How keep codea happy?

Questions
1

Hi, guys. Sorry for noob questions from me, but whats wrong in this piece of code?

Fishes = class()

function Fishes:init()
    -- you can accept and set parameters here
    self.fish = physics.body(CIRCLE,20)
    self.fish.x = 100
    self.fish.y = 0
end

function Fishes:draw()
   ellipse(self.fish.x,self.fish.y,40) -- this string makes codea unhappy
end

function Fishes:touched(touch)
    -- Codea does not automatically call this method
end

I expect codea dont like this values : “self.fish.x and self.fish.x”

works fine for me
i assume you wrote

    f.draw()

instead of

    f:draw()

@Jvm38 Im foregin and sometimes i understand your advices like slowpoke,but what you mean?

4 
do you see the '.' instead of ':'

i suppose you made a typo mistake when calling the draw().
This is very common when you begin with lua…

@Jvm38 no. I understand this. But problem in something else

6

then post the whole code, what you have posted works fine.

7

btw, what do you mean ‘makes codea unhappy’? can you post the error text?

PS: sorry for my short answers, i hope you dont feel this as rudeness. I just try to be quick and concise.

this makes no sense:

draw()
    Fishes:draw()
end

Fishes is a class, not an instance of the class, you must create and draw one sample fish1 or more:


--# Main
-- Kraken
-- Use this function to perform your initial setup
displayMode(FULLSCREEN)
function setup()

    w = WIDTH/2
    h = HEIGHT/2
    xb = w
    xs = h
    xch = 270
    xch = xch + 1
    count = 1

    floor = physics.body(EDGE,vec2(-WIDTH,0),vec2(WIDTH,0))
    physics.pause()

    grav = physics.gravity(Gravity)
    ship = physics.body(CIRCLE,89)
    ship.y = h+199
    ship.restitution = 1

    fish1 = Fishes()

end
function touched(touch)
    if touch.state == ENDED then
        physics.resume()
    end

end

function outofscreen()

        if xb > w then
        xb = 0
        count = count + 1
        elseif xb < w then
        xb = 0
        end
       if xs > w then
        xs = -20
       end

end


function draw()  
    xch = xch + 1
 --   if touch.state == ENDED then
--    ship.y = grav.y


 --   end
    pushStyle()
    sprite("Documents:backgroundblur",w,h)
    sprite("Documents:waveback",w-200,h+300)
    sprite("Documents:waveback",w+250,h+300)
    sprite("Documents:ship(vlad dont like this)",xch,ship.y,270,178)
    sprite("Documents:wavefrontbig",w,h+280)
   -- sprite("Documents:wavefront",w+440,h+290)
    popStyle()
    fish1:draw()

end


--# Fishes
Fishes = class()

function Fishes:init()
    -- you can accept and set parameters here
    self.fish = physics.body(CIRCLE,20)
    self.fish.x = 100
    self.fish.y = 0
end

function Fishes:draw()
   ellipse(self.fish.x,self.fish.y,40)
end

function Fishes:touched(touch)
    -- Codea does not automatically call this method

@Jvm38 thank you very much
