3 Build a AirForce Game step by step (Part 3)
3.8 Step8: Load sound and play music
-
prepare sound and music download sounds
-
initial sound and music
#8 initial load sound shooting_sound = pygame.mixer.Sound('sounds/pew.wav') pygame.mixer.music.load('sounds/BG.ogg') pygame.mixer.music.play(-1) ## makes the gameplay sound in an endless loop -
add the sound in the collision check
if bulletRect.colliderect(enemyRect):
enemys.pop(enemy_index)
bullets.pop(bullet_index)
# step7 play explosion in the location of enemy
explosions.append([enemyPos,0,explosion_time])

3.9 Step9: Draw text for score, life and game over
- initial the score, life
#initial for step 9
score=0
life=3
game_over=False
- define function for draw text
def draw_text(surf, text, size, x, y):
## selecting a cross platform font to display the score
font = pygame.font.Font(pygame.font.match_font('arial'), size)
text_surface = font.render(text, True, BLACK) ## True denotes the font to be anti-aliased
text_rect = text_surface.get_rect()
text_rect.midtop = (x, y)
surf.blit(text_surface, text_rect)
- draw life and score after load background
screen.blit(background,(0,0))
#step 9 draw life and score on
game_over=life<1 #step9 make game over if life small then 1
draw_text(screen, "Score: "+str(score), 18, width -100, 10)
draw_text(screen, "Life: "+str(life), 18, width/2, 10)
if(game_over):
draw_text(screen, "Game Over", 50, width/2, height/2 -40)
- add condition on game over
if(not game_over):
screen.blit(player, player_pos)
