h
#Initialising the window
display = pygame.display.set_mode((w,h))
pygame.display.set_caption("Cattleman")
Clock = pygame.time.Clock()
FPS = 600
bullets = []
bulletSprite = pygame.image.load("Bullet1R.png").convert_alpha()
bulletSprite = pygame.transform.scale(bulletSprite, (20,10))
shot = pygame.mixer.Sound("pew1.wav")
global scroll
scroll = 0
class Enemy(pygame.sprite.Sprite):
def __init__(self,x,y,img,):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.image.load("Enemy.png").convert_alpha()
self.image = pygame.transform.scale(self.image,(120,120))
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
self.counter = 0
def move(self):
speed = 2
display.blit(self.image,(self.rect.x,self.rect.y))
if self.counter >= 0 and self.counter <= 300: #counter more then 0 but less than distance
self.rect.x += speed + scroll
elif self.counter >= 300 and self.counter <= 600:
self.rect.x += scroll
elif self.counter >= 600 and self.counter <= 900: #counter is greater than distance but less than double the distance.
self.rect.x -= speed - scroll
elif self.counter >= 900 and self.counter <= 1200:
self.rect.x += scroll
else:
self.counter = 0
self.counter += 1

global jump
global jump_offset
if jump:
jump_offset += 6
if jump_offset >= jump_height:

有什么想法吗？
答案 0 :(得分：3)
如果将子弹变成完全成熟的apiVersion: extensions/v1beta1

对象，则可以使用pygame.Rect()。因此...
pygame.Rect.colliderect然后...
# Creating a new bullet
bullets.append(pygame.Rect(X, Y, width, height))
