The goal is

• Understand collision detection methods
• Collision implementation

One 、 Understand collision detection methods

pygame Provides Two are very convenient The method can realize collision detection ：

pygame.sprite.groupcollide()

• Two elf groups in All the elves Collision detection based on

groupcollide(group1, group2, dokill1, dokill2, collided = None) -> Sprite_dict

• If you will dokill Set to True, be Colliding sprites will be automatically removed
• collided Parameters are used for Callback function to calculate collision
  • If not specified , Then each elf must have one rect attribute

pygame.sprite.spritecollide()

• Judge Some elf and Specify the sprite group The collision of elves in

spritecollide(sprite, group, dokill, collided = None) -> Sprite_list

• If you will dokill Set to True, be Specify the sprite group in Colliding sprites will be automatically removed
• collided Parameters are used for Callback function to calculate collision
  • If not specified , Then each elf must have one rect attribute
• return Spirit group Middle heel spirit There was a collision List of elves

Two 、 Collision implementation

def __check_collide(self):

    # 1.  The bullet destroyed the enemy plane 
    pygame.sprite.groupcollide(self.hero.bullets, self.enemy_group, True, True)
    
    # 2.  The enemy plane crashed the hero 
    enemies = pygame.sprite.spritecollide(self.hero, self.enemy_group, True)
    
    #  Judge whether there is content in the list 
    if len(enemies) > 0:
    
        #  Let the hero die 
        self.hero.kill()
        
        #  End the game 
        PlaneGame.__game_over()

summary

This chapter is the final chapter of the aircraft war , Combine the contents of previous chapters , Write here , The whole game is finished , Interested friends do it by themselves ! Tomorrow, all the implementation source codes of the aircraft war will be released , Don't miss your favorite friends !
Where are the deficiencies or better suggestions , Welcome to make complaints about Tucao , There is a little friend who doesn't understand can confide in me , I will answer them one by one , Thank you for your approval , Thank you for your support !
