Simple tile engine.

Hi all.
After i failed with my 1st game(well you can take a look at "game programming section") , im about to start a new game.
But this time i'll start by collecting information.
1)How can i design a simple tile map? and how can i save&load the position of every object from a file?.
In my non-finished game i was loading the data like this:
the output was something like this:
xxxxxxxxxxx
xxxYYYYxxxx
xxxyyyyyyxx
xxxyyyyyyyy
xxxxxxxxxxx
I learned that its better to use 2d arrays.
Whats the right way to do this?
2) And a last question,
how can i detect collision?
thaNks!!edit:
Im working with SDL & C++..if that helps!!

for array I use
myclass *DATA;
or
int *DATA like in your example
then
// create data buffer
DATA = new[width*height];
x,y data is
int value = DATA[y*m_width+x];
or
DATA[y*m_width+x] = 1; // or any other value U use
and don't forget to
delete []DATA;
to release memory.
In this example you can use any width and height you like not just 512, 512 like in your example, and with this you are saving a bit of memory.

Nice , thanks.
And how about the indexing?
I have the feeling that by just updating the array with the path x & y , wont work.
There must be a conversion from standard x,y to tile x,y. right??

i have done my own simple tile engine like i load nums of images from tileset from file to vector like this(file):
0 1 1 2 1 1 0
0 0 1 2 1 0 0
0 0 0 2 0 0 0
then i convert it from vector to [mapx][mapy] array
and now i only draw it to screen in loop and adding camera poses.
i never read anything about how to program this, its only come from my head and its working :p
0 1 1 2 1 1 0
0 0 1 2 1 0 0
0 0 0 2 0 0 0

Can you post a small example how you load/save them?
ehm, what save load? :p
load map from file?
and this draws my map
and thats all
dont use it, made by noob :pp
load map from file?
void LoadMap(int i){ vector<int> file; int data; char path[128]; sprintf(path, "Data/map%d.txt", i); ifstream in(path); while(in >> data) file.push_back(data); for(int i=0, x=0, y=0; i<MAPX*MAPY; i++, x++) { if(x>MAPX-1) y++, x=0; map[x][y] = file; }}and this draws my map
void DrawMap(){ SDL_Rect tilePos,tile; tilePos.w = Tileset.tilesize; tilePos.h = Tileset.tilesize; tile.w = Tileset.tilesize; tile.h = Tileset.tilesize; for(int x=0; x<SCREEN_WIDTH/Tileset.tilesize; x++) { for(int y=0; y<SCREEN_HEIGHT/Tileset.tilesize; y++) { tilePos.x = x*Tileset.tilesize; tilePos.y = y*Tileset.tilesize; tile.x = map[x + (int)Camera.x / Tileset.tilesize][y + (int)Camera.y / Tileset.tilesize] % (Tileset.tilesetsize / Tileset.tilesize) * Tileset.tilesize; tile.y = map[x + (int)Camera.x / Tileset.tilesize][y + (int)Camera.y / Tileset.tilesize] / (Tileset.tilesetsize / Tileset.tilesize) * Tileset.tilesize; SDL_BlitSurface(Tileset.image, &tile, screen, &tilePos); } }}and thats all
dont use it, made by noob :pp
Check out the articles section here on Gamedev. I found this one pretty quickly.

Ack! Change the include <*stream.h> to just <*stream>. Someone needs to change that.
