Well, i know that there have been a lot of posts on this, but as much as I search through the forum and read the multiple array tutorials available, I just dont understand how it works with snake, and how i would go about creating a snake game.

Its for a school assignment, and I would really appreciate it if anyone could help me out, not tell me the answers, but send me in the right direction or w/e.

would be really appreciated if someone could help.
Thanks a lot cheers!

Multiple arrays? You mean, multi-dimensional arrays? If so, then yes, you will need those to store the environment that your snake interacts with. Generally, a 0 represents an open space. A 1 would represent a wall.
Your snake should be a flexible array (because he can grow!) of a record that records x and y components.
You'll also need to keep track of the snake's direction. Just use a global variable for that.

I think that should "send [you] in the right direction". On the other hand, you could have already gotten that and are wondering, say, about how to get the segments to follow each other. I don't know, because you haven't specified. If you want help, you're going to have to specify.

code:
var arr : flexible array 1..1 of type


If you want to add dimensions

code:
new arr, upper(arr)+1

You're in luck!

And Mystic, that does not add dimensions. That adds elements. 8)
Lastly, can you please tone down your sig? It's rather long.

Okay im making some progress with this game.

I finally understand this whole flexible array thing, and i got the outside collision detection, but the self collision is what I cant figure out.

code:
exit when whatdotcolour (snake (1).x, snake (1).y) = red


Ive looked at the Worm game posted in 1st reply, and it seems to work there, but its not working for me, and I even tried to duplicate that set of code, and it still doesnt seem to work, any help is appreciated Very Happy

For snake, you shouldn't be using whatdotcolour. It just complicates everything. Snake works on a grid system, so, you don't need to worry about checking ranges of values. It's just a single point comparison. Do you know how to use 2D arrays? (check the Tutorial section, if not!) I recommend you use one of those for your map, and fill it with integers (or strings, w/e) that represent different things. ie. 0 = empty, 1 = wall, 2 = apple. Then just take the x and y position of the snakes head, plop that into your grid array (like this:
code:
if grid (snake (1).x, snake (1).y) = "2" then  %you ate an apple!

) and voila, you've got your collision detection.

SOrry for the double post.

This is really starting to bug me. My teacher says i cant switch games and this assignment is due friday and worth 25% of my mark, and its just killing me that I cant even begin this, its really agravating.

If someone experienced could please help, i basically am a total noob at this. What we learned in tech this year was not enough for me to gain the ability to code this game, and i am just really lost.

anyone, plz help. thanks alot Sad
