Python Game Programming Tutorial: Snake Game Part 6

YOU'RE A DAMN GOOD TEACHER SIR 😁. Thank u for your service!

No one can teach programming better than you...you are an awesome teacher...plz contine to make more videos on python... I am a newbie...hope to learn more from you in the upcoming videos...

[@richardtanner5343]

I was having the same issue where the game would stop whenever I ate a piece of food. I figured it was due to the segment being within that 20 range. I changed my distance to less than 10 and it resolved for me

[@jeanjoubert10]

Thanks

[@shashankyh3366]

Thanks bro...........

[@lucagentile7841]

an other way to solve can be writing the first "for" in the body collision as "for segment in segments[1:]:", the first segment won't be considered anymore

[@laurensvanduin656]

@@lucagentile7841 I have tried both and it didn't work, do you guys happen to have any other suggestions? when i do "for segment in segments[1:]:" i get one body segment but now it shuts down when i try to get the second piece of food.

I get an idea from your part7 Video to hide the turtle wenn it collision happens. for s in segments: s.hideturtle() yeah, it doesn't delete the Object, but i found it a little bit eleganter to hide the Turtle than set it off the screen. I always think, it's much more important to know how to teach than the Knowledge the Teacher has. You are a very good example of that, i really appreciate it ! I have learnd you Pong Game Turorial, after this Snake Game, i am going to learn your next Space Invaders Game :)

very helpful please keep uploading !

[@alvitocabral]

If anyone is facing an issue when when you eat the food, the game resets and head gets sent back to (0,0), then this might help you out. Add in a print function as "print(segment.distance(head))" after "for segment in segments:" - When I did this it told me that the distance was 10 (instead of 20 like it's supposed to be... not sure why). So then I simply update the code to be a value

Hi! I found an issue where the snake would reset when when it picked up the food it reset no matter the distance I set it to, would this be a problem with the programing its self or the computer?

[@nadaghanem4627]

Thanks. I don't know how you managed to make body collision works. I tried it but it always clears the segments without a collision. The reason is that the first segment is already attached to the body so we need to check the collision from the second segment till the end.

[@TokyoEdTech]

I don't know how to explain it any better than I do in the video. If you share your code, I can take a look.

[@MH-yc5pr]

My python code does not recognize the term 'distance' Is it maybe because my version is a bit outdated and if so is there another word I can use to replace the term. Otherwise everything else works awesome! Thank you!

[@sriram-cj9pv]

It says that segments(the list) does not have an attribute "length".

[@vadymcherniavskyi9337]

I think that instead of not letting a player go in the opposite direction it's better to add this simple if else statement: def go_up(): if head.direction == "down" and len(segments) > 0: t.sleep(1) head.goto(0, 0) head.direction = "stop" for segment in segments: segment.goto(1000, 1000) segments.clear() else: head.direction = "up" so that if there are segments and you go to the opposite direction it just ends the game, because you've run into your body

[@Rwko.]

This is what happens anyways if you don't add the: if head.direction != "down": head.direction = "up" look at 3:27

[@kevilay]

I would like to understand how the segment clearing part being after the move doesn't cause a conflict. Because in your move() you place segment 0 ontop of the head. Then check for segments

[@TokyoEdTech]

As far as I know, you move the segments, then the head, then check for collisions. Check the order again to be sure.

[@johnbrowning1071]

When i add a segment the snake resets because the segment goes ontop of the head, how do i fix this?

[@TokyoEdTech]

Check the order of the code. Move the body. Then move the head. Then check for a collision.

i had the same problem and it's becasue your move() function is not in the right position it must be after the attaching the body segments but i've not understand why yet

[@firasjmii917]

so instead of dying when head hits the border i did this #when head hits the border it reappears from the other side if head.xcor()290 or head.ycor()290 : if head.xcor()>=290 or head.xcor()=290 or head.ycor()

The head has moved outside the border area and is switching back and forth. Instead of -head.xcor() use the actual number such as -290.

Hello, your videos are amazing! I just have a problem with my code, but I get no errors. The problem is that when the snake touches the food, I fail and the game restarts. But this didn't happen until I coded the head and body segment collision part.

You changed the movement distance to 15. That was not a good idea. The movement distance determines the collision distance. REF: head.sety(y - 15)

why on the top of my snakes's head is a segment and it has the same coordinates like the snake head,and everytime my snake eats it goes at 0,0. code: # Snake game # Snake Head 20x20 # Snake parts 20x20 # Screen 600x600 import turtle import time import random import logging logger=logging.getLogger(__name__) logger.setLevel(logging.INFO) formatter=logging.Formatter('%(message)s:%(asctime)s') file_handler=logging.FileHandler('register.log') file_handler.setFormatter(formatter) logger.addHandler(file_handler) logger.info("Jucatorul a intrat in joc in acest timp in jocul SNAKE") # Screen setup wn=turtle.Screen() wn.setup(600,600) wn.bgcolor("green") wn.tracer(0) # Snake Head head=turtle.Turtle() head.color("black") head.shape("square") head.penup() head.speed(0) head.setposition(0,0) head_direction="stop" # Snake Food food=turtle.Turtle() food.color("red") food.shape("circle") food.shapesize(1.2,1.2,1) food.penup() x_f=random.randint(-290,290) y_f=random.randint(-290,290) food.setposition(x_f,y_f) food.speed(0) # Snake parts parts=[] colors=["red","yellow","blue","orange","lightgreen"] # Border Line pen=turtle.Turtle() pen.penup() pen.color("black") pen.setposition(-298,298) pen.width(6) pen.pendown() for line in range(4): pen.forward(588) pen.right(90) pen.hideturtle() # Variables time_pause=0.1 distance=20 counter = 1 # Functions def down(): global head_direction if head_direction!="up": head_direction="down" def up(): global head_direction if head_direction != "down": head_direction="up" def right(): global head_direction if head_direction != "left": head_direction="right" def left(): global head_direction if head_direction != "right": head_direction="left" # Keyboard turtle.listen() turtle.onkeypress(down,"Down") turtle.onkeypress(up,"Up") turtle.onkeypress(right,"Right") turtle.onkeypress(left,"Left") while True: wn.update() if (head.xcor() > 290) or (head.xcor() < -290) or (head.ycor() < -290) or (head.ycor() > 290): head.setposition(0,0) for part in parts: part.hideturtle() part.setposition(350,350) parts.clear() head_direction="stop" if head_direction=="stop": head.setposition(0,0) if head_direction=="up": y=head.ycor() y+=distance head.sety(y) time.sleep(time_pause) if head_direction=="down": y=head.ycor() y-=distance head.sety(y) time.sleep(time_pause) if head_direction=="right": x=head.xcor() x+=distance head.setx(x) time.sleep(time_pause) if head_direction=="left": x=head.xcor() x-=distance head.setx(x) time.sleep(time_pause) if head.distance(food) < 20: x=random.randint(-290,290) y=random.randint(-290,290) food.setposition(x,y) part=turtle.Turtle() part.color("lightgreen") part.penup() part.shape("square") part.speed(0) parts.append(part) for index in range(len(parts)-1,0,-1): x=parts[index-1].xcor() y=parts[index-1].ycor() parts[index].goto(x,y) if len(parts)>0: x=head.xcor() y=head.ycor() parts[0].goto(x,y) for part in parts: if part.distance(head) < 20: time.sleep(1) head.goto(0,0) head_direction="stop" for part in parts: part.goto(1000,1000) parts.clear() turtle.mainloop() my code is a bit different.
