Pygame，碰撞问题

编程问答 2022-05-14

问题描述

我一直在尝试使用 Pygame 在 Python 中创建一个游戏表单。我在很大程度上遵循了教程，但遇到了麻烦。该游戏是一个简单的平台游戏，我无法添加碰撞。我已经查看了许多其他示例，但似乎无法找到添加 pygame.sprite.collide_rect 命令的位置以及如何让它停止玩家 y 速度以便他停在平台上。任何帮助将不胜感激！谢谢。

代码

import random 
import pygame as pg
pg.init()




icon = pg.image.load("soldier.png")
pg.display.set_icon(icon)
backgroundimage = pg.image.load("background.png")


FPS = 50
Width = 512
Height = 384
Red = (255,0)
#vec = pg.math.Vector2

class platform(pg.sprite.Sprite):
    def __init__(self,x,y):
        pg.sprite.Sprite.__init__(self)
        self.image = pg.image.load("plat.png")
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y



class Player(pg.sprite.Sprite):
    def __init__(self):
        pg.sprite.Sprite.__init__(self)
        self.image = pg.image.load("Spaceman.png")
        self.rect = self.image.get_rect()
        self.rect.center = (Width / 2,Height / 2)
        self.vx = 0
        self.vy = 0
        #self.pos = vec(Width / 2,Height / 2)
        self.acc = 0.2


    def update(self):
        self.vy = self.vy + self.acc
        self.vx = 0
        #self.acc = vec(0,0.5)
        keys = pg.key.get_pressed()
        if keys[pg.K_SPACE]:
            while self.vy > 0:
             self.vy = -5 + self.acc
        if keys[pg.K_LEFT]:
            self.vx = -5
            self.image = pg.image.load("Spaceman2.png")
        if keys[pg.K_RIGHT]:
            self.vx = 5
            self.image = pg.image.load("Spaceman.png")



        self.rect.x += self.vx
        self.rect.y += self.vy
        if self.rect.left > Width:
            self.rect.right = 0
        if self.rect.right < 0:
            self.rect.left = Width
    






class Game:
    def __init__(self):
        pg.init()
        pg.mixer.init()
        self.screen = pg.display.set_mode((Width,Height))
        pg.display.set_caption("OH NOOOO")
        self.clock = pg.time.Clock()
        self.running = True

    def new(self):
        self.all_sprites = pg.sprite.Group()
        self.platforms = pg.sprite.Group()
        self.soldier = pg.sprite.Group()
        self.player = Player()
        self.all_sprites.add(self.player)
        self.soldier.add(self.player)
        p1 = platform(200,200)
        self.all_sprites.add(p1)
        self.platforms.add(p1)
        self.run()


    def run(self):
   
        self.playing = True
        while self.playing:
            self.clock.tick(FPS)
            self.events()
            self.update()
            self.draw()
       

    def update(self):
         self.screen.blit(backgroundimage,[0,0])

         self.all_sprites.update()

    def events(self):
         for event in pg.event.get():
            if event.type == pg.QUIT:
                if self.playing:
                    self.playing = False
                self.running = False

    def draw(self):
        self.all_sprites.draw(self.screen)


        pg.display.flip()
    


    def show_start_screen(self):
        pass


    def show_go_screen(self):
        pass
                  

g = Game()
g.show_start_screen()
while g.running:

    g.new()
    g.show_go_screen()

pg.quit()

这是到目前为止的所有代码，我在这段代码中创建了三个组； all_sprites，soldier 和platforms 但不知道如何让soldier 和platforms 组发生碰撞。非常感谢您的帮助！

解决方法

使用 pygame.sprite.groupcollide() 检测 pygame.sprite.Sprite 对象在 2 个单独的 pygame.sprite.Group 中的碰撞：

if pygame.sprite.groupcollide(self.soldier,self.platforms,False,Fasle):
    print("hit")
