Hey guys so here's my problem, ive copied more or less what ive seen from Pizzaman's 2d tile guide(dont remember the link) and im trying to get my map to be drawn according to the 2d Array.
This is what it looks like at the moment.

#define a 1 //air tile
#define r 10 //restriction tile

//On display it shows ROTATED 90 DEGREES TO THE RIGHT
int map[ROWS][COLS] = 
{
	{r, r, r, r, r, r, r, r, r, r, r, r, r, r, r, r, r, r, r},
	{r, r, a, r, a, r, a, a, a, a, a, a, a, a, a, a, a, a, r},
	{r, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, r},
	{r, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, a, r},

};

And this will give me this output

as you can probably tell its reading the array 90 degrees to the right

When this is done in DB Pro with data statements the display is different.
With this code

This is the result

Which is what im TRYING to achieve, i dont want to have to write my map at a 90 degree angle as it will be a nightmare.

All im trying to do is to get the array to output those values the same way the data statement does

this is how im currently displaying the array

+ Code Snippet

   for ( int y = 0; y <= 15; y++ ) 
   {
      for ( int x = 0; x <= 20; x++ ) 
	  {       
         dbPasteImage( map[x + tilenumx][y + tilenumy], ( x * tilesizex ) - tempx, ( y * tilesizey ) - tempy );
      }
   
   }

The code is pretty much the same for both versions.
Please help me out

Quote: "map[x + tilenumx][y + tilenumy]"

the first part of an array is the "y" value. You have transposed the x and y.

The fastest code is the code never written.

Hawkblood by changing that like you said it does work, but screws up all of the collision big time, i found another way by making a temporary array and copying the contents of that to my map, and its working thank you for your help.

doing what Hawkblood said is more efficient, with large arrays it could get slow, and that is not even necessary, better change the collision code, perhaps you are flipping the x and y there too, so it could be simple to fix

Hm i see what your saying Hassan, i spent a fair part of the night trying to fix that, for now i think i'l just leave it and when i'm done i'l go back to try and write more efficient code.

Thanks

Believe me, you don't want to rewrite code when you are finished.... The further you get in your program, the more integrated a problem becomes and the more work you will have to do to change it.

The fastest code is the code never written.
