Python Game Programming Tutorial: Snake Game Part 4

[@aafiyamemon9535]

you deserve more subscribers, the way you explain is really awesome!

[@robertlouis5721]

Your videos are simply phenomenal as they offer the viewer the opportunity to learn complex systems that could improve an understanding of coding. Thank you for taking the time to make these tutorials.

[@idkhow9603]

this is the best tutorial i have seen so far. Thanks so much

[@cyndinorwood7841]

Just an FYI for the #Move the end segments first in reverse order. I changed the 0 to a -1 to get rid of the grey segment that was appearing after I ran the program each time. So if you see this, the way to fix it is to change this line here for index in range(len(segments)-1, 0, -1) .....change the 0 to a -1 This is an excellent tutorial Christian Thompson.

I think it is better to use: if head.distance(food) < 20: x = random.randrange(-280, 280, 20) y = random.randrange(-280, 280, 20) food.goto(x, y) this way the food spawn in the path of the snake

When the snake eats the 1st food the segment is left at the centre , but after eating the 2nd food the segments joins! Why??? I checked the codes, but they were fine!

[@reeddhimansaha2782]

I followed the tutorial exactly. Whenever the snake hits the food, the segment does not get appended to the snake head. It remains there itself and food changes its color to grey. Can you please help out with that?

you mentioned there was an alternative method to create the segments by using a temp variable, is that method easier than this? And if so, could u explain how to do that method?

When the game starts my snake already has an extra segment and when I run into the food the new segments go to the middle. I don't know what I'm doing wrong so it would be great if you could help me.

[@ghosttm3823]

I wanted to ask you how I can configure the same element that is food but it takes away your body, it does nothing for the score and you can continue playing until you play it again with your head without having a body, any idea on how to configure it, I am very new to this

[@TokyoEdTech]

It's not super complicated - you need to add the item; basically do the same thing you did with the food. When you collide you need to move the last segment off the screen and remove it from the body. It would be something like: segments[-1].goto(1000, 1000) del segments[-1] Hopefully that will point you in the right direction.

[@minonakura8858]

Do you mind explaining to me why the body parts don't just stack on top of the head? doesn't setting X and Y to the head.x/ycor() mean that the body parts are at the same coordinates as the head?

I made the game smoother by making the delay 0.0075 and doing this: if head.direction == "up": y = head.ycor() head.sety(y + 1(instead of 20)) if head.direction == "down": y = head.ycor() head.sety(y - 1(instead of 20)) if head.direction == "right": x = head.xcor() head.setx(x + 1(instead of 20)) if head.direction == "left": x = head.xcor() head.setx(x - 1(instead of 20)) If I set everything back to normal delay and change the 1 to 20, it works fine, but with this code the new sections of the snake appear at the position of the head, not behind it. Any help is appreciated! Or is there a way to make it smoother without changing those values?

Another implementation would perhaps be creating individual segments every time the snake moves and having a counter go down for each segment until it's on the tip of the tail and dies next

[@mcreallyfunky]

Hello! Great tutorial. I was wondering if there is a way to make another food item (maybe something like a grape along with the red apple) that would add more segments than the apple would (ex: apple adds 1 segment onto the snake but grape adds 2 segments)? Any help at all would be appreciated! (also having them both be on screen simultaneously)

[@TokyoEdTech]

Adding the grape is pretty trivial - just copy the apple code and rename it (but a loop would work better). Adding two segments is a bit tricky as you have to add a segment, move, then add the next segment.

hi can you help me, when i start the game my snake body is not finishing and just goes after head import turtle import time import random delay = 0.1 pitto = turtle.Screen() pitto.title("Snake Game") pitto.bgcolor("lime") pitto.setup(width=800, height=800) pitto.tracer(0) head = turtle.Turtle() head.speed(0) head.shape("circle") head.color("green") head.penup() head.goto(0,0) head.direction = "stop" food = turtle.Turtle() food.speed(0) food.shape("triangle") food.color("red") food.penup() food.goto(0,120) segments = [] def move(): if head.direction == "up": y = head.ycor() head.sety(y + 20) if head.direction == "down": y = head.ycor() head.sety(y - 20) if head.direction == "left": x = head.xcor() head.setx(x - 20) if head.direction == "right": x = head.xcor() head.setx(x + 20) def go_up(): head.direction = "up" def go_down(): head.direction = "down" def go_left(): head.direction = "left" def go_right(): head.direction = "right" pitto.listen() pitto.onkeypress(go_up, "w") pitto.onkeypress(go_down, "s") pitto.onkeypress(go_left, "a") pitto.onkeypress(go_right, "d") while True: pitto.update() new_segment = turtle.Turtle() new_segment.speed(0) new_segment.shape("square") new_segment.color("forestgreen") new_segment.penup() segments.append(new_segment) for index in range(len(segments) -1, 0, -1): x = segments[index-1].xcor() y = segments[index-1].ycor() segments[index].goto(x, y) if len(segments) > 0: x = head.xcor() y = head.ycor() segments[0].goto(x, y) if head.distance(food) < 20: x = random.randint(-290,290) y = random.randint(-290,290) food.goto(x, y) move() time.sleep(delay) pitto.mainloop()

Your code is out of order and indented incorrectly: import turtle import time import random delay = 0.1 pitto = turtle.Screen() pitto.title("Snake Game") pitto.bgcolor("lime") pitto.setup(width=800, height=800) pitto.tracer(0) head = turtle.Turtle() head.speed(0) head.shape("circle") head.color("green") head.penup() head.goto(0,0) head.direction = "stop" food = turtle.Turtle() food.speed(0) food.shape("triangle") food.color("red") food.penup() food.goto(0,120) segments = [] def move(): if head.direction == "up": y = head.ycor() head.sety(y + 20) if head.direction == "down": y = head.ycor() head.sety(y - 20) if head.direction == "left": x = head.xcor() head.setx(x - 20) if head.direction == "right": x = head.xcor() head.setx(x + 20) def go_up(): head.direction = "up" def go_down(): head.direction = "down" def go_left(): head.direction = "left" def go_right(): head.direction = "right" pitto.listen() pitto.onkeypress(go_up, "w") pitto.onkeypress(go_down, "s") pitto.onkeypress(go_left, "a") pitto.onkeypress(go_right, "d") while True: pitto.update() for index in range(len(segments) -1, 0, -1): x = segments[index-1].xcor() y = segments[index-1].ycor() segments[index].goto(x, y) if len(segments) > 0: x = head.xcor() y = head.ycor() segments[0].goto(x, y) if head.distance(food) < 20: x = random.randint(-290,290) y = random.randint(-290,290) food.goto(x, y) new_segment = turtle.Turtle() new_segment.speed(0) new_segment.shape("square") new_segment.color("forestgreen") new_segment.penup() segments.append(new_segment) move() time.sleep(delay) pitto.mainloop()

after eating the first food the first body part spawns in the middle then when I eat another it syncs up with the head?

@@TokyoEdTech Tried to see what the problem was but didnt find it, so i copied the link in the description, deleted the code that I didnt have in my first code and continued following your tutorial

hi i have a problem where whenever the snake touches food the game crashes. Do you think you could help me? heres the code: #snake game import turtle import time import random delay = 0.1 # set up the screen wn = turtle.Screen() wn.title("Snake Game") wn.bgcolor("green") wn.setup(width=600, height=600) wn.tracer(0) # turns off the screen updates #snake head head = turtle.Turtle() head.speed(0) head.shape("square") head.color("black") head.penup() head.goto(0,0) head.direction = "stop" # Snake Food food = turtle.Turtle() food.speed(0) food.shape("square") food.color("red") food.penup() food.goto(0,100) food.direction = "stop" segnents = [] # functions def go_up(): head.direction = "up" def go_down(): head.direction = "down" def go_left(): head.direction = "left" def go_right(): head.direction = "right" def move(): if head.direction == "up": y = head.ycor() head.sety(y + 20) if head.direction == "down": y = head.ycor() head.sety(y - 20) if head.direction == "left": x = head.xcor() head.setx(x - 20) if head.direction == "right": x = head.xcor() head.setx(x + 20) # keyboard bindings wn.listen() wn.onkeypress(go_up, "w") wn.onkeypress(go_down, "s") wn.onkeypress(go_left, "a") wn.onkeypress(go_right, "d") # main game loop while True: wn.update() #check for a collision with the food if head.distance(food) < 20: # move food to random position x = random.randint(-300, 300) y = random.randint(-300, 300) food.goto(x, y) #add a segment new_segment = turtle.Turtle() new_segment.speed(0) new_segment.shape("square") new_segment.color("grey") new_segment.penup() segments.append(new_segment) move() time.sleep(delay) wn.mainloop()

it also says that "segments" is not defined here is the code: #add a segment new_segment = turtle.Turtle() new_segment.speed(0) new_segment.shape("square") new_segment.color("grey") new_segment.penup() segments.append(new_segment)

Earlier in the program you should have a line like: segments = [] Check your spelling.
