[PyGame] adding mouse control to game

[flash77]

Hi,

thank you for answering...

I think, I got it now...

Because there were problems, if

self.rect.centerx = max(self.xmin, min(self.xmax, xpos))

is inside the function "spaceship.update()"
I put it in a own function "move()".

Now it works...

#create spaceship class
class Spaceship(pygame.sprite.Sprite):
	def __init__(self, x, y, health):
		pygame.sprite.Sprite.__init__(self)
		self.x = x
		self.y = y
		self.health_start = health
		self.health_remaining = health
		self.image = pygame.image.load("images/ship.png")
		self.rect = self.image.get_rect()
		self.rect.center = [x, y]
		self.xmin = self.rect.width // 2  # Compute Spaceship x range.
		self.xmax = screen_width - self.xmin
		self.last_shot = pygame.time.get_ticks()

	def move(self, xpos):
		self.rect.centerx = max(self.xmin, min(self.xmax, xpos))

	def update(self):
		#set a cooldown variable
		cooldown = 500 #milliseconds
		game_over = 0
		#record current time
		time_now = pygame.time.get_ticks()
		#shoot, get key press
		key = pygame.key.get_pressed()
		if key[pygame.K_SPACE] and time_now - self.last_shot > cooldown:
			#laser_fx.play()
			bullet_1 = Bullets(self.rect.centerx - 43, self.rect.top)
			bullet_2 = Bullets(self.rect.centerx + 43, self.rect.top)
			#bullet = Bullets(self.rect.centerx, self.rect.top)
			bullet_group.add(bullet_1)
			bullet_group.add(bullet_2)
			self.last_shot = time_now

		#update mask
		self.mask = pygame.mask.from_surface(self.image)

		#draw health bar
		pygame.draw.rect(screen, red, (self.rect.x, (self.rect.bottom + 10), self.rect.width, 15))
		if self.health_remaining > 0:
			pygame.draw.rect(screen, green, (self.rect.x, (self.rect.bottom + 10), int(self.rect.width * (self.health_remaining / self.health_start)), 15))
		elif self.health_remaining <= 0:
			explosion = Explosion(self.rect.centerx, self.rect.centery, 3)
			explosion_group.add(explosion)
			self.kill()
			game_over = -1
		return game_over
