I tried making a version of the snake game in python using pygame. I am not receiving any errors, however when i press an arrow key, the snake does not change directions.
Here is my code:
Here is my code:
import pygame
import sys
import random
import time
pygame.init()
class Snake():
def __init__(self):
self.position = [100,50]
self.body = [[100,50],[90,50],[80,50]]
self.direction = "RIGHT"
def changeDirTo(self,dir):
if dir=="RIGHT" and not self.direction=="LEFT":
self.direction = "RIGHT"
elif dir=="LEFT" and not self.direction=="RIGHT":
self.direction = "LEFT"
elif dir=="UP" and not self.direction=="DOWN":
self.direction = "UP"
elif dir=="DOWN" and not self.direction=="UP":
self.direction = "DOWN"
def move(self,foodPos):
if self.direction == "RIGHT":
self.position[0] = self.position[0] + 10
elif self.direction == "LEFT":
self.position[0] = self.position[0] - 10
elif self.direction == "UP":
self.position[1] = self.position[1] - 10
elif self.direction == "DOWN":
self.position[1] = self.position[1] + 10
self.body.insert(0,list(self.position))
if self.position == foodPos:
return 1
else:
self.body.pop()
return 0
def move_Right(self):
self.position[0] = self.position[0] + 10
def move_Left(self):
self.position[0] = self.position[0] - 10

self.position[0] = self.position[1] - 10

self.position[0] = self.position[1] + 10
def checkCollision(self):
if self.position[0] > 490 or self.position[0] < 0:
return 1
elif self.position[1] > 490 or self.position[1] < 0:
return 1
for bodyPart in self.body[1:]:
if self.position == bodyPart:
return 1
return 0

gameOver()
pygame.display.set_caption("Snake | Score: " + str(score))
pygame.display.flip()
fps.tick(10)
pygame.quit()I've read over similar threads and I can't seem to find a solution. All help is appreciated.
