Function: list ListXorY(list lx, list ly);
Join two lists to make one new combined list, while also eliminating any resulting duplicates in the new list.
<lsl> list ListXorY(list lx, list ly){ // add the lists eliminating duplicates
list lz = []; integer x;
for (x = 0; x < llGetListLength(ly); ++x){
if ((integer)~llListFindList(lx,llList2List(ly,x,x))){
;
}
else {
lz = lz + llList2List(ly,x,x);
}
}
return lx + 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(ListXorY(l1,l2)) );
//will say: a, b, c, d, 1, 2, 3
}
} </lsl>
