我做了一个简单的平台游戏，我想学习如何制作基本的收集硬币系统 在我的平台上产生硬币的地方，当我消费时，我可以通过点数系统获得点数 这是我的比赛票价：Game 我已经在youtube上查看了如何执行此操作，但没有任何教程对此进行了介绍，但我发现了1，但他们并没有解释我如何执行此操作， 和我的脚本：

答案 0 :(得分：2)
if playerman.rect.colliderect(coin.rect):，如果它碰撞了，将其加到分数上并从列表中删除，您可以使用del Coin_list[coin_index]来删除硬币（硬币索引是列表中关于数字的位置）是）。
先尝试一下，向我们展示您的尝试，我们将为您提供帮助
太好了，看起来还不错，我只能看到2个问题，
1）您需要使用滚动条移动硬币，这很容易，与敌人相同，但是带有硬币，请让我们这样做
2）对于碰撞，您与敌人的行为相同，如果发生碰撞，请在顶部移动，这不是您想要的，您希望它消失并通过它
对于碰撞，您必须使用一种先进的技术，即向后循环硬币
for i in range(len(Coins_list)-1,-1,-1):
if playerman.rect.colliderect(coin.rect):
del Coins_list[i]
score += 1
这是因为当您从列表中删除某项内容时，所有内容都会向下移动以填充它，例如如果删除第3个元素，则第4个元素现在变为第3个元素。因此，如果您遍历所有这些元素，并且删除了第3个，则当您移至第4个时，实际上是第5个，因为第4个移至第3个。因此，您最终跳过了一个，并且由于尝试获取最后一个减少了一个的元素而收到索引错误。因此，向后表示如果删除一个，则已经检查的对象将被移动，而hvanet的对象将保持不变。
对于文本，请使用变量score（如上）并将其设置为0。文本被硬编码为0，因此您希望它是得分，因此它被更改了
score = 0
text = font.render('Score = ' + str(score), True, NiceOlive)
textRect = text.get_rect()
textRect.center = (100, 40)
我还将此添加到了score+= 1
现在您可能会注意到硬币并没有消失，这是因为您单独绘制它们，只想在列表中绘制它们就可以绘制
window.fill((0,0,0))
window.blit(text,textRect)
for coin in Coins_list:
coin.draw()
playerman.draw()
for enemey in enemies:
enemy.draw()
