从 Pygame 中的地图收集硬币

Question

我正在尝试制作 pygame 游戏，但遇到了问题。我希望当角色收集硬币时，分数会改变一，硬币会消失。我还希望硬币出现在玩家周围的随机位置。 我已经尝试了一周了，但我仍然不知道该怎么做，而且我的时间很短：/

有什么帮助吗？

这是我的代码：

import pygame
import sys
from pygame import mixer
import random

pygame.init()


display = pygame.display.set_mode((1280, 720))
clock = pygame.time.Clock()


pygame.display.set_caption("Testowa nazwa bez pomysłu :/")
program_ico = pygame.image.load("icon.jpg")
pygame.display.set_icon(program_ico)

mixer.music.load('music.mp3')
mixer.music.play(-1)

bg = pygame.image.load('bg3.png')


player_walk_images = [pygame.image.load("pp1.png"), pygame.image.load("pp2.png"), pygame.image.load("pp3.png"), pygame.image.load("pp4.png")]
player_walk_up = [pygame.image.load("pb1.png"), pygame.image.load("pb2.png"), pygame.image.load("pb3.png"), pygame.image.load("pb4.png")]
player_walk_down = [pygame.image.load("pf1.png"), pygame.image.load("pf2.png"), pygame.image.load("pf3.png"), pygame.image.load("pf4.png")]
player_stay = [pygame.image.load("ps1.png"),pygame.image.load("ps2.png"),pygame.image.load("ps3.png"),pygame.image.load("ps4.png")]

txt_coin = [pygame.image.load("coin1.png"),pygame.image.load("coin2.png"),pygame.image.load("coin3.png"),pygame.image.load("coin4.png"),pygame.image.load("coin5.png"),pygame.image.load("coin6.png"),pygame.image.load("coin7.png"),pygame.image.load("coin8.png"),pygame.image.load("coin9.png"),pygame.image.load("coin10.png"),pygame.image.load("coin11.png"),pygame.image.load("coin12.png"),pygame.image.load("coin13.png"),pygame.image.load("coin14.png"),pygame.image.load("coin15.png"),pygame.image.load("coin16.png"),pygame.image.load("coin17.png"),pygame.image.load("coin18.png"),pygame.image.load("coin19.png"),pygame.image.load("coin20.png"),pygame.image.load("coin21.png")]

大多数情况下，当我尝试解决方案时，程序没有显示任何错误，并且硬币在任何地方都看不到：//

如果您需要其他资源（例如纹理），请写

Answer 1

所以基本上你可以做一个 def 来检查你是否靠近硬币，如下所示：

collected = False
def collectCheck(x2, x1, y2, y1):
global collected
distance = math.sqrt(math.pow(x2 - x1, 2) + (math.pow(y2 - y1, 2)))
    
# if the distance is smaller than the distance u set then the apple is collected
if distance < 70:
    return True
else:
    return False

然后你可以做一个 if 语句来检查它是否为真然后增加点并删除硬币

score = 1
if collected:
        score += 1
        display.blit('image you want', (random coords that is out of the screen))

最后制作一个随机坐标对于你的硬币，你可以这样做：

coinX = random.randint(0, screen width)
coinY = random.randint(0, screen height)
