Scratch

Sure!

Platformers are actually really easy to make, once you get the concept. I actually never knew how to and I eventually figured out. The main thing in a platformer is scrolling, i will explain that to you and more if you would like:

So the scrolling in a platformer is basically just 2+ images the size of the entire screen that seem as if they are connected. To make them scroll along side each other, you need to know the full length of the screen which is 480 in scratch. Now you know the length, how will they go side by side? Well, when you create a sprite the size of the screen, the x position will be set to 0. So the Sprite covers the screen at x 0. We will set the x position of the first image to be 0. The second image needs to be to the right of that image, so it will be the x position of image 1 + 480. The third image will be the x position of image 1 + 480 * 2 and so on. That is all there is to it! So to actually put this in work and test it:

1) Make a variable called ScrollX, this will be to move the images back and forth in the screen

2) Make three sprites that fill up the screen, maybe three colors (Red, Blue, and Black)

3) Create this script for the first image you choose, I chose red:

When Flag Clicked
      Forever
            Set X Position to ScrollX
      end

4) Okay, make this for the next image, I chose Blue

When Flag Clicked
      Forever
            Set X Position to ScrollX + 480
      end

5) Now make this for the final image, I chose Black

When Flag Clicked
      Forever
            Set X Position to ScrollX + (480 * 2)
      end

6) Now make a script to control the movement of the three screens.

When Left Key Pressed
      Change ScrollX by 3
end

When Right Key Pressed
      Change ScrollX by -3
end

Okay, those are the basics. (Sorry I just got back on scratch, I dont know how to use scratch blocks.) Test it out! It works right? In a platformer, you would replace the color images with separate backgrounds. If you wanted to loop back when you reach the end of the third image, you just have to reset the scroll x. Thats all! Everything else is pretty easy. The character actually stays in the same position, the only changes he makes depends on the type of platformer. If you would like more, just ask!    Here is a platformer i made: http://scratch.mit.edu/projects/itsmomito/1120339

      end

4) Okay, make this for the next image, I chose Blue

when gf clicked
      forever
            set x to <(ScrollX) + [480]>
      end

5) Now make this for the final image, I chose Black

when gf clicked
      forever
            set x to <(ScrollX) + <[480] * [2]>>
      end

6) Now make a script to control the movement of the three screens.

when gf clicked
if <(left v) key pressed?>
      change (ScrollX) by [3]
end

      change (ScrollX) by [3]
