Title: Background Question
Post by: sturmburg on April 29, 2013, 02:12:03 pm

Hi,

New to 2D toolkit and had a question about backgrounds in a side-scroller.  If I have a single image I want to use as the background, what is the most efficient way of displaying it?

thanks for any info.

The most efficient way to do this is likely to use runtime sprite collections. Check sample #13 for more info on how that works. This is to avoid having to create an atlas or anything else.

Well you didn't say you used a perspective camera :)
Have you tried calling MakePixelPerfect on the sprite after you create it?

thanks for reply to soon :)
I am in my work now, in the night i see the MakePixelPerfect is check o create.
This issue only happen in 2D toolkit 2.0 not in 1.9 version.
Unikron...can you says what camera is more recommended for game 2D?
In my case i use camera default of Unity and perspective, because i get a parallax effect whit my background and my sprite on front.
can you?

If you want to use a parallax camera, thats fine, but you just need to call MakePixelPerfect once. The checkbox is not present in tk2d 2.0, but all you need to do is click "1:1". As long as you don't move it in z then it will always be fine :)

yep..clik the 1:1 is a option to solved this problem...but destroy all scale of my sprite.
So for now a set the camera the "far" value to more!
Thanks!

Hi,

I'm also new to 2D toolkit. If I have a single image I would like to use for my background, how do I set it up?

Thanks.

In 2D Toolkit 2.0, select the background image in project window, and in hierarchy window, Create > tk2d > Sprite from selected texture. Set up the camera settigns and you're good to go.

And there is a way to resize the background to it's original size?

My background is 1280x720 (My camera also has this size)... But when I create a sprite from it, I got a 1024x512 texture.

How to resize it easly to it's original size and make it fits all my camera view?

And why it's create on my scene a Sprite and a tk2dSpriteFromTexture - background01?

I must keep both?

Yes. One of them is the sprite collection. It gets deleted when the sprite is deleted.

And the other question about the Original Texture vs Sprite Size?  :)

I must be doing something very wrong!

That sounds very much like your texture importer setting is set to "Texture" and not "GUI". Set it to GUI or manually enable non-power of two textures for it to be the correct size.
