i need help with creating a function. how can i create a function that decides true or false on an object i click on.

i have everything else set up, have my "when mouse is clicked on 'anything' do 'method' - 'what was picked'" event.

but i just cant figure out how to relate the click event to my function, and how to get my function to include/exclude certain objects from true/false.

i hope this makes sense to everyone :/.
