I need help with setContext() and Codea Crashes.

Anatoly

This code:

function CreateGraphic:formula()
    --[[
    Function is called like this in 'draw':

    local img = self:formula()
    sprite(img, (WIDTH+225)/2, HEIGHT/2+50, 700, 450)
    ]]

    img = image(450, 300)
    setContext(img)
    fill(127, 127, 127, 255)
    rect(0, 0, 450, 300)
    setContext()
    return img
end

It's definitely this function, because when commenting it, it won't crash Codea.

The function looks like it calls itself, so it goes round and round until it crashes

Anatoly

What do you mean by "calls itself"?
I am not calling the function anywhere else...

Anatoly

Instead of making another function, I have put the code part in 'draw', and it was still crashing:

    -- Show Diagramm
    img = image(450, 300)
    setContext(img)
    fill(127, 127, 127, 255)
    rect(0, 0, 450, 300)
    setContext()
    sprite(img, (WIDTH+225)/2, HEIGHT/2+50, 700, 450)

Still crashes

Ignatz

Why are you using setContext every time you draw?

Anatoly

Okey, Fixed, creating new images 60 times a miliseconds is crashing Codea.

Just made it being elements...

Hi,

Try putting your image generation in setup then just sprite the image in draw:

displayMode(OVERLAY)
function setup()

    img = image(450, 300)
    setContext(img)
    fill(127, 127, 127, 255)
    rect(0, 0, 449, 299)
    setContext()

end

function draw()

    background(50,50,50,255)

    sprite(img, WIDTH/2, HEIGHT/2)

end

Make sure the size of your img is the same size as the rectangle.

But it should be updated automatically...
