Problem with Mouse or Key Pressed

Hey!

It seems like Processing doesnt realize when i make a mouseclick or press a key.

So I want to ask if someone out there had this problem too and knows how to solve it

Thanking you in anticipation!

Can you post your code?

void mouseClicked(){

newNumb();

print("hello");

}

void newNumb(){

if(mouseX > 50 && mouseX < 500 && mouseY > 50 && mouseY < 500)

{

int a = ((mouseX - 50) - (mouseX%50))/50;

int b = ((mouseY - 50) - (mouseY%50))/50;

values[a][b]=0;

print(a + "," + b + " ");

}

It doesnt even print "hello".

I also tried a simple code in a new file to test mouseClicked() generally!

Looks fine (apart from ref to undeclared 'values' array) and works for me. What OS and version of Processing are you using?

You have placed setup() and draw() loops in the sketch, of course?

No probs.

If you don't include setup()/ draw(), the mouse and key listeners will not be called.

setup() isn't necessary for it. Only draw().
