  1. Sir…This program is raising "in_incrementudc raise Terminator Turtle. Terminator" error ….Plz help.

  2. (THIS IS NOT AN ERROR SO please try answering it here] i dont understand the part where u adding those tail segments in reverse order… the part where u write segment[index].goto(x,y). So if u want for example, segment 5 to follow segment 4, and u write this, shouldnt it overlap? becuase thats what i understand. Or does it mean that the loop is so quick that by the time the 5th segment replaces 4th one, the 4th one already replaces the 3rd one and so on? and also the special case for the first segment to follow the head, so how doesnt it just overlap the head and manage to go behind it? pls try to answer i really want to understand how this works

  3. hii bro this line (for index in range(len(segments) – 1, 0, -1): ) in my laptop the erroe is coming
    saying that
    Traceback (most recent call last):

    my segment ( the grey one) appears when i start the program

  5. 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)

  6. Hello, nice code but when the head catches the food the game becomes laggy

    Thanks again

  7. Hello, thanks for this helpful tutorial but I really didn't understand the code after 3:40, you explained it very fast :/

    Why did you put a "-1, 0, -1"?
    is the x/y coordinate just (amount of segments -1)?

  8. bro plz help when i run this program till #move where the head is part when i run it and press the keys w,a,s,d my snake doesn't move plz solve it as soon as possible

  10. Is it possible to keep some space between each segments?

  11. is there a function to say if snake goes left the snake body has img… if snake goed right the snake body has img….?

  12. it shows me the grey segments but they arent at one shape with the head they are just some grey squares at the screen frozen
    thats my code

  13. how do i add another food object that make the body segment loose 1 segment when consumed.

  14. #error new_segment = turtle.Turtle() doesn't work error on the end of this command

  15. your channel is very cool and nice but the square is only one square Why?

  16. after i run it .. i cant move anything like it dosent move

  17. when the snake eats the food there will be a new segment but there's a trail following it for some reason pls help idk if i missed something

    edit: nevermind i found the problem, i forgot the penup lol, thanks

  18. this is the error i get pls help me

  20. Hi! So it looks like I'm having an indentation error and I think thats because, before nothing would move and I was pressing stuff trying to make it work, but anyway, if you see something other then an indentation error, that would help me alot. Thanks! Here's the code.

  25. When I eat the first apple the application crashes

  26. bro please help me. my snake is getting bigger without eating. it just keeps on going

  27. Did you remember to put the functions video in the description ?

  28. Hi, my problem is that it keeps on popping up with a message saying 'unindent does not match any outer indentation level'. I'm not sure what's wrong with it.

  29. So so so detailed and I love the way you break a game into bite-size chunks so it's easier for ADHD-affected people like me!!!!!!!!!!!!!

  30. the parts are divided so incredibly insightful – different part of the games and it is explain with so much details!

  31. you are a fantastic teacher, thanks so much for this series

  32. it always crashes instead of the snake getting longer please help

  33. pls help me
    "Unindent amount does not match previous indentPylance"

  35. I really like your tutorials. However, while I sort of understand whats going on with the snake body, i probably wouldnt be able to apply this logic in another project if needed. I am not sure if im stupid or just still inexperienced cause i dont see myself coming up with this at all at the moment. Makes me want to abandon this tutorial as I have not understood everything fully and feel im just copying the code. i dont think its your fault though. I just dont get the logic behind the snake body (yes ive read the explanation youve given somewhere else in the comments)

  36. this is the first episode I didnt 100% understand the logic, the body is confusing

  37. Sorry for asking for help again but I have a bigger problem. when I collide with food the game resets.

    here is the code I hope you can help me:

    the identations are correct but copying and pasting put it all together

  38. I need help. When I start the game, my snake keeps creating more segments. Is there a way to fix this?
    Please help me out by replying to me.

  39. I need help again. So on my python code it says invalid syntax.
    The problem is that i don't know what that means.Here's the error,

  40. hi i have a proble when i eat firs food segment 0 instead of going to the end of head it goes to the same place where the head is

  41. I have an error its this: for index in range(len(segments)-1, 0, -1): type error object of turtle has no Len()
    here code

  42. I'm having a little problem with getting my snake to grow bigger. I was making this snake game on my own but i ran into a phew problems so I decided to look for help. If you run the code it actually does get bigger but for some reason the snake body part changes its color to the head part. By the way i really enjoy your tutorials and I've learnt a lot so thanks! Here's the code https://pastebin.com/N6nLtdAR

  43. Hii. Right now my game starts with both "head" and one "segment". I wonder how I fix so that the game starts with only the "head"? Here's my code (I've added the function def tran() btw but that doesn't cause the trouble I think):
