对于学校项目，我需要通过实现向鼠标位置射击 Kunais/Shurikens 的方式来完成下面的 pygame 程序，以便能够击中敌人的精灵.

我们的游戏会有不同的场景(标题场景、游戏场景、游戏结束场景)，所以现在让我们实现它们:

现在让我们实现核心游戏.首先，我们需要一些精灵，所以让我们创建一个 Actor 类并准备游戏场景以显示和重置我们的精灵.我们使用一些 pygame 的基本内容，例如
是时候采取一些行动了.让我们在我们的演员中实现一些行为.我们创建了我们想要的每种不同行为的功能.一个让托比在屏幕上移动，一个让鸣人通过键盘控制，一个让苦无.
由于我们使用 Vector 类来表示精灵的位置和方向，因此只需进行减法即可使 kunai 向鼠标位置移动.

Can anyone help me out on this ? I know how to get the mouse position but I can't get a class to work properly.

Let's discard everything and start from scratch and make use of pygame features like sprites and vector math.
We begin with a basic skeleton of a pygame game, a simple window:
import pygame
def main():
screen = pygame.display.set_mode((640, 480))
clock = pygame.time.Clock()
while True:
events = pygame.event.get()
for e in events:
if e.type == pygame.QUIT:
return
screen.fill(pygame.Color('grey'))
pygame.display.flip()
clock.tick(60)
if __name__ == '__main__':
main()
Our game will have different scenes (title scene, game scene, game-over scene), so let's implement them now:
import pygame
import pygame.freetype
pygame.init()
FONT = pygame.freetype.SysFont(None, 32)
class SimpleScene:
def __init__(self, text, background, next_scene):
if background:
self.background = pygame.image.load(background).convert()
else:
self.background = pygame.Surface((640, 480))
self.background.fill(pygame.Color('white'))
if text:
FONT.render_to(self.background, (100, 200), text, pygame.Color('black'))
FONT.render_to(self.background, ( 99, 199), text, pygame.Color('red'))
self.next_scene = next_scene
def start(self):
pass
def draw(self, screen):
screen.blit(self.background, (0, 0))
def update(self, events, dt):
for event in events:
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
return self.next_scene
class Game:
def __init__(self):
self.background = pygame.image.load('background.png').convert()
def start(self):
pass
def draw(self, screen):
screen.blit(self.background, (0, 0))
def update(self, events, dt):
for event in events:
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
return 'VICTORY'
def main():
screen = pygame.display.set_mode((640, 480))
clock = pygame.time.Clock()
scenes = {
'TITLE': SimpleScene('PRESS SPACE TO START', 'background.png', 'GAME'),
'GAME': Game(),
'VICTORY': SimpleScene('YOU WIN!', None, 'TITLE'),
'DEFEAT': SimpleScene('YOU LOSE!', None, 'TITLE'),
}
scene = scenes['TITLE']
dt = 0
while True:
events = pygame.event.get()
for e in events:
if e.type == pygame.QUIT:
return
next_scene = scene.update(events, dt)
if next_scene:
scene = scenes[next_scene]
scene.start()
scene.draw(screen)
pygame.display.flip()
dt = clock.tick(60)
if __name__ == '__main__':
main()
This allows us to cycle through the game scenes by pressing space.
Now let's implement the core game. First, we need some sprites, so let's create an Actor class and prepare the game scene to display and reset our sprites. We use some of pygame's basic stuff, like the Sprite class.
...
class Actor(pygame.sprite.Sprite):
def __init__(self, image, pos, direction):
super().__init__()
self.image = image
self.rect = self.image.get_rect(center=pos)
self.pos = pygame.Vector2(*pos)
self.direction = pygame.Vector2(*direction)
class Game:
def __init__(self):
self.background = pygame.image.load('background.png').convert()
self.images = {
'tobi': pygame.image.load('tobi.png').convert_alpha(),
'naruto': pygame.image.load('naruto.png').convert_alpha(),
'kunai': pygame.image.load('kunai.png').convert_alpha()
}
self.sprites = pygame.sprite.Group()
def start(self):
self.sprites.empty()
self.sprites.add(Actor(self.images['naruto'], (50, 150), (0, 0)))
self.sprites.add(Actor(self.images['tobi'], (450, 300), (0, 0)))
def draw(self, screen):
screen.blit(self.background, (0, 0))
self.sprites.draw(screen)
def update(self, events, dt):
for event in events:
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
return 'VICTORY'
self.sprites.update()
...
Time for some action. Let's implement some behaviour in our actors. We create function of each different kind of behaviour we want. One for Tobi to move along the screen, one for Naruto to be controlled by the keyboard, and one for the kunais.
Since we use the Vector class for the position and direction of our sprites, is simply a matter of substraction to make the kunai move towards the mouse position.
Here's the full code:

if self.enemy_lives <= 0:
return 'VICTORY'

def main():
screen = pygame.display.set_mode((640, 480))
clock = pygame.time.Clock()
scenes = {
'TITLE': SimpleScene('PRESS SPACE TO START', 'background.png', 'GAME'),
'GAME': Game(),
'VICTORY': SimpleScene('YOU WIN!', None, 'TITLE'),
'DEFEAT': SimpleScene('YOU LOSE!', None, 'TITLE'),
}
scene = scenes['TITLE']

while True:

main()
Now we have a simple game that's replayable and easily extendable. Feel free to use this code for whatever you like.
