So I thought I was getting the hang and understanding a little now I can’t do crap from new project I’m getting really frustrated I can’t get anything to show up on screen when I run. I’m trying to simply creat two circles and have them rotate around each other.

Circle one rotate around circle two when you tap the screen they switch cir 2 rotates around cir 1. Here is my code so far

Main class:

function setup()
function createCircle(x,y,r)
local circle = physics.body(CIRCLE, r)
-- enable smooth motion
circle.interpolate = true
circle.x = x
circle.y = y
circle.restitution = 25
circle.sleepingAllowed = false
return circle
end
end
```
Then circle class:

Circle = class()
function Circle:init(x, y, size)
-- you can accept and set parameters here
self.x = WIDTH/2
self.y = HEIGHT/2
self.size = 25
end
function Circle:draw()
pushStyle()
fill(180,10,30)
ellipse(self.x, self.y, self.size)
popStyle()
end
-- Codea does not automatically call this method
function Circle:touched(touch)
-- Codea does not automatically call this method
end
```
Please help what am I doing wrong lol

.@DeanC1985 your circle class is good but you need to call it from your main program to initialise and draw it. Getting the circles to rotate round each other was a bit tricky but the following should work. I included a basic tap control and the option for you to modify to anticlockwise rotation if you wish

--# Circle
Circle = class()
function Circle:init(x,y,r,state)
-- you can accept and set parameters here
self.x = x
self.y=y
self.size=r
self.state=state
self.rotspeed=0.02
end
function Circle:draw(p)
self.p=p
ellipse(self.x,self.y,self.size)
local dist=math.sqrt(((self.x-self.p.x)^2)+((self.y-self.p.y)^2))
local angle=math.atan2((self.x-self.p.x),(self.y-self.p.y))
if self.state==CLOCKWISE then
self.x = self.p.x + dist*math.sin(angle+self.rotspeed)
self.y = self.p.y + dist*math.cos(angle+self.rotspeed)
end
end
function Circle:touched(touch)
-- Codea does not automatically call this method
end

And

--# Main
-- circle demo
-- Use this function to perform your initial setup
function setup()
STATIONARY=0
CLOCKWISE=1
ANTICLOCKWISE=2
c1=Circle(WIDTH/2,HEIGHT/2,50,STATIONARY)
c2=Circle(WIDTH/4,HEIGHT/2,50,CLOCKWISE)
timer=0
touches={}
end
-- This function gets called once every frame
function draw()
-- This sets a dark background color
background(40, 40, 50)
c1:draw(c2)
c2:draw(c1)
for k,touch in pairs(touches) do
-- Use the touch id as the random seed
if (math.abs(touch.x-c1.x)<20 and math.abs(touch.y-c1.y)) or (math.abs(touch.x-c2.x)<20 and math.abs(touch.y-c2.y)) then
if c2.state==STATIONARY then
c2.state=CLOCKWISE
c1.state=STATIONARY
else
c1.state=CLOCKWISE
c2.state=STATIONARY
end
touches[k] = nil
end
end
end
function touched(touch)
if touch.state == ENDED then
touches[touch.id] = nil
else
touches[touch.id] = touch
end
end
