如果你已经阅读了本系列的前几篇文章，那么你已经了解了编写游戏的所有基础知识。现在你可以在这些基础上，创造一个全功能的游戏。当你第一次学习时，遵循本系列代码示例，这样的“用例”是有帮助的，但是，用例也会约束你。现在是时候运用你学到的知识，以新的方式应用它们了。
|
||||
|
||||
如果说，说起来容易做起来难，这篇文章展示了一个如何将你已经了解的内容用于新目的的例子中。具体来说，就是它涵盖了如何使用你以前的课程中已经了解到的来实现奖励系统。
|
||||
|
||||
在大多数电子游戏中，你有机会在游戏世界中获得“奖励”或收集到宝物和其他物品。奖励通常会增加你的分数或者你的健康指数，或者为你的下一次任务提供信息。

|
||||
|
||||
游戏中包含的奖励类似于编程平台。像平台一样，奖励没有用户控制，随着游戏世界的滚动进行，并且必须检查与玩家的碰撞。
|
||||
|
||||
### 创建奖励函数
|
||||
|
||||
奖励和平台非常相似，你甚至不需要奖励类。您可以重用 **Platform** 类，并将结果称为奖励。

奖励和平台非常相似，你甚至不需要一个奖励的类。你可以重用 `Platform` 类，并将结果称为“奖励”。
|
||||
|
||||
由于奖励类型和位置可能因关卡不同而不同，如果你还没有一个新的功能，请在你的 **Level** 中创建一个名为 **Level** 的新功能。因为奖励物品不是平台，你也必须创建一个新的 **loot_list** 组，然后添加奖励物品。与平台、地面和敌人一样，该组用于检查玩家碰撞:

由于奖励类型和位置可能因关卡不同而不同，如果你还没有，请在你的 `Level` 中创建一个名为 `loot` 的新函数。因为奖励物品不是平台，你也必须创建一个新的 `loot_list` 组，然后添加奖励物品。与平台、地面和敌人一样，该组用于检查玩家碰撞:
|
||||
|
||||
```
|

def loot(lvl,lloc):
|
||||
if lvl == 1:
|
||||
loot_list = pygame.sprite.Group()
|
||||
loot = Platform(300,ty*7,tx,ty, 'loot_1.png')
|
||||
loot_list.add(loot)
|
||||
def loot(lvl,lloc):
|
||||
if lvl == 1:
|
||||
loot_list = pygame.sprite.Group()
|
||||
loot = Platform(300,ty*7,tx,ty, 'loot_1.png')
|
||||
loot_list.add(loot)

if lvl == 2:
|

|
||||
return loot_list
|

```
|
||||
|
||||
你可以随意添加任意数量的奖励对象；记住把每一个都加到你的奖励清单上。***Platform** 类的参数是奖励图标的X位置、Y位置、宽度和高度(通常最容易让你的奖励图标保持和所有其他方块一样的大小)，以及你想要用作的奖励图标。奖励的放置可以和贴图平台一样复杂，所以使用创建关卡时需要创建关卡设计文档。

### 检测碰撞
|
||||
|
||||
就像平台和敌人一样，你可以检查奖励物品和玩家之间的碰撞。逻辑与其他碰撞相同，除了撞击不会(必然)影响重力或健康。取而代之的是，命中会导致奖励物品会消失并增加玩家的分数。

当你的玩家触摸到一个奖励对象时，你可以从 **奖励列表** 中移除该对象。这意味着当你的主循环在 **loot_list** 中重绘所有奖励物品时，它不会重绘那个特定的对象，所以看起来玩家已经获得了奖励物品。

如你所见，你已经掌握了所有的基本知识。你现在要做的就是用新的方式使用你所知道的。
|

|

在下一篇文章中还有一些提示，但是与此同时，用你学到的知识来制作一些简单的单层游戏。限制你试图创造的东西的范围是很重要的，这样你就不会埋没自己。这也使得最终的成品看起来和感觉上更容易完成。
