is it possible to use sprites and then move the camera? or do I have to move all the sprites individual?

All of the sprites will stay in their respective positions on the screen, no matter where the camera is positioned. It is a complete different system. That is why some people use sprites for their HUD. However, I prefer to use locked plains...

hmm, ok, no camera then movement, then I have to move the all of the sprites (a lot of sprites, I paste them as floor tiles) I don't think that I can use plains for this game, they usually distorts in size, it has to be pixel perfect sprites.

yes, as far as I understand, then you can only use the camera for 3D, and when you program sprites you have to move all the sprites (nothing the camera can do in 2D)

There's a couple of solutions for this,

1. Write your own Move2dCamera() function. The theory behind it is that you take all active sprites and move them opposite what you tell the camera to move. And if you want the camera to zoom in closer to the "ground" then you just make all the sprites bigger and move them away from the center of the screen.

2. Use 3d plains for sprites, Highly Recommended! Mucho faster, plus you get camera functions.

right now, the last sprite loaded is the one that is on top of the others, is there another way to decide which sprite is the top most?
(I want a sprite to be over other sprites)

What you want to do is set up a system of layers.

Background
terrain
moving sprites
other

Categorize each of your sprites into these layers, they are drawn in that order so that Background is drawn behind everything, then the terrain (grass, dirt, etc.), then all the moving sprites can be placed, and if you want stuff to be on top of the sprites (like a tunnel or something) use the "other" layer.

I have discussed this in the 2d topics, and I will just load them in the order they should be (floor tiles first, then the things on top of floor tiles, then player, etc etc)

Good idea

Also, if you decide to make some camera functions, make them for both 3d and 2d. That way, you just have to use the once command
