python - Python、敵のスプライトの制御に問題がある

Question

まったくの初心者で、プログラミング全般に不慣れです。pygame を使用して、Python でサイド スクローラー ゲームを作成しようとしています。プレイヤー、敵、土地のスプライト クラス用に 3 つの異なるライブラリを作成しました。プレイヤーが土地クラスのさまざまなオブジェクトと相互作用 (衝突) し、それらを通り抜けることができないように、土地をスプライトにしました。私が抱えている問題は、敵のスプライトが土地のスプライトとも相互作用するようにしたいということです。理想的には、敵のスプライトをポイント "x" から開始し、ランド スプライトと接触するまで動き (-2) を設定し、その時点で方向を反転させたいと考えています。私は考えられるすべてのことを試してきましたが、オンラインでこれを機能させるための解決策を探していましたが、成功しませんでした。それは本当に単純なはずですが、私はそれを機能させることができません。

お時間をいただきありがとうございます。

ここに私のコードがあります:

ランドスプライト :

import pygame

class Object(pygame.sprite.Sprite):
    def __init__(self,image_file):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load(image_file)
        self.rect = self.image.get_rect()

プレイヤースプライト :

import pygame

class Player(pygame.sprite.Sprite):
    change_x = 0
    change_y = 0
    jump_ready = False
    frame_since_collision = 0
    frame_since_jump = 0
    frame = 0
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.images = []
        for i in range(1,9):
            img = pygame.image.load("pit"+str(i)+".png").convert()
            img.set_colorkey((0,0,0))
            self.images.append(img)
        self.image = self.images[0]
        self.rect = self.image.get_rect()

    def changespeed_x(self,x):
        self.change_x = x
    def changespeed_y(self,y):
        self.change_y = y
    def update(self,ground,brick,enemy):
        if self.change_x < 0:
            self.frame += 1
            if self.frame > 3*4:
                self.frame = 0
            self.image = self.images[self.frame//4]
        if self.change_x > 0:
            self.frame += 1
            if self.frame > 3*4:
                self.frame = 0
            self.image = self.images[self.frame//4+4]

        old_x = self.rect.x
        new_x = old_x + self.change_x
        self.rect.x = new_x

        player_health = 5
        hurt = pygame.sprite.spritecollide(self,enemy,False)
        if hurt:
            player_health -= 1
            print(player_health)

        brick_break = pygame.sprite.spritecollide(self,brick,True)
        collide = pygame.sprite.spritecollide(self,ground,False)
        if collide:
            self.rect.x = old_x
        old_y = self.rect.y
        new_y = old_y + self.change_y
        self.rect.y = new_y

        touch_list = pygame.sprite.spritecollide(self,ground,False)

        for ground in touch_list:
            self.rect.y = old_y
            self.rect.x = old_x
            self.change_y = 0
            self.frame_since_collision = 0
        if self.frame_since_collision < 6 and self.frame_since_jump < 6:
            self.frame_since_jump = 100
            self.change_y -= 8
        self.frame_since_collision += 1
        self.frame_since_jump += 1

    def calc_grav(self):
        self.change_y += .35
        if self.rect.y >= 450 and self.change_y >= 0:
            self.change_y = 0
            self.rect.y = 450
            self.frame_since_collision = 0
    def jump(self,blocks):
        self.jump_ready = True
        self.frame_since_jump = 0

これは機能する敵のスプライトです。左にしか移動しません。プレーヤー クラスにあるような衝突コードのバリエーションを試すたびに、スプライトはランド スプライトと衝突したときに停止します。

敵スプライト :

import pygame


class Enemy(pygame.sprite.Sprite):
    def __init__(self,image_file):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load(image_file)
        self.image = self.image.convert()
        self.image.set_colorkey((0,0,0))
        self.rect = self.image.get_rect()

    def update(self,ground):
        change_x = -2
        self.rect.x += change_x
