very simple question about line()
May 27th, 2009, 2:03pm  
hi,

I was trying to make a little crosshair in an app that would show up rather than the cursor, so I wrote this:

 noCursor();
 line(mouseX-2, mouseX+2);
 line(mouseY-2, mouseY+2);

then I got the following error:

"The method line(float, float, float, float) in the type PApplet is not applicable for the arguments (int, int)."

This confused me because I thought that the mouseX and mouseY variables were ints, not floats.

Is there something else that I'm doing wrong here?

Thanks! Smiley

I think the trouble is that you only have two arguments, line() expects a start x/y and an end x/y.

Also, don't forget you can just call Code:
cursor(CROSS);
to switch to a crosshair pointer automatically.  Wink
