How to Use Sprite Collide in Pygame
34,824
Solution 1
def checkCollision(sprite1, sprite2):
col = pygame.sprite.collide_rect(sprite1, sprite2)
if col == True:
sys.exit()
should be
def checkCollision(self, sprite1, sprite2):
col = pygame.sprite.collide_rect(sprite1, sprite2)
if col == True:
sys.exit()
since it's a method bound to an object.
Solution 2
You have this:
col = pygame.sprite.collide_rect(sprite1, sprite2)
But an easier way to do this would be to simply use colliderect which is a function of rect. It might be easier to try this:
col=sprite1.rect.colliderect(sprite2.rect)
Solution 3
Change
def checkCollision(sprite1, sprite2):
To
def checkCollision(self, sprite1, sprite2):
And you don't have to check the collision on every event, reduce the indent of rock.checkCollision(bird.image_b, rock.image_b)
by 1.

I am making a very simple game where the bird (player) has to dodge the rock and if it gets hit by the rock you lose. I am trying to use pygame.sprite.collide_rect() to tell if they touched but I cant seem to figure how to correctly use it.
Here is my code:
import pygame import os, sys import random import time img_path = os.path.join('C:\Python27', 'player.png') img_path2 = os.path.join('C:\Python27', 'rock.png') class Bird(object): def __init__(self): self.image_s = pygame.image.load(img_path) self.image_b = self.image_s.get_rect() self.x = 0 self.y = 0 def handle_keys(self): key = pygame.key.get_pressed() dist = 2 if key[pygame.K_DOWN]: self.y += dist elif key[pygame.K_UP]: self.y -= dist if key[pygame.K_RIGHT]: self.x += dist elif key[pygame.K_LEFT]: self.x -= dist def draw(self, surface): surface.blit(self.image, (self.x, self.y)) def background(self, surface): bg = os.path.join('C:\Python27', 'bg.png') self.image2 = pygame.image.load(bg) surface.blit(self.image2, (0,0)) class Rock(object): def __init__(self, x=640, y=0,): self.image_s = pygame.image.load(img_path2) self.image_b = self.image_s.get_rect() self.x = x self.y = y dist = 10 self.dist = dist def rock(self): dist = 10 self.x -=dist def rock_draw(self, surface): surface.blit(self.image, (self.x, self.y)) def checkCollision(sprite1, sprite2): col = pygame.sprite.collide_rect(sprite1, sprite2) if col == True: sys.exit() pygame.init() screen = pygame.display.set_mode((640, 200)) bird = Bird() rock = Rock() clock = pygame.time.Clock() running = True while running: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() running = False if rock.x < 0: y = random.randint(10, 190) rock = Rock(640, y) rock.checkCollision(bird.image_b, rock.image_b) bird.handle_keys() rock.rock() screen.fill((255,255,255)) bird.background(screen) bird.draw(screen) rock.rock_draw(screen) pygame.display.update() clock.tick(40)
When I try to run it it tells me it only takes 2 arguments and I gave three when I try to fix that I get all kinds of different error messages.
