[AS Starling] Scaling : how to not scale assets ?

bali33

Hi guys,

I'm trying to figure out how to use Spine with different resolutions. Let's say I'm working on Spine with my 2x assets. In my application I will use 2x or 1x set of assets. In case of 1x I only need to scale down all my animation datas, not my assets because they are already at the right dimension. But when I use the scale SkeletonData property it will resize my assets too.

How I have to do ?

Thank you

If you used 2x in Spine you should use SkeletonData scale of 0.5 for your 1x assets. Why is this not acceptable for your scenario? Spine doesn't care about your actual asset size, it just draws them at the correct size.

Hi Nate,

I don't want Spine to resize my assets. My assets are loaded dynamically in order to fit with the device screen size and resolution. I don't want to load 2x assets when my application is running on an iphone 4 for example. It would be just loaded to heavy assets for this device.

Do you plan to add a method or property to scale animation properties but not the assets ? It would be very useful in order to optimize the memory usage and loading duration and performances !

In the Spine data there is a width and height for each region attachment. If you design in Spine with your 2x asset, these will be your 2x size (eg 200x200). When you scale at load time it scales the region width and height (eg using 0.5 the region becomes 100x100).

Again, Spine doesn't care about the actual asset sizes used at runtime. Whatever the asset sizes at runtime, they will be drawn at the size of the regions in the Spine data.

Hi,

Ok, I get it. So if my assets in 1x are 100x100 and I set the scale to 0.5 there will be display w/out deformations, is that right ?

Thanls

If your assets in Spine are 200x200 and your assets at runtime are 100x100 then yes, using a load time scale of 0.5 will cause your runtime assets to be rendered at their native size of 100x100.
