Scott Murray Full Member Offline Posts: 117 San Francisco	Dead simple question Feb 26th, 2009, 10:56pm   This is driving me nuts.  I'm trying to get a value from 0.0 to 1.0, based on how far the mouse is from the left of the screen. Code: void setup() { size(300, 300); } void draw() { float relativeMouseX = mouseX / width; println(relativeMouseX + " " + mouseX + " " + width); } Why does mouseX divided by width always give me 0.0?
