I'm importing pixelperfect and using one of its functions called check_collision(object1, object2) here's the website I got it from http://www.pygame.org/wiki/FastPixelPerfect when I use the function it always returns false, and I have no idea why. If anyone could help me or have a better way to do pixelperfect collision I would be grateful.
It's always returning false that's the problem.
Here's the code:
import pygame, pixelperfect
from pygame.locals import *
from pixelperfect import *
screen = pygame.display.set_mode([640, 480])
screen.fill([255,255,255])
pygame.display.flip()
class Ball(object):
def __init__(self, picture, speed, loc):
self.image = pygame.image.load(picture)
self.rect = self.image.get_rect()
self.rect.left, self.rect.top = loc
self.speed = speed
def move(self):
self.rect = self.rect.move(self.speed)
if self.rect.left < 0 or self.rect.right > screen.get_width():
self.speed[0] = - self.speed[0]
elif self.rect.top < 0 or self.rect.bottom > screen.get_height():
self.speed[1] = - self.speed[1]
ball = Ball("beach_ball.png", [5,5], [0,0])
ball.rect.center = [80, 50]
ball2 = Ball("beach_ball.png", [-5,-5], [200, 200])
ball2.rect.center = [100, 200]
clock = pygame.time.Clock()
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
screen.fill([255,255,255])
ball.move()
ball2.move()
if check_collision(ball, ball2):
print 'hit'
screen.blit(ball.image, ball.rect)
screen.blit(ball2.image, ball2.rect)
pygame.display.flip()
clock.tick(30)
pygame.quit()
From the page you provided:
All objects must have a 'rect' attribute and a 'hitmask' attribute.
You only implemented rect. It uses the hitmap to check if there is a collision and since you don't provide one it returns false.
Edit: Try using get_full_hitmask(image, rect) to get a hitmask, and add it to the object.
