Hi,
well today i have another little question.

i will do a kind of a "Battelship" game. So i ha a Grid. I can also drag around the stuff i wont, but now is my problem, how i can save the "position" in a array?

Its more less like this:

1 2 3 4 5

2 x x x x

3 x x x x

4 x x x x

5 x x x x

so now i wont to now, object xyz is in quarter x/y (like 2 / 4)
then i will have to now, what is in this quarter. so do i have to do 3d array to save also "what" is in there? or is there a more simply way!?

thanks for all answers! :)

If I've understood the question correctly, I think you can do this with a 2 dimensional array.

Let's say you have a 6 by 4 grid

Create an array object and set the size x=6, y=4, z=1. Rename the array to be called GRID.

The data in your array will look like this (remember C2 arrays are zero based so the first row or column is 0 and the highest is (width-1):

x
012345
y
0 000000
1 000000
2 000000
3 000000

So now you want to put in a destroyer, which is 3 squares long, (and ship type 1) starting in the top left going horizontally. And a frigate (ship type =2) which is 2 squares long, starting in the bottom right and going vertically.

You can do this by creating actions:

GRID Set value at (0,0) to 1
GRID Set value at (1,0) to 1
GRID Set value at (2,0) to 1

GRID Set value at (5,2) to 2
GRID Set value at (5,3) to 2

Now the data in your array will look like this:

x
012345
y
0 111000
1 000000
2 000002
3 000002

And you can see what ship is where. You can also do error checking to make sure you are not placing a new ship where one already is, and update the values in the array when a ship gets hit.

Hope this helps.
