Making a Snakes(Clone)

Nabeel · 12-28-2012, 01:48 AM

Well I'm making a snakes clone. And this is what i've done so far. The language i'm using is python and as you can see i have laid down the basic idea of the game BUT I can't understand the basic logic of making it MOVE like an actual snake. So Please If an one can explain how that is achieved and how to implement it!

Treat each segment of the snake as its own physics entity (that is, position+velocity you update each tick). Maintain a list of points where the snake turns, and the direction it turned to. When a segment reaches a turn point (equality with some fudge factor because of floating point), change the velocity to what the turn point indicates in the list. When the tail of your snake gets to a turn point, remove that turn point from the list.

What I understand from your advice, This is how I precieve it.

* each part of the snake is to be drawn as a seperate entity.
* The player will control the direction of the snake's head and its velocity will be passed to the next part with each tick.
* The turn should be applied to each part seperately.

Please provide a suggestion if you find a flaw among the above. I might as well switch to classes to deal with specific parts of the snake.

I don't know python and this might be a stupid idea, but I would probably implement the snake as a (cyclic) linked list of coordinates. You remember the pointer to the "head" segment, when you move, you replace the "tail" segment with the new position of the head ("head" + "velocity") and set the head pointer to this new segment. If the snake grows, instead of replacing the tail with the new segment, you will insert the new item before the "head" and set the "head" pointer there.
