Name
mouseX
Description
The system variable mouseX always contains the current horizontal
coordinate of the mouse.
Note that Processing can only track the mouse position when the pointer
is over the current window. The default value of mouseX is 0,
so 0 will be returned until the mouse moves in front of the sketch
window. (This typically happens when a sketch is first run.) Once the
mouse moves away from the window, mouseX will continue to report
its most recent?position.
Examples
void draw() { background(204); line(mouseX, 20, mouseX, 80); }
