Hello guys, i need some help with layers in codea. Its not a secret, what codea do draws anything on “layers”, like in photoshop. And i dived my project on classes. So i have background class, interface and so on. I need to draw something, what is moving on one layer, then it reaches border draw on another layer under this one and continue this moving. There is picture what i need

draw your balls first, and your yellow layer last, it will do what you want.

@lupino8211 If you need an example.

displayMode(FULLSCREEN)

function setup()
    x,y=0,WIDTH/2
end

function draw()
    background(31, 93, 110, 255) -- draw blue background first
    fill(255,0,0)
    ellipse(x,y,100)    -- draw red circle second
    fill(255, 222, 0, 255)
    rect(WIDTH/3,0,WIDTH/3,HEIGHT)  -- draw yellow rectangle last
    x=x+1
end

@dave1707 i know it, i wonder: can i jump from layer to layer by one circle. In case i need make only second way from picture, then one side of picture is still visible and second one is not

@lupino8211 Sorry, I’m not sure what you’re trying to do with you’re next question.

@lupino8211 - try this. use translate to separate your layers

function setup()
   pos=vec2(0,HEIGHT/2) 
    speed=1
end

function draw()
    background(0)
    pushMatrix()
    translate(0,0,1)
    fill(0, 152, 255, 255)
    rect(200,200,600,600)
    translate(0,0,2)
    fill(101, 255, 0, 255)
    rect(400,400,200,200)
    popMatrix()
    translate(0,0,1)
    fill(255,255,0)
    ellipse(pos.x,pos.y,100)
    pos.x=pos.x+speed
end
