why is this simple app freezing processing?

hello p5 companions! I'm testing the get pixels function, but I don't know why something really simple freezes processing everytime (v68 - mac os X)... any ideas? void scheck(int cx, int cy, int cw, int ch) { for(int i=cx;i<=(cx+cw);i++) { for(int j=cy;i<=(cy+ch);j++) { color actual = get(i,j); println(i+" "+j+" "+actual); } } } void setup() { size(200,200); } void draw() { scheck(1,2,3,4); } it's just an application to get the colors from a certain area... what's wrong? Thanks! from "the guy with a grand canyon between real world problems and algorithms"

There's an i/j mix-up in your second for loop. Since i doesn't change once you enter the second loop, you never meet the stop condition.

DOH! Sorry guys, I've been not sleeping for a few days... dumbest-problem-post-ever award goes to me. By the way, is there any keyboard shortcut to break the application and stop the infinite loop? I was force-quitting processing all the times.

| nah, everyone makes this error, especially after working too long and/or sleeping too little. well, at least i know i've done it. though usually in c++ where it horks my whole machine.
