2d game how do you creat desired game objects ?

Hello everyone, I stumbled on a problem that I can't google out. I want to know how to make 2d game objects, for example I would like to add a half of a circle as a game object, but I can't find where or which software to use to creat my own. Would be very happy to find out and would like a beginner friendly explanation.

 

I would suggest G.I.M.P for your 2d image needs, create it, save it and import it like any other image.

 

Any 2d software ya like. I like Paint.Net but I'm not a big artist.. But it works for me, when I do use it.

 

I'm fond of Adobe Graphic for vector drawing, and Affinity Photo for painting. But as others have said, use whatever you like. Unity doesn't care.

 

Create a half circle in any paint tool, make sure the background is transparant.
In Unity, create empty gameobject > add Spriterenderer > Add your image to Spriterenderer.
After that you can add a collider if you need it to collide (for a half circle you could use a polygon collider).
