What this step does is:
1. Added super bombs and strengthened the replenishment function of bullets
2. After the user obtains the super bomb and strengthens the supply of bullets, the bullets will be strengthened first. At the same time, press the space bar to release the big move and empty the aircraft in the screen
First prepare resources, the network can also be downloaded, I directly use the tutorial resources here, why (really good, find their own miserable)
In the first few steps, the basic framework of the game is almost complete, which is to add a new function to the original framework. Here we add a new function called supply. Py: Supply control, including supply movement and reset
Import pygame from random import * # Bullet_Supply class (pygame.sprite.sprite): def __init__(self, bg_size): Self. Image = PyGame.image.load ('images/ bullet_supply-.png ').convert_alpha() Self.width = bg_size[0] self.height = bg_size[1] # get_rect() Self.rect = self.image.get_rect() # resupply position of random bullets. Randint (a,b) generates a<=n<=b, i.e., at the screen width, Left = randint(0, self.width - self.rect.width) self.rect.top = randint(-2 * self.height, Self. active = False # Self. speed = 5 # def move(self): If self. Rect. Top < self. Height: # if self. Self. Active = False # Def reset(self): Randint (a,b) generates a<=n<=b, i.e., at the screen width, Left = randint(0, self.width - self.rect.width) self.rect.top = randint(-2 * self.height, 0) # Bomb_Supply(pygame.sprite): def __init__(self, bg_size): Image = pygame.image.load('images/ bomb_supply-.png ').convert_alpha() # Self.width = bg_size[0] self.height = bg_size[1] # get_rect() Self.rect = self.image.get_rect() # resupply position of super bomb. Randint (a,b) generates a<=n<=b, i.e., at the screen width, Left = randint(0, self.width - self.rect.width) self.rect.top = randint(-2 * self.height, Self. active = False # Self. speed = 5 # def move(self): If self. Rect. Top < self. Height: # if self. Self. Active = False # Def reset(self): Randint (a,b) generates a<=n<=b, i.e., at the screen width, Self.rect. left = randint(0, self.width - self.rect.width) self.rect.top = randint(-2 * self.height, 0)Copy the codeMain.py: Added the rendering of super bullets, bullet timer events, resupply time events,
1. The ability to supply every 8 seconds, randomly selected (Super bombs/enhanced bullets)
2. Aircraft picking up supplies (handled by collision mechanism)
3. When you pick up a strengthened bullet, the bullet changes and the strengthened bullet lasts 4 seconds
4. Pick up the super bomb, the number of the super bomb changes (up to 3), at the same time the space put the super bomb big move, clear the screen notes as far as possible to write all write, write the feeling is a bit messy
