在Pygame中从地图上收集硬币

Question

我正试图制作一款pygame游戏，但遇到了问题。我希望当一个角色收集到一枚硬币时，分数会改变一，硬币就会消失。我也希望硬币出现在玩家周围的随机位置。我已经试了一个星期了，但我仍然不知道怎么做，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")]

希望得到的快速帮助

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，硬币在任何地方都看不到：//

如果你需要其他资源，如纹理，请写

Answer 1

所以基本上你可以做一个def来检查你是否接近硬币，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语句来检查它是否是真的，然后增加点数并移除硬币

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

最后，为你的硬币制作一个随机坐标，你可以这样做：

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