Here is a demonstration of how I plan the tiles in each level to load and unload.

Sick vid



I plan to draw every rectangle in the level at load. Then programmatic decrease the x coordinate. When the rectangle reaches the right edge of the screen the sprite will be drawn inside it. It continues to move until it is no longer in the viewport then disposes of it.

This is the easiest way, and least memory intensive way I could think of how to do it. Any suggestions?

P.S.
I was going to use an array of rectangles, and when the got off screen reuse them, but that would limit the amount of rectangles allowed on screen. Or it would be too big and take up more resources.

For a 2D game on modern hardware you really don't need to worry about memory or CPU intensity. Focus on keeping the design simple instead.

You can always optimize it later but you can't always un-complicate it.

Does your idea involve not being able to go back to the left, like in Super Mario 1?

God I hope this isn't like one of those levels where it auto-scrolls and if you stop it pushes you and you either get crushed or fall off a cliff... those levels always pissed me off

Once you get 2/3 of the screen it will start to scroll, but if you're idle it will not. And, I don't plan for them to be able to go 'back.' My main concern is that this isn't Counter Strike or Gears of War, so I figured people would like multi-task with it. That is why I wanted it to be [somewhat] light on resources.

How'd you suppose I make it simple? With the array idea?

It's 2D. It will be light on resources until you add some crazy post-processing graphical effects. There's really no other option.

Yeah arrays are pretty simple. What are you making this in again? There might be a "collection" -like data structure better suited to sticking all these objects in. You should be able to add and remove them easily, ideally.

Or just load them all into one big array when the map loads.

The problem is I need to know all the tiles' positions before hand. So I would need a multidimensional array of the positions, then an array of rectangles to draw them. And I really hate arrays.

Hmm...I guess that wouldn't be too hard.

Here's an idea:
Say I do the same as above but with a multidimensional array. I read from the level file the positions of the tiles (which are limited to 64x64, so I only need x and y), then slam them into the array. Then when needed I add a value to each x of the array to simulate movement. Check to see if the x is at the edge of the screen, if it is use a recycled rectangle (from an array of rectangles.), and throw a sprite on it. Check to see if the rectangle is still in the viewport, and if it is not then recycle the rectangle and sprite.

Sounds like you need classes son!

Seriously, that would simplify everything SO MUCH. Make yourself some kind of Sprite class, the extend it for the player character and so on. Does C# have multiple inheritance? Some half-remembered thought says "no!" but I don't trust it

I know I need classes. And no, you cannot inherit from more than one class. I jus' wanted to know if that idea sounded on cue.

You've got the right idea. I think it would be easier to move the screen though, rather than all the blocks. Just have the screen.x go from 0 up and draw the blocks only if block.x - screen.x < screen.width.

Or something similar.

That wouldn't move the screen position would it [like across the desktop]?

No. By screen.x I mean the in-game representation of the screen. Or the area in the game which is currently shown on the screen.

Anything that "area" contains or touches should then be drawn.

That way you can just move one object around and have it look like everything is moving.

In that case I will jus' draw all the sprites....no that would increase load time. Eh, we'll see. I also have to see if I can do that with the viewport (in XNA viewport is equivalent to screen) [that is move it I know it has an x value].

The XNA Viewport is literally the window for your program.

I probably should'a been more clear but I mean a "viewing area" inside your game world that can move. So for example:

code
+----------------------+=====================+--------------------+
|                      |viewing area         |                    |
|                      |             +---+   |                    |
|                      |             |   |   +--->                |
|                      |             +---+   |      (stuff out    |
|     +---+            |            /        |            ahead)  |
|     |   |            |    visible block    |                    |
|     +---+            |      0              +--->                |
|    /                 |     /|\             |                    |
|   not visible block  |     /|              |                    |
+----------------------+=====================+--------------------+
                 /
              the entire level


The just draw the stuff that falls withing the "viewing area" as it moves. If that makes any sense.

Hmmm, I seem to have forgot that the draw method allows a vector2 or a rectangle. So all this need for rectangles....

Point = no need for rectangles.
