circle.intersects( rect )

[sandyd]

Ive used the circle.intersects function to see how many times the circle (thats drawn at the place where i click the mouse) intersects a floating rectangle each time i click. is there a function to see how many times it DOESN'T intersect?

P.S. i can't just subtract the total clicks because on some occasions, the circle will intersect multiple objects and i want to know how many shots were fired that actually hit something and how many shots that didn't hit anything at all, not how many objects were destroyed

Umm.. I do not understand the context of the question, but... uh... a circle and rectancle intersect a maximum of 8 times, so perhaps the amount of times they don't intersect is 8 - intersections? :confused:

As CptPicard wrote, it is hard to guess what you are actually meaning. Nevertheless, it look like that you are actually referring to something simple. So you have some code like:



for r in rectangles:
for c in circles:
if c.intersects(r) then:
do some stuff

You can use a boolean variable to track if you had some hit.



for r in rectangles:
hit = false
for c in circles:
if c.intersects(r) then:
hit = true
do some stuff
if not hit:
do whatever you want if there's no hit

Note that this is just the general idea, no ready-to-use code!
