Question about Parameter().

Can I position the slidebar elsewhere?
What about Vertical ?
Is their special “view” I can use?

I am trying to get two VERTICLE slider bars on left and right side of a landscape screen.
Basically I want the user’s thumbs to move a slider bar up and down.

I’m new to Codea so be gentle.

Thanks,
Troy

You can use displayMode(FULLSCREEN) or alternatively press the FullScreen button when running your script. Then you can create the slider bars yourself or use a pre-existing class such as npryces controller class which is my favourite, and its very easy to implement for beginners.

Where is the controller at ?
Examples on how to implement it ?
I searched for npryces controller class & npryces controller and
could not find it.

Is it as simple as creating a NEW TAB and adding the Code in question ?

Thanks for the response,
Troy

Here’s a simple example. Slide you thumbs up or down the right or left side of the screen. The counters increase each time you slide up and decrement each time you slide down. I put in simple sliders because I don’t know what you want exactly.


supportedOrientations(LANDSCAPE_ANY)
displayMode(FULLSCREEN)

function setup()
    x1=0
    x2=0
end

function draw()
    background(40, 40, 50)
    fill(255)
    text(x1,100,HEIGHT/2)  -- show values
    text(x2,WIDTH-100,HEIGHT/2)
    drawSliders()
end

function touched(t)
    if t.x<WIDTH/2 then
        x1=x1+t.deltaY  -- left value
    else
        x2=x2+t.deltaY  -- right value
    end
end

function drawSliders()
    rect(10,HEIGHT/2+x1,50,10)  -- show sliders
    rect(WIDTH-60,HEIGHT/2+x2,50,10)
end
