Waterlurker (Kaernk) pathnode

[FlawlessHappiness]

Yea so i know there have been more threads with these question, but i never really got an answer...

I know how to give a monster pathnodes and so on. I know they can't cut corners so i will have to give the waterlurker a pathnode, so it doesnt just get stuck between boxes... But i guess when it finishes its pathnodes it will disappear.

Read about the looping of pathnodes, but all i got was:

SetEntityActive("servant_grunt_1",true);
for (int i = 1; i <11; i++)
{
int x = i;
if (i == 1)
{
x = 2;
}
if (i == 10)
{
x = 4;
}
if (i != 1 || i != 10)
{
x = 0;
}

This makes no sence to me. Could somebody please explain to me what the values means? So i can put my own informations in the script?
