Question by Firedan1176 · Jun 04, 2015 at 06:32 PM · 2dsprite

Possible to draw a filled circle 2D from code?

I need a circle to grow in size from small and over time can get really big, but I would prefer it not to become too low resolution for when you get closer. Is there any way at all to create a sprite that is a filled circle from code? Or should I just create different sized circles (256, 1024, 4096) and switch between them when it gets large?

Hi Firedan,

I think the best way to accomplish that would be to make an animation for the circle. The quality of the sprite will determine the definition when it is big and you would need to have only one sprite.

Here I left you a really simple example I've made with the animation and using the sprite 'Knob' that already ships with Unity.

Hope it helps

I've been "playing" with it a little bit and I managed to make something that could interest you. There's a slider for radius and a slider for the number of verts. $$anonymous$$ore verts -> more quality. I leave you the scene here. If you need further clarification please ask.
