I'm working on my school project for which im designing a 2D game.
I have 3 images, one is the player and the other 2 are instances (coffee and computer). What i want to do is, when the player image collides with one of the 2 instances i want the program to print something.
I'm unsure if image collision is possible. But i know rect collision is possible. However, after several failed attempts, i can't manage to make my images rects. Somebody please help me. Here is my source code:
import pygame
import os
black=(0,0,0)
white=(255,255,255)
blue=(0,0,255)
class Player(object):
def __init__(self):
self.image = pygame.image.load("player1.png")
self.image2 = pygame.transform.flip(self.image, True, False)
self.coffee=pygame.image.load("coffee.png")
self.computer=pygame.image.load("computer.png")
self.flipped = False
self.x = 0
self.y = 0
def handle_keys(self):
""" Movement keys """
key = pygame.key.get_pressed()
dist = 5
if key[pygame.K_DOWN]:
self.y += dist
elif key[pygame.K_UP]:
self.y -= dist
if key[pygame.K_RIGHT]:
self.x += dist
self.flipped = False
elif key[pygame.K_LEFT]:
self.x -= dist
self.flipped = True
def draw(self, surface):
if self.flipped:
image = self.image2
else:
im = self.image
for x in range(0, 810, 10):
pygame.draw.rect(screen, black, [x, 0, 10, 10])
pygame.draw.rect(screen, black, [x, 610, 10, 10])
for x in range(0, 610, 10):
pygame.draw.rect(screen, black, [0, x, 10, 10])
pygame.draw.rect(screen, black, [810, x, 10, 10])
surface.blit(self.coffee, (725,500))
surface.blit(self.computer,(15,500))
surface.blit(im, (self.x, self.y))
pygame.init()
screen = pygame.display.set_mode((800, 600))#creates the screen
player = Player()
clock = pygame.time.Clock()
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit() # quit the screen
running = False
player.handle_keys() # movement keys
screen.fill((255,255,255)) # fill the screen with white
player.draw(screen) # draw the player to the screen
pygame.display.update() # update the screen
clock.tick(60) # Limits Frames Per Second to 60 or less
Use pygame.Rect() to keep image size and position.
Image (or rather pygame.Surface()
) has function get_rect()
which returns pygame.Rect()
with image size (and position).
self.rect = self.image.get_rect()
Now you can set start position ie. (0, 0)
self.rect.x = 0
self.rect.y = 0
# or
self.rect.topleft = (0, 0)
# or
self.rect = self.image.get_rect(x=0, y=0)
(Rect
use left top corner as (x,y)).
Use it to change position
self.rect.x += dist
and to draw image
surface.blit(self.image, self.rect)
and then you can test collision
if self.rect.colliderect(self.rect_coffe):
BTW: and now class Player
looks almost like pygame.sprite.Sprite :)
