Overview

  Creates a circle shape.

  Circle class inherits Display class, therefore all the methods defined in Display class can also be used in the Circle object.

Syntax

Circle(radius  [,option] )

    • radius - (required) the radius of the circle

    • option - (optional) table containing parameters

        option = {

                strokeWidth = n, -- (default = 0) width of stroke

                strokeColor = color, -- (default = Color.WHITE) stroke color

                fill = color, -- (default = Color(Color.WHITE,1)) color and alpha for fill

        }

  Note that the initial anchor point is the center of the circle.

Methods

method	description
obj:setStrokeWidth(n)	set width of outline
obj:setStrokeColor(color)	set color of outline with Color object
obj:fill(color)	set color of inner area with Color object
obj:empty()	display stroke only
obj:setRadius(num)	change radius as num

Note that all the methods in Display class are callable.

Examples

Circle(100)

local c = Circle(100,{fill=Color.RED})

local c= Circle( 100, {strokeWidth=10,strokeColor=Color.BLUE} ) Timer(5000, function() c:setStrokeColor(Color.RED) end) -- change stroke color after 5 seconds

local c = Circle(100, {     fill=Color.RED,     strokeColor=Color.YELLOW,     strokeWidth=10, } )
