Re: Giving the snake the bending effect

The genius thing about Snake is, that you don't have to move all the blocks every time. It really doesn't matter whether block 4 remains block 4 or if it will be block 5 later on.

All you essentially need to care about when moving the snake is, removing the tail (last block), moving the head and adding a new element behind the head. All the in-between parts never need to move. ;)

To change direction, you simply move the head in the given direction and add a new block where the head was before, it's very simple. But it's best to use a std::deque so you can work on both ends.

Exactly. Every segment except for the first and the last remain the same when you update the snake. Essentially, the update step then becomes:
  • Pop last segment (tail) from deque
  • Push new segment (head) to front
And you should iterate with iterators and not indices, because it's more generic and faster (for std::deque).
