Just out of curiosity, I'm not working on anyrhin 3d, how would you do a 3d tilemap matrix, ex. a

3 x 3 x 3

?

I'd use a 3 dimensional array.

AE.

Oops, I worded that wrong. I kinda meant how you programmed a 3d array.

By the way, where did you get that animation?

Here's an example:

I believe this is more accurate:
int map[DEPTH][HEIGHT][WIDTH];

With arrays you have to use inverse of what you want (for optimal memory access that is).

So how do you do a tilemap w/ a 3d array?

By letting the array elements denote tiles.

But with the numbers denoting tiles.

IHBT, IHL, HAND?

which are?.?.?

I think gnolam is wondering if you have the faintest idea of what you are talking about.

I haven't done anything 3D before. Besides, you're not gnolam. Gnolam can speak for himself.

I'm simply wondering if you're trolling or if you really are as thick as you appear to be...

Yes, but I get the feeling that it would have to be censored.

Well for starters, you don't use tilemaps in 3D graphics. A 3d tilemap array is something different. It allows you to add layers to 2d tilemaps so that you can do things like 'fake 3d' games, and animated tiles.

So you have a 3D array, right? It can be an array of ints. You loop through it, just as described by LennyLen. Each int can hold say, 1 or 0. 1 is for a tile, 0 is for no tile. Assuming you have a bitmap/model representation for the tile, you could do something like this.

    for( z = 0; z < DEPTH; z++ ) {

        for( y = 0; y < HEIGHT; y++ ) {

            for( x = 0; x < WIDTH; x++ ) {
                if (map[x][y][z]) {
                    DrawTile(x, y, z);
                }
            }
 
        }

    }

That's a very simple tile map. I'll leave it up to you to decide how DrawTile is implemented.

[edit]
It's a good idea to figure out what something is before you ask for help on how to implement it.

You could still design a 3D level by using a 3D array to represent which blocks appear at certain discrete locations in 3D space (gap, brick wall, metal wall, etc.). You'd be using blocks instead of tiles, but you'd be using a 3D array like you would do for a 3D tilemap.

3D tilemaps are probably best sed for 2D games where the tiles consist of several layers (eg. what lies under the floor, the floor, the walls, and a transparent ceiling).

This has nothing to do with anything in the topic thus far, but I get this error message when I run my code in g++:

error message:

maptest.cpp: In function 'int _mangled_main(int, char**)':
maptest.cpp:27: error: expected initializer before 'bmp'
maptest.cpp:50: error: 'x' was not declared in this scope

code:

I stand by my previous comment(s).

Which ones?

He's wondering if you're trolling.

No.

[edit]I found a few reasons for a few of the bugs, and cut it down to specific code. Now the error is:

maptest.cpp:26: error: at this point in file

the code is: (starting line 10)

Try using load_bitmap() correctly.

And check the manual if you have any questions on how to use it.
You can click on it in the code you posted for a quick link.

I've read the manual, here is my new error and code:

maptest.cpp:36: error: expected primary-expression before 'palette'

Try this instead:
bmp = load_bitmap("Woodland_Tileset.bmp", Null);
You don't need the palette since you don't use 8 bpp graphics.

It says "Null was not defined in this scope"

Try null instead. (lowercase N)

I got it! NULL

wait...it isn't working! No errors, just not working!

It works, I think. But you are not waiting for the user (you) to press a key or click the mouse. What this piece of code does is to set up a window, draw stuff to it and then quit.

You only blit the buffer to the screen once when you start the program, but never again after updating the buffer.

The window just flashes and quits. How do I fix that?

Wait for a keypress or something?

It doesn't work
