Python：pygame删除鼠标点击图像并再次创建它

Question

即时尝试做一个简单的游戏，其中有士兵向你走来，当你点击它们“杀死”他们，他们在屏幕后面，并开始来到你身边，等..... 但是我有pygame鼠标点击事件的麻烦，它只是不工作。 继承人到目前为止我的代码：

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

    self.init_stars()

    for i in range(self.num_stars): 
     # A star is represented as a list with this format: [X,Y,Z]

    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.

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

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

     # Handle events. 
     for event in pygame.event.get():

       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()

要测试鼠标左键：

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

如果给战士一个pygame.Rect你可以使用鼠标指针等以检查碰撞这个：

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