Can't find API for drawing a circle on screen that's not on minimap or in 3D plane.

(external if it matters)

Surely it exists right?

if it doesn't might be able to make my own function with the source of Draw.CircleMinimap(...) if that's even public?

Are you talking about this ?

But thats only for minimap . Why u need 2D draw tho ?

[spade]

I wanted a 2D circle for cursorPos, 3D looks off

[Zypppy]

well the circle draw around mouse in  Gamsteron AIO works pretty smooth 

[spade]

it uses the same 3D method though ..

there's no way to draw circle in 2D plane then I assume?

[Zypppy]

Not that I know of

Yes, you can code your own function for it:

local pi, cos, sin = math.pi, math.cos, math.sin
local assert = assert
local Vector = Vector

function DrawCircle2D(obj, r, q) --gameObject, range, quality => 1-100
   assert(obj.pos2D, "Could not find 2D-coordinates for this object")
   local r, q = r or 50, q and 2 * pi / q or 2 * pi / 20
   local x, y = obj.pos2D.x, obj.pos2D.y
   local pts = {}

   for th=0, 2 * pi + q, q do
     local pt_x, pt_y = x + r * cos(th), y - r * sin(th)
     pts[#pts+1] = Vector({x = pt_x, y = pt_y})
   end
  
   for i=1, #pts do
     local pt1, pt2 = pts[i], pts[i+1] or pts[1]
     Draw.Line(pt1, pt2)
   end
end

function OnDraw()
   DrawCircle2D(myHero, 500, 100)
end

Thank you for your help, it looks great;
