Draw circle?

Ninjadoodle · August 2017

Hi guys,

I'm just searching through the forums, trying to figure out a simple way to draw a circle.

If anyone could point me in the right direction, that would be awesome

Thanks heaps!

this should give you some ideas, after all a moon is similar to a circle...

i've found this by googling:
"M 50 10 A 40 40 0 1 0 50 90 A 40 40 0 1 0 50 10 Z M 50 30 A 20 20 0 1 1 50 70 A 20 20 0 1 1 50 30 Z"

Hi @keszegh

Thank you heaps for the link! I've had a play around with the code ... and I think I will just use a png lol.

I'll come back to it later and try and understand it a bit better

Thanks again!

png's are indeed simpler to handle, although these svg codes are not impossible to understand neither (not that i do understand them).

A quick and nasty filled circle..

 
local function newCircle(x, y, r, steps, color)
  local sin, cos, d2r = math.sin, math.cos, math.pi / 180
  color = color or 0x4488cc
  local c = Shape.new()
  c:setFillStyle(Shape.SOLID, color)
  c:setLineStyle(0)
  c:beginPath()
  c:moveTo(r * sin(0 * d2r), r * cos(0 * d2r))
  for i = 0, 360, 360 / steps  do
	  c:lineTo(r * sin(i * d2r), r * cos(i * d2r))
  end    
  c:endPath()
  c:setPosition(x, y)
  return c
end
 
local c = newCircle(200, 100, 100, 70)
stage:addChild(c)
