title: Pygame point image towards mouse
body: <p>I am trying to get this image 'spaceship' to point towards my mouse on screen, proving to be quite difficult so I would appreciate any help :O Also, would appreciate it if you could help with moving an image towards the cursor, i'm guessing that would be quite similar to rotating towards it..
  Heres my code:</p>
  
  <pre><code>import sys, pygame, math;
  from pygame.locals import *;
  spaceship = ('spaceship.png')
  mouse_c = ('crosshair.png')
  backg = ('background.jpg')
  pygame.init()
  screen = pygame.display.set_mode((800, 600))
  bk = pygame.image.load(backg).convert_alpha()
  mousec = pygame.image.load(mouse_c).convert_alpha()
  space_ship = pygame.image.load(spaceship).convert_alpha()
  clock = pygame.time.Clock()
  pygame.mouse.set_visible(False)
  while True:
      for event in pygame.event.get():
          if event.type == QUIT:
              pygame.quit()
              sys.exit()
          elif event.type == MOUSEBUTTONDOWN and event.button == 1:
              print("test1")
          elif event.type == MOUSEBUTTONDOWN and event.button == 3:
              print("test3")
      screen.blit(bk, (0, 0))
      pos = pygame.mouse.get_pos()
      screen.blit(mousec, (pos))
      screen.blit(space_ship, (400, 300)) #I need space_ship to rotate towards my cursor
      pygame.display.update()
  </code></pre>
