Function: list ListXandY(list lx, list ly);
This function examines two lists, and returns a new list composed of the elements that both lists have in common.
<lsl> list ListXandY(list lx, list ly) {// return a list of elements common to both lists
list lz = []; integer x;
for (x = 0; x < llGetListLength(ly); x++) {
if (~llListFindList(lx,llList2List(ly,x,x))) {
lz = lz + llList2List(ly,x,x);
}
else {
;
}
}
return lz;
} </lsl>
Example:
<lsl> list l1 = ["a","b","c","d"]; list l2 = ["a","1","b","2","c","3"];
default{
state_entry() {
llSay(0, "The new combined list is: " + llList2CSV(ListXandY(l1,l2)) );
//will say: a, b, c
}
} </lsl>
