I'm working in pygame & python and trying to make a zombie shooting game. It all worked smoothly until I tried to add the collision system. If you also know how to add a collision system for this game please leave a comment with a full code.
The error:
type object 'bullet' has no attribute 'rect'
File "C:\Users\*\Desktop\Zombie!\main.py", line 172, in game
collide = pygame.sprite.spritecollide(bullet, enemiesList, False)
File "C:\Users\*\Desktop\Zombie!\main.py", line 44, in menu
game()
File "C:\Users\*\Desktop\Zombie!\main.py", line 211, in <module>

I am pretty sure I assigned self.rect at the bullet class, I checked the indents and the spelling but I can't to seem to find the error.
CodePudding user response：
pygame.sprite.spritecollide - assumes that first parameter is an instance of a class which has 'rect' attribute. But you put the class itself there.
I believe the code must looks like this:
for bullets_ in bullets:
collide = pygame.sprite.spritecollide(bullets_, enemiesList, False)
CodePudding user response：
Look at the error: type error bullet ... . Somewhere, you're using the bullet class name instead of using an instance of that class.
CodePudding user response：
You have a Group bullets and a Group enemiesList. Use pygame.sprite.groupcollide() to detect collisions between Sprites in Groups:
collide = pygame.sprite.groupcollide(bullets, enemiesList, False, False)
