Im a bit confused about the usage of cameras in a 2d enviroment.

It doesn't appear that most of the commands related to cameras that normally work fine in a 3d enviroment, in particular when it comes to following objects, or controling the camera itself work the same in a 2d enviroment.

For example there is no "Cammera Follow Sprite" command.

If i create a sprite and set it up to control it using arrow keys how would I get the default camera to follow the sprite?

Unless you are working with 3D specifically there is no camera.

In 2D, you just have a grid of dots (pixels). You place/move things on there to give the impression of movement - like scrolling.

Although the 2D screen co-ordinates run from 0-799 and 0-599 in 800x600 screen mode, you can still use values outside these ranges to place things (images/sprites) off the screen.

Just think of the camera being locked in place and instead of moving the camera to point at objects, you move the objects into the view of the camera.

If you want the "camera" in a 2D environment to follow a sprite, then you might consider moving the environment, and keeping the sprite centered.

There are lots of posts and snippets about scrolling terrain or backdrops, check 'em out!

There is no 2d camera built into DBPro, unfortunately.

So... a 3d camera rotates, pans, and zooms. The easiest (and fastest) 2d camera to make, would be one that pans. Left/right, up/down. You would just take your object's "World" coordinates, and subtract them by your camera coordinates. A bit harder than this would be adding in scaling. You would multiply the object's world coordinates by a scale factor, and then subtract them by your camera coordinates.

Even harder, adding in rotation. That involves rotation matrices, and trig. Basically, you take the object's world coordinates, rotate them by the negative camera angle, scale them, then subtract...

I wrote some code to do just that in the code snippets board.

It's kinda slow though, and I've only tried it out with circles and lines.

Still, i'd recommend simple movement, from side to side. Rotation and scaling doesn't seem to add much to a 2d game (rotation especially)
