Background Question

[sturmburg]

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.

[unikronsoftware]

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.

hi!
i get a issue with my background. The background over pose to my sprite when play the game prototype.
The Z axis of my sprite "the wall Stone" is 10.80086
The Z axis of my background is 52.88598
The camera i use is default of unity, Perpestive view
Soo...don't get what the problem here.

Can help me pls?
Thanks!

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

[xhidnoda]

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?

[unikronsoftware]

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

[xhidnoda]

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.

[unikronsoftware]

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?

[wagenheimer]

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

I must keep both?

[unikronsoftware]

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

[wagenheimer]

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

I must be doing something very wrong!

[unikronsoftware]

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.
