python - Pygame: Spaceinvaders: can't shoot bullets -
i building mockup of space invaders. want make user shoot stuff , invaders die (1hit kill), can't seem figure out how that. have tried drawing small rectangle, background paints on it. help!

take @ minimal space invaders-like game i've written question:
import pygame # you'll able shoot every 450ms reload_speed = 450 # foes move every 1000ms sideways , every 3500ms down move_side = 1000 move_down = 3500 screen = pygame.display.set_mode((300, 200)) clock = pygame.time.clock() pygame.display.set_caption("micro invader") # create bunch of events move_side_event = pygame.userevent + 1 move_down_event = pygame.userevent + 2 reloaded_event = pygame.userevent + 3 move_left, reloaded = true, true invaders, colors, shots = [], [] ,[] x in range(15, 300, 15): y in range(10, 100, 15): invaders.append(pygame.rect(x, y, 7, 7)) colors.append(((x * 0.7) % 256, (y * 2.4) % 256)) # set timer movement events pygame.time.set_timer(move_side_event, move_side) pygame.time.set_timer(move_down_event, move_down) player = pygame.rect(150, 180, 10, 7) while true: clock.tick(40) if pygame.event.get(pygame.quit): break e in pygame.event.get(): if e.type == move_side_event: invader in invaders: invader.move_ip((-10 if move_left else 10, 0)) move_left = not move_left elif e.type == move_down_event: invader in invaders: invader.move_ip(0, 10) elif e.type == reloaded_event: # when reload timer runs out, reset reloaded = true pygame.time.set_timer(reloaded_event, 0) shot in shots[:]: shot.move_ip((0, -4)) if not screen.get_rect().contains(shot): shots.remove(shot) else: hit = false invader in invaders[:]: if invader.colliderect(shot): hit = true = invaders.index(invader) del colors[i] del invaders[i] if hit: shots.remove(shot) pressed = pygame.key.get_pressed() if pressed[pygame.k_left]: player.move_ip((-4, 0)) if pressed[pygame.k_right]: player.move_ip((4, 0)) if pressed[pygame.k_space]: if reloaded: shots.append(player.copy()) reloaded = false # when shooting, create timeout of reload_speed pygame.time.set_timer(reloaded_event, reload_speed) player.clamp_ip(screen.get_rect()) screen.fill((0, 0, 0)) invader, (a, b) in zip(invaders, colors): pygame.draw.rect(screen, (150, a, b), invader) shot in shots: pygame.draw.rect(screen, (255, 180, 0), shot) pygame.draw.rect(screen, (180, 180, 180), player) pygame.display.flip() it uses colliderect detect collisions, code missing.
also, code in general , movement code lot simpler yours; maybe can serve inspiration you.
