2D Objects in 3D world

Hello.
I’m beginner and trying to make a game where 2D objects live in the 3D game world.
At first, I added a 2D objects into my 3D game project according to this tutorial (Beginning 2D Game Development - Unity Learn), but in this way, 2D sprites had 3-dimensional appearance, like Quad primitive, and that was not i really wanted to do. I want 2D objects to show us the same shape, regardless of camera direction, even if I looked at the 2D objects from the direction that is pararel to the plane where 2D objects are lying.

So my question is: (1) Can I make the setting like that? abd (2) if it is possible, what should i do?

I’ m sorry for my poor English, because my mother language is not English…>_<

hey;
language was good ;
u can do it easily ;

specially unity makes it so easy to work with 2d and 3d together;

u can do what u want u just need to assign a code to your 2d objects and make them to always look at the camera;

this way any rotaition to camera makes no difference to 2d object cause they are always facing the camera :

so u can use code like:

transform.LookAt(Camera.transfomr);

or any thing else u may need little modification too;

good luck;
