Camera default values don't make sense

Hey everyone,

I'm experimenting with moving the camera to scroll a TMXTileMap in Landscape Mode.

When I get the values for the camera using this code:
```
float x, y, z;
[self.camera eyeX:&x eyeY:&y eyeZ:&z];
```
The values for x & y are 160 & 240 respectively. This is fine as it is the center point on the screen. I understand that.

However, when I adjust eyeY and centerY, the map scrolls in the direction of the narrow screen width. This tells me that the 160 should have been associated with the y value.

Does this make sense to anyone? Please explain it to me if you can.

I thought I might follow up on this post as it continues to mess with me.

If you look at this picture:

You will see a blue square centered at the default eye position.

My question to this is why is it not in the center of the screen?

For landscape mode you have to modify the x and y coordinates:

[self.camera setCenterX:p.x-80 centerY:p.y+80 centerZ:0];
[self.camera setEyeX:p.x-80 eyeY:p.y+80 eyeZ:415];

Does anyone know a place where I can look up the codes for posting code properly and how to use them?

@MikeHart: Thanks a bunch for mentioning the whole landscape requires and offset. I figured I must've been doing something wrong... much appreciated!
