How to properly setup sceen so its scalable

Hello,
I checked few “guides” on how to setup responsive scene on all screens but not sure if they are correct.
I want to add cards on screen and i want sprites, images to scale up or down based on resolution.
So if i place omage in x:100 y:100 i want that sprite to be smaller or bigger depending of resolution. What is best approach? Can someone share game config?

It’s not quite “responsive” but I would start with scale mode FIT.

Hello Samme,
Will fit ruin resolution of images or make them blurry?

It can make the canvas a bit blurry. Scaling up looks worse than scaling down.

Thank you!
One more question, i noticed when setScale is used to make png bigger it will make that png blurry.
Should i for each bigger image use new image that is made bigger via photoshop instead of setScale?
What is good setScale use case to make something bigger without losing quality?

Can i make spine animations bigger/smaller with setscale?

Yes, you could make a larger source image in Photoshop so you don’t have to scale up sprites.

Yes, you can use setScale() with Spine sprites.
