Question

我正在尝试做到这一点，以便当我的玩家精灵与敌人碰撞时，该玩家会被杀死。但是，只有当敌人恰巧在与玩家相同的位置生成时，我的玩家才会死亡，而不是在玩家四处走动并故意触摸另一个精灵时死亡。

这是我的代码：


import math
from random import randint
import pygame
from pygame.math import Vector2

pygame.init()

screen = pygame.display.set_mode((600, 600))
screen_width = 600
screen_height = 600
black = (0, 0, 0)
pygame.display.set_caption("gang")
clock = pygame.time.Clock()


class Player(pygame.sprite.Sprite):

    def __init__(self, pos):
        super().__init__()
        self.image = pygame.Surface((50, 30), pygame.SRCALPHA)
        pygame.draw.polygon(self.image, pygame.Color('steelblue2'), [(0, 0), (50, 15), (0, 30)])
        self.original_image = self.image
        self.rect = self.image.get_rect(center=pos)
        self.pos = Vector2(pos)
        self.velocityx = Vector2(6, 0)
        self.velocityy = Vector2(0, 6)

    def update(self):
        self.rect.center = (int(self.pos.x), int(self.pos.y))
        clamp_rect = self.rect.clamp(screen.get_rect())
        if clamp_rect != self.rect:
            self.rect = clamp_rect
            self.pos.x, self.pos.y = self.rect.center
        self.rotate()

    def rotate(self):
        direction = pygame.mouse.get_pos() - self.pos
        radius, angle = direction.as_polar()
        self.image = pygame.transform.rotate(self.original_image, -angle)
        self.rect = self.image.get_rect(center=self.rect.center)


class Enemy(pygame.sprite.Sprite):
    def __init__(self, pos):
        super().__init__()
        self.image = pygame.Surface((50, 50))
        self.image.fill((randint(0, 255), randint(0, 255), randint(0, 255)))
        self.rect = self.image.get_rect(center=pos)
        self.pos = Vector2(pos)
        self.velocity = Vector2(1, 0)

    def update(self):
        self.pos += self.velocity
        self.rect.center = self.pos


class Projectile(pygame.sprite.Sprite):
    def __init__(self, pos):
        super().__init__()
        self.image = pygame.Surface((9, 15), pygame.SRCALPHA)
        pygame.draw.circle(self.image, (0, 0, 0), (30, 50), 14)
        self.rect = self.image.get_rect(center=pos)
        self.pos = Vector2(pos)
        self.velocityx = Vector2(9, 0)
        self.velocityy = Vector2(0, 9)

    def update(self):
        self.pos += self.velocityx
        self.rect.center = self.pos


def draw_window():
    screen.fill((30, 30, 30))
    all_sprites.update()
    all_sprites.draw(screen)
    bullets.update()
    bullets.draw(screen)
    pygame.display.update()


def xor(a, b):
    if bool(a) != bool(b):
        return True
    else:
        return False


def game_end():
    pygame.font.init()
    text = pygame.font.Font('freesansbold.ttf', 32)
    text_surface = text.render('Game Over', False, (255, 255, 255))
    text_rect = text_surface.get_rect()
    text_rect.center = (86, 86)
    screen.blit(text_surface, (172, 172))
    pygame.display.update()


player = Player((300, 300))
projectile = Projectile((150, 150))
bullets = pygame.sprite.Group(projectile)
enemies_list = pygame.sprite.Group()
all_sprites = pygame.sprite.Group(player, projectile)


def collision():
    score = 0

    for i in range(5):
        enemy = Enemy((randint(0, 600), randint(0, 600)))
        enemies_list.add(enemy)
        all_sprites.add(enemy)

        collide_list = pygame.sprite.spritecollide(player, enemies_list, True)
        for enemy in collide_list:
            all_sprites.remove(player)


collision()


def main():
    screen_rect = screen.get_rect()

    run = True
    while run:
        clock.tick(60)

        keys = pygame.key.get_pressed()

        for e in pygame.event.get():
            if e.type == pygame.QUIT:
                run = False

        if keys[pygame.K_SPACE]:
            if len(bullets) < 5:
                projectile.pos += projectile.velocityx
        if xor(keys[pygame.K_a], keys[pygame.K_LEFT]):
            player.pos -= player.velocityx
        elif xor(keys[pygame.K_d], keys[pygame.K_RIGHT]):
            player.pos += player.velocityx
        elif xor(keys[pygame.K_w], keys[pygame.K_UP]):
            player.pos -= player.velocityy
        elif xor(keys[pygame.K_s], keys[pygame.K_DOWN]):
            player.pos += player.velocityy

        player.rect.clamp_ip(screen_rect)

        draw_window()


main()

我如何做到这一点，以便检测到碰撞并因此在两个精灵移动的同时将我的玩家从游戏中移除？

您必须检查玩家是否在主循环中与敌人相撞：

例如

run = True
hit_count = 0
while run:

    # [...]

    player.rect.clamp_ip(screen_rect)

    collidelist = pygame.sprite.spritecollide(player, enemies_list, False)
    if collidelist:
        hit_count += 1
        print("hit", hit_count)

    draw_window()

如果您要查找最初的敌人位置（不在玩家身上），则必须先检查新敌人和玩家的碰撞，然后再将其分别添加到enemies_list {{1} }：

例如

all_sprites
