Hi there,


Started with Processing not a long time ago, and creating a real time illustration application I have found a problem. Basically I am drawing ellipses en each mouseX and mouseY position under MousePressed and running at about 900 fps.

I have found that the mouseX and mouseY values are not updated fast enough when moving the mouse fast in the screen, which results in the ellipses being drawn separated from one another if the mouse moves too fast.

Is there a way to update the values of the mouse coordinates in a faster way like accessing the Java code directly, or should I use another way like drawing curves and interpolating the points, for example?


Thanks so much for your help!

use the mouseMoved() event to get every mouse move event that's passed in from the system:
http://processing.org/reference/mouseMoved_.html
when used inside draw(), mouseX/Y are only updated once per trip through draw().

but like johng says, you're not gonna get "exact" mouse movement with no gaps, no operating system does that.
