Background for sidescrolling platformer

So say, you want to create a sidescrolling platformer, and level 1 you want to be, 1480 in width

Given the power of 2 rule, and 1080 X 1080 being the maximum recommended measurement for one scene, how are GS users approaching this?

Do I place 3 background layers that are say, 580 X 320 next to each other to create one long scene?

And are people just placing these scenes next to each other, and using camera movement only?

Or are you creating a rule, when X= negative half it's width, to adjust the scene accordingly?

Sorry if this is confusing! Just trying to get an idea of how GS users are approaching a sidescrolling platformer given the power of 2 rule

    Hey Butterbean, I haven't done a platformer yet, but from what previous posters have said, they just put multiple scenes next to each other.

    Where does it say that the maximum for the background is 1080 x 1080? Can we make it bigger.....will it just increase loading times?

    so actually its a 1024x1024 limit because the iphone doesn't handle anything bigger than 1024 in either dimension for the image.

    And the power of 2 rule is more beneficial to users because it rounds up to the next power of 2 per dimension even if to fill it up with transparent space.

    wait......wat is the next power of 2?

    So Codemonkey, you can still create 3 joining backdrops right, to loop the background and make on large one?

    ie: 512X320 (320 would round up to 512 anyway) so is it better just to create 3 adjoining backdrops that are 512 by 512, or can you create 512X320 side by side X 3 and still be okay?
  • Mr.pHMr.pH Member Posts: 26 the maximum of 1024 x 1024 for the scene size or a single image.......

    The max is imposed by Apple & has nothing to do with GS Software. It is per image. Anything larger than 1024 needs to be tiled. So you could have 3 in a row, or 3 up & down, or even 3 in a rows & 3 up & down, all at 1024 x 1024.

    I think I got it but I wanna be sure. I could have a scene that is a long side scrolling level that is 1024 x 4096 which means that i need 4 background images that are 1024 x 1024 instead of one large image.

    Correct, anything over 1024 x 1024 needs to be made into multiple images.
