我正试图将从敌人死亡中随机丢弃添加到我在Python中制作的游戏，并想知道如何实现它。我想要添加的水滴是盾和健康，盾具有较低的掉落几率。 Drops的主要代码在这里：
import pygame
class HealthDrop(pygame.sprite.Sprite):
def __init__(self, x, y):
self.image = pygame.image.load('images/Sprites/health.png')
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
self.on_ground = False
self.gravity = 0.5
def update(self):
def render(self, surface):
surface.blit(self.image, self.rect)
class ShieldDrop(pygame.sprite.Sprite):
def __init__(self, x, y):
self.image = pygame.image.load('images/Sprites/shield.png')
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
self.on_ground = False
self.gravity = 0.5
def update(self):
def render(self, surface):
surface.blit(self.image, self.rect)
然后主文件的代码在这里：

答案 0 :(得分：1)
你需要编辑它：
def zombie_move(self, zombie_sprite):
for zombie in self.zombies:
for b in self.bullets:
if pygame.sprite.collide_rect(b, zombie):
zombie.health -= 10
self.bullets.remove(b)
if zombie.health <= 0:
self.zombieskilled += 1
self.player.score += 20
#You need some code here (before removing the zombie)
self.zombies.remove(zombie)
break
对不起，我忘记了如何在Python中做到这一点，但逻辑是这样的：代替代码中的注释，添加类似HealthDrop.append(x, y)或ShieldDrop.append(x, y)的内容，其中x和y应该是僵尸的价值（这就是为什么你应该在移除僵尸之前做到这一点）。
如果您想要随机添加import random，请执行以下操作：
percentage = random.randint(1, 100)
if (percentage >= 1) and (percentage < 10)
healthDrop.append(zombie.x, zombie.y)
else
if (percentage >= 10) and (percentage < 20)
shieldDrop.append(zombie.x, zombie.y)
在这个例子中，我为每个“item”设置10％放弃（它们不能同时掉落），它将一个数字从1到100随机化，如果它是1到9的数字，它的healthDrop，如果它是一个数字从10到19它的shieldDrop，随意尝试百分比使你的游戏平衡
另外不要忘记添加碰撞（我看到你已经有一些碰撞代码所以我猜你知道怎么做）。其余代码应该很容易做到（比如提高健康等等。
我很抱歉我不记得python真的很好，但是你可以使用它们类似于子弹类，我希望你有这个想法，如果有什么麻烦你请告诉我，我会帮助更多:)
