`As I said nickel, think along the hall, up the stairs and round the corner.`
```
```
Kif you put your hand on the table in front of you, you can move it left to right, that is the x axis and that coordinate is first, you can move it towards you or away, that is the y access, and indeed the two form across, and that is all that is needed in a 2D game.
```
```
however, you can also move your hand up off the table and put it back down. that is the z axis, and is used in a 3D game.
```
```
So, you could have a point 5 cm along the the desk, 3 cm forwards, and 2 cm avoe the surface of the desk, or as coordinate 5/3/2.
```
that is how 3D and 2d coordinates work.

Hth.

Beware the Grue!

```HI Tom
I also battle to understand coordinates.
What's the difference between the line running from left to right and the
line running from front to back?
Isn't the two  the same?
```
If I have a line from left to right and a line from top to bottom, it makes
```a cross.
But how does a line from front to back looks like?

Hi Damien,
I see. Well, that's certainly understandable. Although, it is nothing
less than a crime that your primary school didn't properly educate you
when you were young. That's there purpose regardless if you are blind,
sighted, stupid, a genious, whatever. It is not up to them to decide
who does and does not get a quality education. What idiots.
That's just predgudist what they did to you in my book.
Anyway, fortunately, understanding coordinates isn't really that hard
to learn. It is a pretty straight forward subject and I could describe
it in a couple of para graphs. Think of it this way.
You have a line running from left to right or east to west. This line
is your x axis of movement. Now we are going to draw a line from front
to back or north to south. This line of movement is going to be our z
axis. Finally, we are going to draw a third line running from up to
down or top to bottom. This line will be our y axis. So now what you
have is three different coordinates x/y/z which provides you six
directions of movement in any direction you need to go.
So if you press the c key in a game and it says something like 15, 11,
22 that means you are 15 units east of the west wall, 11 units above
the ground, and 22 units north of the south wall. Does that make
sense?

Cheers!
