We are about to switch to a new forum software. Until then we have removed the registration on this forum.
First thing's first: I just started with Processing about 2 weeks ago, and Android mode a couple days ago, so anything you say should assume very little knowledge but the basics of Java mode. Okay, now. If I have a basic ball bouncing game ported from Java mode, different pixel densities cause the ball the be all different sizes from device to device, so how can I make the ball be a fixed size across multiple platforms?
