Rotation based on end points

Question

I\'m using pygame to draw a line between two arbitrary points. I also want to append arrows at the end of the lines that face outward in the directions the line is traveling.

Answer 1

just to append to the above code, you'd probably want an event loop so it wouldn't quit right away:

...
clock = pygame.time.Clock()
running = True

while (running):
    clock.tick()
