How to create high-quality 2D animation?

Question

Game development

I often see people create beautiful animations in DragonBones, Spine and other programs.
I also decided to try this. First, create a simple animation. And immediately ran into a problem.
Right now I'm using GameMaker Studio 2 Desktop and DragonBonesPro. I create an animation in DragonBonesPro and load it into GameMaker Studio 2. And I have a problem - bitmap distortion.

Setting the Interpolate colors between pixels option in GameMaker Studio 2 improves the animation quality, but still some problems remain.

As I understand it, this is not my fault. The reason is raster graphics.
The fact is that DragonBones does not export vector graphics. That is, the output will always be texture atlas (png picture with all animation image elements).
So we need vector animation. And where to create it?
Even Spine doesn't let you do that.
And this is only part of the problem.
Even after creating such an animation, how to load it into GameMaker Studio 2 Desktop?
Here is a list of supported files.

I'm advised to flash, but it's unreasonable to create animation for games there and refuse all DragonBones, Spine chips.
These are professional tools. I am sure that many studios use Spine and create high-quality animation.

Answer 1

Don't use GameMaker Studio, I tried, didn't like it, too many restrictions.
And the syntax there is generally "magic". Assigning a value to a variable will change the variable for all objects of this type and other absurdities.
Better switch to Unity . It's already a classic.
As for vector graphics, it is practically not used. I can’t say for sure, but according to my ideas, drawing an arbitrary polygon with 10 vertices on the screen and coloring it will use more computing resources than copying the finished image from memory. That is, theoretically, vector graphics can give a gain in build size and occupied RAM at runtime, but it increases the load on the smartphone battery and increases the minimum system requirements for the game (except for memory).

Answer 2

As I understand it, it's not my fault. The reason is raster graphics.

Well, yes, apparently, it's your computer that spoils the graphics on purpose.
1. You need to increase the resolution (depth) so that you have not 1 pixel per inch, but, for example, 500.
2. Use anti-aliasing. It was specially invented for the "jagged" effect.
3. Sub-pixel rendering.
4. You can draw all the parts separately, create a skeleton, attach your parts to the skeleton, animate it, and then render it to an atlas.
In any case, vector graphics do not exist as such, it is just an intermediate format between the artist and the monitor. You still have to draw your graphics on a pixelated screen, regardless of its format.
