I'm making a game like Doodlejump but don't know how to make the physics scale on multiple resolutions. I also can't find anything related to this on Google. Right now I'm scaling the game using letterboxing and tested scaling the jump height with this code:
gravity = graphics.getHeight() * 0.001f;
jumpVel = graphics.getHeight() * -0.04f;
velY += gravity;
y += velY;
But if I test this on my smartphone or emulator with different resolutions, I always get a slightly different jump height. I know that Farseer is resolution independent. How can I replicate this in my game?
Thanks in advance.
