How do I create circle sprite

I want to create a circle but it still has a square shape,i mean even if you made a circle sprite its borders will be square.you cant make a circle so is there any other way?

Use the brush icon and change the radius.

use paint ? or photoshop?

No I don't mean this,I can make a circle I just don't know how to change the borders of the editor itself not the sprite.Anyway I don't have construct 2 opened infront of me right know,but when I open it I will try spongehammer's idea

The sprite will always be a square since its an image at say 64x64 pixels. If the problem is the collisions you can set the colission polygon in the image editor. I dont think that what you are asking for is possible.

Do you want to change the collisions of the sprite?

If you have a sprite and open it in construct and click the icon at the bottom "set collision polygon" there you can edit the shape or you can just right click on the sprite and click "guess polygon shape" and then move the points so it fits exactly how you want. You can then right click on a point to add another. Super easy

Thx you two guys!you helped me a lot!i will try what you said

u talking about the collision? when u open animation, u have a set of tools in editor, if u go to collision by default is a square , if u right click and select autodetect shape will automatically detect ur shape )

Well,I think I asked the question wrong,but yes I meant the collisions and thanks for answering!
