I made a racetrack game. I am trying to make it scalable on mobile devices.
I achieved to make it look ok when device orientation is normal (vertical) :
But when I rotate the device to a horizontal view this happens : (how to zoom it out a bit )?
What would you recommend doing? I used display: none to hide the images. I would really appreciate any help.
Edit: I've managed to do this but the view is still too much zoomed, any ideas?
const width = 800;
const height = 600;
const pixelRatio = window.devicePixelRatio || 1;
canvas.width = width * pixelRatio;
canvas.height = height * pixelRatio;
canvas.style.width = `${width}px`;
canvas.style.height = `${height}px`;
// for sprites scaled up to retina resolution
canvas.mozImageSmoothingEnabled = false;
canvas.imageSmoothingEnabled = false;
c.scale(pixelRatio, pixelRatio);
