Add filled and width parameters to draw_circle

Describe the project you are working on

Describe the problem or limitation you are having in your project

• draw_rect has a filled parameter and a width parameter for the cases where you want to draw a non-filled rect.
• draw_circle doesn't have that, forcing you to use draw_arc with a big angle whenever you want an unfilled circle (and forcing you to discover it in the first place).

btw, a filled circle is a disk, so draw_circle doesn't technically draw circles.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Add the fitting parameters and functionality to draw_circle. It would feel natural to me. Having this as a parameter allows to quickly switch between the filled and unfilled versions when needed, without the need to rewrite the line.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

draw_circle(position: Vector2, radius: float, color: Color, filled := true, width := -1.0)
The parameter order would be the same as draw_rect for consistency.
Behavior should be the same too:

• if filled == true, the current behavior remains
• if filled == false, then a circle of with width is drawn. I think width == -1.0 means 1 screen pixel.

I guess internally it could simply branch to draw_arc with an automatic point count, but that's the naive way. I don't know if it's easy to make it draw an actual circle, and what performance difference there is with a filled one.

If this enhancement will not be used often, can it be worked around with a few lines of script?

it can be worked around with draw_arc, but it's more verbose and harder to find. It also has a point_count, so no true circles.

Is there a reason why this should be core and not an add-on in the asset library?

it's about improving core

Note that draw_arc and draw_circle work very differently internally

If a width parameter is implemented, then antialiased should also be added to match draw_line().
