So I have had a few stabs at a 2D scroller mainly following the tutorials in Dark Basic Pro Game Programming book, which are based on arrays and tiles and ahhh yes scrolling.

Take 1 - Load whole map in and scroll around.
Take 2 - Load part of map into scroll buffer and just reload parts as player moves.

But now I have read a few posts talking about using 2D planes with a 3D camera (not sure I get what that is yet, but that aside) is that the best approach for making a 2D scroller.

Ultimately should I be using 3D and cameras (an area I haven't looked at yet) for a 2D scroller?

Just want to know if that is the commonly accepted best practise?

I've found that using 3D is the best approach. Makes it easier to rotate the "sprites", scroll them, etc. I'm pretty sure that sprites are really just 3d plains. At least that's how it's approached in OpenGL. I'm not sure how DBP does it.

There are many advantages with 3D looking down on a surface. You can have realtime shadows, you can rotate the screen in a circle, you can have perspective. You have the choice to use 2D flat drawings, or 3D models. You have real parallax scrolling. You have real perspective. You can overlay a transparent HUD easier. And much more.

Thanks guys,

I wanted to do a scramble clone:

And although it is only going to be 2D it sounds like using 3D/Cameras has plenty of advantages to warrant going that path.

So I guess its time to read the 3D chapters in my book.

Thanks again.

A cool pro tip: When you use 3D plains to simulate images, use set object filter <obj> , 0

Get's rid of the blurriness and makes it look a lot sharper.
