Snake game, can't add new rectangles?
- by user1814358
I had seen some problem on other forum, and i tried to solve them but unsuccesfully, now is too intersting for me and i just need to solve this for my ego... lol
Main problem is when snake eat first food, snake added one rectangle, when snake eat second food nothings changed?
When snake head position and food position are same, then i try to add another rectangle, i have list where i stored rectangles coordinates x and y.
What do you think, how i can to solve this problem? I think that i'm so close, but my brain has stopped. :(
