Question

我试图制作一个简单的游戏，其中有士兵向你走来，当你点击它们“杀死”他们时，他们走到屏幕后面，开始向你走来，等等...... 但我有pygame鼠标点击事件的麻烦，它只是不起作用。到目前为止，我的代码是：

import pygame, math
from random import randrange

import sys, math, pygame
from operator import itemgetter

def getKey(customobj):
    return customobj.getKey()

class Point3D:
    def __init__(self, imfiles, nfrm, x = 0, y = 0, z = 0):
        self.x, self.y, self.z = float(x), float(y), float(z)
        self.frms = []
        self.nfrm=nfrm
        self.index=0
        for k in range(0,nfrm):
            im=pygame.image.load(imfiles+'_'+str(k+1)+'.png')
            im.set_colorkey((0,0,0))
            self.frms.append(im)       

    def

    project(self, win_width, win_height, fov, viewer_distance):
    """ Transforms this 3D point to 2D using a perspective projection. """
    factor = fov / (viewer_distance + self.z)
    x = self.x * factor + win_width / 2
    y = -self.y * factor + win_height / 2
    return Point3D(x, y, self.z)

def draw3D(self, wsurface, fov, viewer_distance, max_depth):
    win_width=wsurface.get_width()
    win_height=wsurface.get_height()
    factor = fov / (viewer_distance + self.z)
    x = self.x * factor + win_width / 2
    y = -self.y * factor + win_height / 2
    size = int((1 - float(self.z) / max_depth) * 64)
    im=pygame.transform.smoothscale(self.frms[self.index],(size,size))
    try:
        wsurface.blit(im, (x, y))
    except:
        print((x,y))
    self.index=self.index+1
    if self.index >= self.nfrm:
      self.index=0

def getKey(self):
    return -self.z


class StartField:
def __init__(self, num_stars, max_depth):
    pygame.init()

    myWin = pygame.display.set_mode((640, 450), 0, 32)
    pygame.display.set_caption('Drawing')

    self.screen = myWin.subsurface([0,0,640,400]);
    self.txtwin = myWin.subsurface([0,400,640,50]);
    pygame.display.set_caption("Task C")

    self.clock = pygame.time.Clock()
    self.num_stars = num_stars
    self.max_depth = max_depth

    self.init_stars()

def init_stars(self):
    """ Create the starfield """
    self.stars = []
    for i in range(self.num_stars):
        # A star is represented as a list with this format: [X,Y,Z]
        star = Point3D('im',8,randrange(-25,25), randrange(-25,25), randrange(1, self.max_depth))
        self.stars.append(star)

def move_and_draw_stars(self):
    """ Move and draw the stars """
    origin_x = self.screen.get_width() / 2
    origin_y = self.screen.get_height() / 2

    stars=sorted(self.stars,key = getKey)

    for star in stars:
        # The Z component is decreased on each frame.
        star.z -= 0.05

        # If the star has past the screen (I mean Z<=0) then we
        # reposition it far away from the screen (Z=max_depth)
        # with random X and Y coordinates.
        if star.z <= 0:
            star.x = randrange(-25,25)
            star.y = randrange(-25,25)
            star.z = self.max_depth

        # Convert the 3D coordinates to 2D using perspective projection.
        star.draw3D(self.screen, 128, 0, self.max_depth)

def run(self):
    """ Main Loop """        
    bgPicture =    pygame.transform.smoothscale(pygame.image.load('Starfield.jpg'),(self.screen.get_width(),self.screen.get_height()))
    font = pygame.font.Font(None, 36)       

    while 1:
        # Lock the framerate at 50 FPS.
        self.clock.tick(50)

        # Handle events.
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                return

        self.screen.blit(bgPicture, [0,0])
        self.move_and_draw_stars()

        # Text window outputs
        self.txtwin.fill([200,200,200])
        text = font.render("Total Score: ", 1, (10, 10, 10))
        self.txtwin.blit(text, [5, 5])

        pygame.display.update()

  if __name__ == "__main__":
  StartField(256, 24).run()


        pygame.init()
        pygame.mixer.init()
        sounda= pygame.mixer.Sound("MuseUprising.mp3")

        sounda.play()

测试鼠标左键：

if event.type == pygame.MOUSEBUTTONDOWN and pygame.mouse.get_pressed()[0]:

如果给士兵一个pygame.Rect你可以使用它来检查与鼠标指针的碰撞，如下所示：

mouse_pos = pygame.mouse.get_pos()
if event.type == pygame.MOUSEBUTTONDOWN and pygame.mouse.get_pressed()[0] and self.rect.collidepoint(mouse_pos):

Python：pygame在鼠标单击时删除图像并再次创建它
