drawCircle

Draws an unfilled circle outline around a specific center point.

Signature

ui.drawCircle(center, radius, color, segments, thickness)

Description

This function renders the outline of a circle. The smoothness of the circle depends on the number of segments used to draw it.

Filled Circles

This function only draws the outline (stroke). If you require a solid shape, use ui.drawCircleFilled instead.

Parameters

Parameter	Type	Required	Default	Description
center	vec2	Yes	-	Screen coordinates for the center of the circle.
radius	number	Yes	-	The radius of the circle in pixels.
color	rgbm	Yes	-	The color and opacity of the outline.
segments	integer	No	0 (Auto)	The number of vertices used to draw the circle. Higher values result in smoother curves.
thickness	number	No	1.0	The width of the outline stroke in pixels.

Return Values

• None

Examples

Basic Usage

Draw a standard white circle.

local center = vec2(100, 100)
local radius = 50

-- draw a white circle with default smoothness
ui.drawCircle(center, radius, rgbm.colors.white)

Regular Polygon

By lowering the segment count, you can create regular polygons.

local center = vec2(200, 100)
local radius = 50

-- 6 segments creates a hexagon
ui.drawCircle(center, radius, rgbm.colors.red, 6, 3.0)
