title: Pygame: Code runs but there is no hit detection with targets and crosshair
body: <p>I am trying to create hit detection with the targets in my game. Currently I have drawn a crosshair and enemy targets on screen, but clicking on the targets does not move them (they are not to be deleted, they should just respawn at the top of the screen). Apologies, I am new to coding and stackoverflow. I've only included code related to the issue. Here is my code:</p>
  <pre class="lang-py prettyprint-override"><code>import pygame  
  import random  
  
  pygame.init()  
  width, height = 800, 600  
  screen = pygame.display.set_mode((width, height))  
  pygame.display.set_caption('Shooter Game')  # caption not necessary  
  pygame.mouse.set_visible(False)  
  
  cross_hair = pygame.image.load('crosshair.png')
  
  enemyImg = []  
  enemyX = []  
  enemyY = []  
  enemyX_change = []  
  enemyY_change = []  
  numberOfEnemies = 6  
  
  for i in range(numberOfEnemies):    
      enemyImg.append(pygame.image.load('enemy.png'))  
      enemyX.append(random.randint(0, 800))  
      enemyY.append(random.randint(50, 80))  
      enemyX_change.append(1)  
      enemyY_change.append(40)  
  
  def enemy(x, y, i):  
      screen.blit(enemyImg[i], (x, y))
  
  running = True  
  while running:
  
      screen.fill((128, 128, 128))  
      screen.blit(background, (0, 0))  
  
      for event in pygame.event.get():  
          if event.type == pygame.QUIT:  
              running = False  
          if event.type == pygame.MOUSEMOTION:  
              mouseX = event.pos[0]  
              mouseY = event.pos[1]  
          if event.type == pygame.MOUSEBUTTONDOWN:  
              pygame.mixer.Channel(0).play(shootSound)  
              for something in range(numberOfEnemies):  
                  theImg = enemyImg[something]  
                  rectangle = theImg.get_rect()  
                  pos = pygame.mouse.get_pos()  
                  if pos[0] &gt; rectangle.topleft[0] and pos[0] &lt; rectangle.bottomright[0] \  
                          and pos[1] &gt; rectangle.topleft[1] and pos[1] &lt; rectangle.bottomright[1]:  
                      ####THE ISSUE IS THE LINES ABOVE THIS ##### 
                      enemyX = random.randint(0, 800)  
                      enemyY = random.randint(50, 150)  
                      score_value += 1
