drawRectFilled

Draws a solid, filled rectangle between two defined points on the screen or canvas.

Signature

ui.drawRectFilled(p1, p2, color, rounding, roundingFlags)

Description

This function renders a filled rectangle. The shape is defined by an axis-aligned bounding box calculated from points p1 (usually top-left) and p2 (usually bottom-right).

Outlines

If you require a hollow rectangle (borders only), use ui.drawRect instead.

Parameters

Parameter	Type	Required	Default	Description
p1	vec2	Yes	-	Screen coordinates for the first corner.

Examples

Transparent Background

Draw a semi-transparent black background box.

local p1 = vec2(0, 0)
local p2 = vec2(200, 100)
local black = rgbm(0, 0, 0, 0.5)

-- black with 50% opacity
ui.drawRectFilled(p1, p2, black)

Rounded Button

Draw a filled green shape with fully rounded corners (pill shape).

local p1 = vec2(50, 50)
local p2 = vec2(150, 90)
local green = rgbm(0, 1, 0, 1)
local radius = 20

-- radius of 20px for smooth corners
ui.drawRectFilled(p1, p2, green, radius)
