Spinner, Line & Shapes

spinner

Rotating arc loading indicator.

ui:element({
    id = "loading", type = "spinner",
    rect = { unit = "px", x = 10, y = 10, w = 40, h = 40 },
    style = { color = "#38BDF8", thickness = 4 },
})

Style	Description
color	Arc color (default accent blue)
track_color	Background track color
thickness	Arc thickness in pixels (default 4)
arc_length	Fraction of full circle (default 0.3)
speed	Rotations per second (default 2)

line

A line between two points. Element rect is ignored — positioning via props.

ui:element({
    id = "sep", type = "line",
    rect = { unit = "px", x = 0, y = 0, w = 0, h = 0 },
    props = { x1 = "10", y1 = "50", x2 = "200", y2 = "50" },
    style = { color = "#334155", thickness = "2" },
})

Prop	Description
x1, y1	Start point
x2, y2	End point

Style	Description
color	Line color (default white)
thickness	Thickness in pixels (default 2)

rect_outline / border

Outline-only rectangle (no fill).

Style	Description
color	Outline color
thickness	Border thickness in pixels (default 2, same as Unity Outline distance)

circle

Filled ellipse (inscribed in rect) or elliptical outline ring. The renderer uses a mesh Graphic, not a square Image, so equal w/h gives a true circle. Fill vs stroke is controlled by props.filled, not by thickness.

-- Filled (default): use style.bg for the fill color (style.color is ignored)
ui:element({
    id = "led",
    type = "circle",
    rect = { unit = "px", x = 100, y = 100, w = 50, h = 50 },
    style = { bg = "#B36200" },
})

-- Outline only: set filled to false; use style.color and style.thickness
ui:element({
    id = "ring",
    type = "circle",
    rect = { unit = "px", x = 160, y = 100, w = 50, h = 50 },
    props = { filled = false },
    style = { color = "#B36200", thickness = 3 },
})

Prop	Description
filled	Omit, empty, true, or 1 for filled disk (default). false or 0 for outline only.

Style	Mode	Description
bg	Filled	Fill tint (default white).
color	Outline	Stroke color when filled is false (default white).
thickness	Outline	Unity Outline distance in pixels (default 2).
