pygame.sprite.collide_mask与pygame.sprite.spritecollide的区别
时间: 2023-06-01 07:07:59 浏览: 199
pygame.sprite.collide_mask和pygame.sprite.spritecollide都是Pygame中的碰撞检测函数,但是它们的作用对象不同。collide_mask用于检测两个精灵对象的像素级别的碰撞,而spritecollide用于检测一个精灵对象和一个精灵组对象中是否有碰撞。

if pygame.sprite.collide_rect(player_rect, obstacle1_rect)中的player_rect,与obstacle1_rect报错如何处理
如果报错提示 "NameError: name 'player_rect' is not defined" 或者 "NameError: name 'obstacle1_rect' is not defined",那么很可能是这两个变量没有被正确定义。你需要确保在运行这段代码之前,player_rect和obstacle1_rect这两个变量已经被正确定义并且具有正确的值。
如果报错提示 "AttributeError: 'NoneType' object has no attribute 'colliderect'",那么很可能是player_rect或obstacle1_rect中有一个或两个变量的值为None,即没有被正确初始化。你需要检查这两个变量的初始化过程,确保它们被正确地赋值为pygame.Rect类型的对象。
如果报错提示其他错误,你需要仔细查看错误提示信息,以确定具体的错误原因,并针对性地进行调试和修复。

在代码中添加以下代码可以在游戏界面上添加一条分割线:
```python
# 画一条分割线
pygame.draw.line(screen, [0, 0, 0], [0, 240], [640, 240], 5)
```
将其添加在`screen.fill([255,255,255])`之后,完整代码如下:
