Dumb array question

I'm trying to script a system to create, display, and destroy "message box" type widows on the screen. The only thing is, I need to address each box as an individual object containing an x,y position. Now, how do I do this without using a multi-dimensional array?

You could sort of recreate a multi-dimensional array in one array, you just need to make the array twice as big as usual, and use some extra calculation while accesing it to seperate the x and y values.

a+b*c is the key.

what i do when i use 1 array for things like x & y you can ether put them side by side or at equal lenghts apart.... {x, y, x, y } {x, x, y, y,}

with the first one to acess the x & y its index = x & index +1=y

the second is index=x index+(lenght of first part of array)=y

I just do what Graal does offline in the tile selection window thing. Take this matrix, for example...

NPC Code:



      0   1   2   3   4

     

0     0   1   2   3   4

1     5   6   7   8   9

2     10  11  12  13  14

3     15  16  17  18  19

Those can be all the indexes, and you can treat them exactly like x,y coordinates. Just do row * 5 + column to get a specific index (start counting at 0).

NPC Code:



setarray XY,lenght;                            // define array

for ( i = 0 ; i < lenght * 2 ; i += 2){    // for loop with step of 2

  XY[i + 0] = Whatever;                      //  x value

  XY[i + 1] = Whatever;                      //  y value

}



// You could easily add as many variables as you like to an array this way.

This is basically how I do it.

I been using arrays for a long time. This works.
