How can i get runtime vertices in 2d animated sprite?

Unity Engine
1

Hey guys,
I have a sprite that was animated by adding bones and geometry with 2D animation version 2.0.0. The sprite is animating great and now i want to add collider to my sprite. But i find that the sprite.vertices are not updated during runtime, which are the initial vertices of the sprite.

How can i get the vertices positions during runtime?

Thank you for your help!

It is not possible with the version of 2D Animation you are using unfortunately.

We will expose this in a future version.

Up, is it now possible?

https://docs.unity3d.com/Packages/com.unity.2d.animation@4.2/manual/SpriteSwapIntro.html I think this is it.

Yes, it is possible now in 3.2.2 for 19.3 and 4.2.4 for 20.1
via SpriteSkin.GetDeformedVertexPositionData()

We do not have any examples of this. Could you share with us where you are currently stuck @stickylab ?

Hey,

Just tried to get vertices with GetDeformedVertexPositionData() in Update method and assign positions to test spheres: spheres moves in another direction than sprite with real vertices. How can I get global vertices positions?

Solved. It seems that GetDeformedVertexPositionData() returns localPositions relative to SpriteSkin’s transform. Perhaps this should be reflected in the documentation
