This Free Friday I am working on a project on YouTube a Snake Game part 2.
class MAIN:
def __init__(self):
self.snake = SNAKE()
self.fruit = FRUIT()
def update(self):
self.snake.move_snake()
def draw_elements(self):
self.fruit.draw_fruit()
self.snake.draw_fruit()
def check_collisiion(self):
if self.fruit.pos == self.snake.body[0]:
self.fruit.randomize()
self.snake.add_block()- This is a third class called main it will contain the entire game logic and the snake and fruit object.
class FRUIT:
def __init__(self):
self.randomize()
def draw_fruit(self):
fruit_rect = pygame.Rect(int(self.pos.x * cell_size),int(self.pos.y * cell_size),cell_size,cell_size)
pygame.draw.rect(screen,(126,166,114),fruit_rect)
def randomize(self):
self.x = random.randint(0,cell_number - 1)
self.y = random.randint(10,cell_number - 1)
self.pos = Vector2(self.x,self.y)
- This is a more updated code of the class fruit.
class SNAKE:
def __init__(self):
self.body = [Vector2(5,10), Vector2(6,10), Vector2(7,10)]
self.direction = Vector2(1,0)
self.new_block = False
def draw_snake(self):
for block in self.body:
x_pos -=int(block.x * cell_size)
y_pos -= int(block.y * cell_size)
block_rect = pygame.rect(x_pos,y_pos,cell_size,cell_size)
pygame.draw.rect(screen,(183,191,122),block_rect)
def move_snake(self):
if self.new_block == True:
body_copy = self.body[:]
body_copy.insert(0,body_copy[0] + self.direction)
self.body = body_copy[:]
self.new_block = False
else:
body_copy = self.body[:-1]
body_copy.insert(0,body_copy[0] + self.direction)
self.body = body_copy[:]
def add_block(self):
self.new_block = True- This is a more updated code of the class snake.
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == SCREEN_UPDATE:
main_game.update()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP:
main_game.snake.direction = Vector2(0,-1)
if event.key == pygame.K_RIGHT:
main_game.snake.direction = Vector2(1,0)
if event.key == pygame.K_DOWN:
main_game.snake.direction = Vector2(0,1)
if event.key == pygame.K_LEFT:
main_game.snake.direction = Vector2(-1,0)- This part of the code is for the snake to move up, down and right, to left.
